Secular Science Education: An Integrated Science Essay

Physics, Chemistry, Biology, Earth Science, and Astronomy

Supervolcanoes are a captivating topic that bridges multiple scientific disciplines, making them a perfect subject for secular science education. From the dramatic eruptions that shaped Earth’s landscapes to the intricate chemical processes hidden within volcanic ash, studying these natural phenomena offers valuable insights into physics, chemistry, biology, earth science, and astronomy. This essay delves into the fascinating world of supervolcanoes, showcasing how interdisciplinary science helps us understand and prepare for the dynamic forces shaping our planet and beyond.

Ashfall Fossil Beds Discovery

In 1971, the young geologist Mike Voorhies and his wife, Jane, were strolling along a gully on the edge of a farm in northeast Nebraska not far from where they lived. Since he was a little kid, Mike had been fascinated by fossils, having found his first ancient camel tooth at the age of 8.  On that day by the gully he happened to notice what looked like an animal skull protruding from the eroding edges. Within minutes, he and Jane unearthed not just the skull but the entire skeletal remains of a 12 million year old rhinoceros. They had discovered what has since become known as the Ashfall Fossil Beds of Nebraska.

Further explorations revealed the remains of hundreds of large vertebrate animals who, around a water hole, had died together upon being buried by a meters thick layer of ash. The source of this ash? A supervolcano 1000 miles to the west—an earlier version of the very same supervolcano that now resides beneath Yellowstone National Park in northwest Wyoming.

Secular Science Education: What Makes a SuperVolcano

As one learns from the study of Earth Science, the outer layers of Earth are broken into tectonic plates, looking much like the cracked shell of a hard boiled egg. About 95% of Earth’s volcanoes arise along these cracks. These volcanoes are certainly destructive, but they pale in comparison to the fewer “supervolcanoes”. These supervolcanoes tend to form not on the edge, but in the middle of a plate over what we call a “hot spot”, which is where there is a direct line between Earth’s molten core and the surface. Yellowstone resides over just such a hot spot, which explains its many natural hot springs along with frequent earthquake activity.

The Yellowstone Supervolcano

The Yellowstone super volcano has a history of blowing up around every 600,000 years. Notably, the last mega-explosion occurred about 630,000 years ago, which means that we are due for another mega-explosion at any time. Yellowstone, however, is one of the most closely studied and monitored volcanoes around the planet. Over the next 100,000 years, the chances of another explosion are quite good.  The chances for this happening over the next century, however, are exceedingly small. As of this writing, the Yellowstone super volcano is showing no unusual signs of impending doom.

But that doesn’t stop scientists from wanting to learn as much as we can about this volcanic system. In 2017, for example, geology graduate student Hannah Shamloo, and her advisor, Christy Till, from Arizona State University, published research showing that the build up to the last major eruption of Yellowstone may have occurred over a matter of only years or decades, as opposed to thousands of years. But how exactly did they come to this conclusion? After all, we’re talking about a supervolcano that erupted some 630,000 years ago.

We all have observational skills.  Part of what secular science education or becoming a scientist means is training those observational skills to a deeper level. Mike Voorhies was trained in what to look for with fossils. Similarly, as a graduate student, Hannah Shamloo, was being trained in what to look for within the micro-crystals found within volcanic ash.

Decoding Volcanic Clues: Phenocrysts and Magma Dynamics

Hannah and her team first traveled to Yellowstone to collect samples of ash from the layer corresponding to the last mega-explosion. Back in the laboratory she used instruments to measure the chemical composition of micro-crystals known as phenocrysts—tiny crystals that form as magma cools slowly beneath the volcano prior to eruption. She had learned that as these crystal grows, trace elements, such as barium, Ba, get embedded within the crystal. The gradient from the center of the crystal to the outer edges, thus provides a storyline of the changing conditions beneath the volcano prior to eruption. 

If there were no changes in the conditions of the magma over time, then the chemical composition would be the same throughout the crystal. What she found instead were chemical changes that showed two things: a rapid increase in the temperature of the surrounding magma and an increasing amount of a crystallized barium.

The problem with this is that with increasing temperatures, barium tends to stay out of the crystal and within the molten magma—yet with higher temperatures, they found the barium content of the crystals actually increasing! Further analysis also showed a relatively low content of water within the crystals. This was telling because a major mechanism for volcanic explosions is the presence of large amounts of water, which helps in the building of pressure.

Secular Science Education: SuperVolcanoes - Phenocryst Crystal Diagram

Here was important evidence within these tiny phenocryst crystals. And like a thoughtful Sherlock Holmes, they realized this pointed to a likely alternate mechanism of the last mega-explosion.  Their observations within those phenocrysts could be explained by the rapid influx of a large quantity of magma from deep below over not thousands of years, by potentially only decades. If true, it means that present-day Yellowstone could go from its current conditions to a major explosion within this century.

As Hannah and her advisor are quick to point out, much more research is required to support or refute these conclusions. Further, the subterranean magma chambers, as far as we can track, are currently not undergoing major movements. Thus, geologists estimate chances of a mega-explosion occurring within a year to be about 1 in 760,000. The slow release of lava, which would devastate only the area around the national park, has a greater chance of occurring at about 1:10,000.

Living on a Dynamic Planet: The Value of Integrated Science

The main point to all of this is that we live on a planet that is very much alive. When it comes to volcanoes, earthquakes, tsunamis, wild fires, tornados, hurricanes, and other destructive forces, the more we can learn about these systems, the better we are able to prepare ourselves.

Secular Science: SuperVolcanoes - Photo of the 1991 Mount Pinatubo Erruption

But beyond the benefit of preparing for potential disaster, there are many other benefits to learning about how nature works. Perhaps foremost are the perspectives we gain. There are the why questions: Why is the sky blue? Why is the Sun hot? Why does water take so long to boil? There are also the “how” questions: How do we know dinosaurs lived over 65 million years ago? How do we know an antibiotic won’t cure a viral infection? How do we know increasing atmospheric carbon dioxide levels are affecting global climate? 

Science is a powerful tool for answering these sorts questions. As exemplified by the research into supervolcanoes, science is becoming increasingly interdisciplinary, or in other words “integrated”. To study her field of earth science, Hannah Shamloo needed to know how it is that magma is hot and generally rises upward (Physics). She needed to know how crystals precipitate from magma and how chemical composition can serve as a fingerprint in her detective work (Chemistry). And much of her inspiration arises from wanting to help protect ecosystems (Biology).  And by no coincidence, her research will help in the study of extraterrestrial worlds, such as Io, a highly active volcanic moon of Jupiter (Astronomy). Integrated science is good science. It’s also enjoyable science and very much related to our everyday lives.

Homeschool Tips: How to Talk to Kids About Scary Science

Blair Lee, M.S.

Homeschool Tips for Tackling Scary Science Topics

From the climate crisis and anti-vaccine misinformation to the coronavirus, it seems that every time you turn on the news, science is presented as something frightening. These topics can leave you and your children feeling worried and powerless to make a difference. It is a common occurrence in the SEA Homeschoolers Facebook group to have parents ask for homeschool tips to help with talking to their kids about these scary science topics. Parents are often worried that talking about them will make their child even more afraid. 

So how do you discuss them? How do you address science topics in a way that does not alarm your children even more? Perhaps it would be better to just say nothing? As parents we want to allay our children’s concerns and let them know everything is going to be okay. But what do you say if you are not sure that’s true? 

Talking about scary science is something I do often. Here are my tips for how I deal with it with my grandkids and in the classes that I teach.

My Go-To Tips for Navigating Tough Science Conversations

1. Talk About Scary Science

If you and your child are worried about scary science, address it. Be willing to have big, meaningful, meaty conversations about scary science topics. Do this in an age and stage appropriate way. The older your child is, the bigger the conversations can and should be. 

When these issues aren’t discussed, I think of it as “pretending they don’t exist and hoping they’ll just go away.” All this does is create “elephants in the room”—issues your child needs help addressing so they feel less scary. You can help dispel the “elephants” by having honest conversations about the science.

2. Teach the Science

Education is an essential early step for dealing with scary science. Science literacy is an important part of allaying fears. For example, coronavirus is scary. If you and your child understand the science of germ theory and how vaccines work, you can minimize the risks of getting coronavirus and reduce fears about it. The science explaining global warming and climate change is not complicated. Understanding the science is the best way for your children and you to feel empowered instead of powerless.

3. Use Adequate, Credible Sources

We live in the age of social media. Unless your children are very young, they have access to information from online sources. The best way to handle a concern in the news that is not going away any time soon, is to provide credible, age-appropriate information for your child. 

The internet is full of alarmist rhetoric and false denialist statements. Studies show that people are more likely to click on headlines that make outrageous claims. Be careful when these are about scary science. Beginning as early as it makes sense, talk to your children about how to evaluate and vet the sources they use for information.

4. Discuss Science Successes

As a part of science literacy, learn about science successes. Learn how we went about enacting change to shrink the ozone hole, which was another manmade science crisis. Research the development of the smallpox vaccine and how the deadly smallpox virus was eradicated. Study the Southern White Rhinoceros that was delisted from the Endangered Species List. Learning about science successes is an important step in empowering children to be the change they want to be in the world. When they learn about the successes of others, they can see how they too can be a part of the solution to fixing scary science.

5. Take Action

Taking action is an important step for people who are scared or angry about an issue. You might feel these science issues are too big for you to solve through your actions alone. You are probably correct. This is worth discussing with your child if they feel that way. The flip side, however, is that by not doing anything, they are not part of the solution. And for young people who are scared, it is empowering to feel they are doing something to address their concerns.

Talk to your child about how they want to take action. It is important they feel ownership over the activist work they do. When you teach your child to act on issues they are concerned about, you are teaching them a far-reaching lesson. You are teaching them how to deal with “scary” issues in a positive way. You are teaching them to show up and use their voice. Together, that is how we can solve scary science.

Empowering Your Child with Science Knowledge and Positive Action

Navigating tough science topics with kids can be challenging, but by using these homeschool tips, you can approach these discussions with confidence and empathy. When you prioritize science literacy, provide credible resources, and celebrate science successes, you help your child replace fear with understanding. Encouraging them to take meaningful action, even in small ways, empowers them to see themselves as part of the solution. With patience, openness, and these homeschool tips, you’re equipping your child to face “scary science” with resilience and hope for the future.

Handcrafting High School: Year 1, The First Four Months: Science

Science: A Parent’s Passion

        I LOVE science‼ My son likes science. This is the main area of handcrafting Sean’s education that has focused on the passions of someone in his family besides him. (My husband’s and my other passions are shared by Sean.) I am a scientist, and I know a lot of science. Even though he doesn’t have my strong passion for science, my son is good at science. He has had the benefit of a good science education. I am a passionate proponent of people learning how the natural and physical world works. I do not think of science as an ancillary subject, and I believe strongly that the treatment by our academic institutions of science as ancillary has led to a lot of the problems our world is facing right now.

Stars are being born here. This is from the Hubble Telescope. It is easy to understand how captivating it is to study astronomy.

I want to come clean with you; I did something I caution other parents against doing. I am using my middle school science textbook for high school. I made sure Astronomy and Earth Science was far enough along so that I could use it with Sean this year. Let me start by telling you, it is a middle school text. I am beefing it up by adding more math to it, having him write regular lab reports, and having him read relevant periodicals, books, and on-line articles to go along with the weekly theory, but I am not significantly changing my text. I am calling this course Applied Chemistry and Physics, which it is, on Sean’s high school transcript to make it easier for the colleges where he applies to recognize the coursework this class entails.

It might make me sound a bit like a control freak (I am not btw), but here are my reasons for using my text even if it is a middle school text. My choices of texts and courses are severely limited when it comes to those that are sold to the homeschool community because:

  • I will not use a course that excludes or misrepresents scientific facts, principles, models, or theories that are considered core ideas in the field. I am a scientist. I am not going to play silly games about what constitutes good science. I care too much about it. It pains me to admit it, but most of the science materials developed specifically for the homeschool community play this game of omission and/or misrepresentation with many of the core established understandings of science. When I see this it is a signal to me that the person responsible for the material does not have the same passion I do for teaching people how the natural and physical world works, and I just cannot use their stuff.
  • I find many public school texts available for homeschoolers to be dry, arcane, and full of advanced topics without enough grounding in the foundational fundamentals.
  • Many texts have an inadequate or thoughtless pairing of labs with the theory.
  • Often with public school texts, there is just too much material to get through in a year, with too much emphasis on facts that could easily be looked up using your phone (which is what we all do!).
  • Most public school texts assume the material is going to be taught by a teacher, so the fit isn’t easy if you are not prepared to teach from it. And even I would rather not put together a yearlong series of lectures for just one student from someone else’s text. That is one reason my texts are written to the student as a really complete series of lecture notes. (That is how I think of my texts.) I consider each chapter in my text to be one (occasionally two) lecture’s worth of material written in a conversational manner. It is also why the Teacher’s Guide has a Text Review. Those would be my lecture notes if I were teaching from my book. It is much easier for me, the author, to write the lecture notes, than for parents who are using my texts.

This does make me sound like a control freak about science doesn’t it?!? LOL!

I have my reasons for using my text, but even so, a year ago it would have made me nervous to use this course for high school. Then two unrelated events happened that made me take a harder look at the science many consider high school level.

  1. I signed Sean up for a science co-op class to take along with this one. The class met the University of California a to g requirement for a high school science class. The class only met once a month! The labs did not seem to be carefully paired with the theory. They felt more like a hodgepodge of laboratory techniques crammed together. I concluded that if this class met the UC System requirements, then we were doing above and beyond that with my middle school courses.
  2. Early in the 2014/2015 school year, I was contacted by a parent who is using RSO Biology 2. They had recently moved to New York State. Here is her statement from a review she wrote about RSO Biology 2 on Amazon, “I’m now using this book to teach a science co-op in NY. According to the White Plains school district, the labs in this book can be used to qualify for the biology/living environment Regents Exam.” In a separate email, I learned that to graduate from high school in New York State you must take certain classes and then pass the Regent’s Exam for those classes. After reviewing the material in RSO Biology 2, the White Plains School District told the homeschooling parent that as long as they saved the records from the biology labs this course would satisfy the high school requirement for a year of biology/living environment. The irony was the parent was not trying to get them to approve this as a high school level course. Her daughter was in middle school. When she moved to the White Plains school district they wanted to look at the materials she was using before giving their approval that she could homeschool her daughter! She shared the topics and labs from RSO Biology 2 to get them to approve this book for use in middle school. Instead the school district approved the book for high school (and middle school). Her daughter and the other students at the co-op are getting credit for both, I guess. there was also a comment in a similar vein from a different reviewer on Amazon. This is a quote from their comment, “P.S. I suppose I should mention that before this program, he scored in the 69th percentile on science (7.3 GE) according to a national, standardized test for fifth-graders. This year he scored in the 90th percentile in science (13+ GE) on the same national, standardized test given to sixth-graders. What does that mean? It means he’s got mastery of the content more than anything.”
RSO Biology 2
Science: RSO Biology 2 http://www.pandiapress.com/?page_id=82

When RSO Biology 2 first came out, people contacted me about using it for high school. My standard response was that it was not written to be a high school level text and there were things that were left out that I would have included in a high school level course. For example, I left out the electron transport chain during the discussion of photosynthesis. I left out a probability exercise showing the number of different combinations of chromosomes that can be made during meiosis and then recombined at fertilization for two diploid organisms with 3 chromosomes in their karyotype. (I did write this though. My publisher wisely had me remove it. It really was advanced even for most high school students. 😉 ) There would be more chemistry woven into the biology. Next school year Sean will study chemistry. I will have to make sure he gets the important biochemistry then.

I spent some time thinking (mildly obsessing my husband and publisher would say, LOL!) about the situation with the Regent’s Exam, and I think I know why the school district felt RSO Biology 2 qualifies as a high school level course. Good science programs are moving away from a focus on memorizing facts and to a focus on science practices. In most cases, the basic concepts and foundational fundamentals are the same for a high school and middle school text. Maybe middle school courses do not check every single box for the more complicated concepts, but there is no way for middle school and high school students to practice most of the more advanced concepts anyway. Very few texts have a strong focus on the application and practice of the science concepts being taught. RSO Biology 2 (and Astronomy and Earth Science 2) have that as a primary focus. There is a focus in these courses on learning the foundational fundamentals and then applying them. A focus on the application and practice of science concepts and foundational fundamentals translates to a focus on using the scientific method in a meaningful way, the way scientists actually use it.  It is one of the reasons I have students make their own slides in RSO Biology 2. If you buy prepared slides, you will get a better view of the specimen than if you prepare your own slides. I guarantee it! But if you do that you will never become good at making slides, and studying science should not just be about looking at what others have done. Studying science should include you interacting with the natural and physical world to come to a better, more complete understanding of how it works.

Science: Lunar eclipse, 10/7/2014

I would have used Astronomy and Earth Science 2 even without these two things happening, but I would have obsessed more, making sure I covered the specific facts I am leaving out of the middle school text that I would not leave out in a high school text. I have a confession to make about last year too. I used my biology text as a high school level biology course in 8th grade. Sean wanted to do biology again in 8th grade. The sequence for Sean’s science during middle school was 5th grade: middle school biology, 6th grade: physics, 7th grade: chemistry, 8th grade: high school biology. He hasn’t had astronomy or earth science since 2nd grade.

So far this has been a great year of science. The sequence of topics in the text is astronomy, geology, hydrology, the atmosphere and meteorology, and environmental science. Sean has only gotten through the astronomy portion. Sean is loving science this year. Astronomy has really captured his interest and imagination. I have to be careful when Sean looks at the supplementary videos and articles, because he can lose a day that way. Not that I mind, it is just that I have to make sure there is nothing pressing when he starts science!

The Parallel Universe Theory has captivated Sean's imagination.

In addition to using my course, Sean has read the following:

A Wrinkle in Time
Science: A Wrinkle in Time
  • A Wrinkle in Time by Madeleine L’Engle – The reading level was a little young for him, but I coupled the reading with a discussion of Einstein’s Theories and how there could be “wrinkles” in time. (A topic that isn’t too young for him or anyone else!) Sean loved this. In addition to his studies, he has taken the time to learn MUCH‼ more than I know about parallel universe theories!
A Brief History of Nearly Everything
Science: A Short History of Nearly Everything
  • A Short History of Nearly Everything by Bill Bryson – This book along with my course, I feel, took Astronomy and Earth Science 2 up to the high school level! Sean has loved parts of this book and been lukewarm about others. I should probably state here, my son will enter college with a level of science that will enable him to do well in his science courses. Sean knows more science than most adults, but most adults do not have much science knowledge. Unless Sean changes his mind, Sean’s focus in high school science will not be at the AP science level. If your student’s focus is at the AP science level, this is not a rigorous enough course for you. But because of the focus on the foundational fundamentals, Sean is able to make connections across the science disciplines that are deep and nuanced

.

The Martian
Science: The Martian
  • The Martian by Andy Weir – I read this book in two days. It took Sean a week. This book is science, science fiction, action, and a nail biter. Each day that Sean read this, I had him email me a writing technique he noticed and liked that the author had used, I also had him email me 1 science fact from the book.

I know many of you want to get your hands on this text NOW!! I am peddling as fast as I can, I promise!

Learning Science

Learning Science, Secular Science Homeschooling

 Homeschooling and Science

A Winning Combination

I am reposting this article in response to an article in the New York Times. There is a link to that article at the bottom of this post.  The article validates what I am detailing below about how science is best learned!

Learning science is something I have spent 24 years working at in one aspect or another. Today I want to talk about what I have learned over these years educating in various venues and to a broad range of age groups. This is the text from a talk I gave at the California Homeschool Network Convention, CHN Family Expo, in June, 2014.

I was a college professor, teaching chemistry and biology at community colleges before retiring to homeschool my son. I also write secular science textbooks for the Real Science Odyssey series. This is a series of textbooks that have been written primarily for use in a homeschool or small co-op setting. As you can imagine, at our house, we definitely take time to learn science. In the school year 2013/2014, these two areas, facilitating my son’s science education and my textbooks, combined when I taught a homeschool science co-op using the REAL Science Odyssey Biology 2 Course I wrote. I learned some things teaching this co-op. I will touch on some of those things today, but if you want more, you should go to my articles in my blog where there is information detailing what I learned about teaching a science co-op for homeschoolers.

First I would like to ask a question. Have you ever had a great science course? If you have, what made it great? I doubt that even one person thought of a science class that only had reading text and listening to lectures! People approach me all the time worried about the job they are doing teaching science. So many people have had a bad experience in school when it came to science. Those same people want their children to learn science but they do not know what a good science course looks like.

When I think about what a great science course looks like, I recognize that the elements for it are best met with the type of environment we have in the homeschool community, whether in our own home or in a small co-op. I’ve come to understand that the homeschooling environment is absolutely the best environment for learning science.

So how can I say this? There are many people, notable scientists among them (Bill Nye comes to mind at the top of the list), who believe the exact opposite.

Of all academic subjects, science is the one that is the best fit for the homeschooling environment. Why? Because science is best taught where there is the time and space to ponder, research, explore, and get up and experiment. With the right tools and support you don’t need a science degree either. All you need is a willingness and desire to have your child learn how the natural and physical world works.

Start early:

  • Serious subjects are taught beginning in grade school.
  • Why isn’t the subject that teaches how the natural and physical world works serious enough to start teaching early?
  • Starting early allows for more depth and complexity.
  • I hear from people that they can wait to teach science, that kids are not ready to be taught science in grade school. I don’t understand the logic behind this. Science explains how the natural and physical world works. Why isn’t grade school the perfect time to begin teaching science? It’s sad, because kids want to know about plants and butterflies, stars and planets, how cooking works, atoms and energy. Young children are fascinated by these things. I actually think a big part of the problem with science education is that parents are not fascinated by it anymore, and it’s really a shame. Adults are not fascinated by it because their science education was so poor. We as homeschoolers can change that.
  • Recently I volunteered at the Intel International Science and Education Fair, the Intel ISEF. It is a huge international science fair. They consider it a science talent search with thousands of high school students from across the globe competing for a total of $4 million in prize money. I always enjoy myself immensely at these gatherings because it’s the only time I get to sit around with a whole bunch of scientists and talk science. At lunch time I happened to sit down with 6 female scientists. Three of them were, or had been, high school science teachers and one was a community college teacher who taught people how to teach science. We all got to talking about what we did or had done and of course it came to homeschooling science when they wanted to know what I did. It was very interesting. You might think this group would not be proponents of homeschooling. I did. You and I would be wrong. These women had been to many science fairs as volunteers and what they saw, again and again, was that increasingly often the best science fair projects were from homeschooled students. I was told that more often than not the homeschooled kids are the ones that win the science fairs. I was curious to find out why they thought homeschooled kids were doing a superior job of learning and experimenting with science. They said to me that the problem stems from when traditional schools begin teaching science. According to them, science is being taught later and later in schools. This is due to the current state of public education and the testing which affects a school’s funding. Schools pour time and money into language arts and math, because if test scores are low in those areas a school’s funding is cut.
  • Teachers focus all their energy and resources on math and language arts to the detriment of science. If kids are lucky enough to get science before high school it is as a component of language arts. It isn’t science for the sake of science. Now this touches on several things I want to talk about in a minute. But when science is a component of language arts, it’s about reading science. It’s not about doing science and there’s a big difference. It’s why a lot of adults think science is boring. So what happens when you don’t start science until high school is that you have students who come into high school weak in science. Therefore the science teachers have to start teaching at a much more basic level then they were teaching in years past.
  • If you’re curious to see the difference in levels, go to the Pandia Press website and look at the difference in REAL Science Odyssey Life 1, Chemistry 1, and Biology 2. RSO Life 1 is written for early grade school, Chemistry 1 is written for late grade school, and Biology 2 is written for middle school. You can look at them in the ‘Try It before You Buy It’ section. I really encourage you to look at them side by side. I encourage you to compare the two biology texts and to look at the progression within these books. There’s a big change. There’s a certain amount of knowledge that you begin to anticipate and expect that students are going to have. Students who start a new school year with some knowledge have an advantage. This is similar to what is done in math or language arts. You do not want to be teaching high school students phonics or basic spelling chunks. You want to be discussing literature with them.

Focus on the fundamentals:

  • Scientific Method
  • Good Foundation means a good grasp of how the various pieces relate
  • Good Foundation allows for a better understanding of new concepts
  • Good Foundation leads to a better ability to analyze data, models, and theories about how the natural and physical world works
  • When I talk about fundamentals, I am talking about the underlying principles that are the root knowledge required for a more advanced understanding of a subject. These are things that high school students in traditional schools are no longer coming into the science classroom knowing.
  • Scientific Method: An important aspect of learning science is learning how to use the scientific method. Using the scientific method depends on knowing the basic facts of science. The absolute best way to learn the scientific method is through applying it. The scientific method is based on experimentation, observation, and deductive reasoning. One reason that the homeschool environment is superior is because homeschoolers are given the time and space for experimentation, making observations, and deductive reasoning. It really is the best environment for learning science. Teasing out the answer to a problem is not something you can set a time limit for accomplishing. Schools, by their very nature, are forced into giving students time limits to learn and apply science concepts.   This doesn’t lend itself to a practical understanding of how the scientific process really works.
  • A solid foundation in the basic fundamentals of science will result in students who have a good grasp of how the various pieces in science relate, which leads to a better understanding of new concepts. A strong focus on the foundational fundamentals also leads to a better ability to analyze more complex data, models, and theories for how the natural and physical world works
  • There are certain fundamental principles that are the basic building blocks for understanding science concepts. For example atoms; all matter is made of atoms. Every single science principle where we explain how the natural and physical world works at its core is talking about atoms. Even a graduate student studying complicated scientific principles and theories must understand the basics of atoms. An understanding of atoms is one of the foundational fundamental principles in all of science and is necessary to understand how other pieces of scientific information relate.
  • I think it is a problem that often there is not a focus on the basic fundamentals for two reasons. The first is that the students’ knowledge base is not complete. The second thing I see happening in middle school and high school texts and classes is that concepts that are too complicated are brought in before there is an understanding of the underlying principles. This leads to spotty knowledge which results in people thinking they’re not good in science when it is actually the quality of their education that’s not good. In these situations, some students will learn the new material, but most students will just breeze right over it. I like to use foreign language as an example here. If you’re sitting in a restaurant and you overhear someone speaking a language you don’t know you tune the speaker out. But if you know a little of that language you will listen, try to understand what they’re saying, maybe even start a conversation with them. It’s the same thing with science. If I start talking about polarity and water molecules and you don’t even understand the basics of what a molecule is, you don’t know what I’m talking about and your brain glazes over or moves on to something else. If you do have some knowledge of molecules and polarity, you will pay attention and engage in the conversation, adding to your knowledge base.

Learn each discipline as a single subject:

  • Does not create artificial boundaries
  • Allows for an in-depth understanding of the foundational fundamentals, instead of a “Jack of all Trades, Master of None” approach
  • Mastery of each science discipline is superior for that discipline and for making connections across disciplines
  • On the face of it, it might sound like spending an entire year every four years on a single subject creates artificial boundaries between science disciplines. While it is important that the material you use to teach points out and makes connections between the different disciplines, the best approach is to learn the fundamentals of each discipline and make connections once the basics are understood. This creates a cohesive body of knowledge which enhances a student’s ability to make connections between the disciplines.
  • Often science is learned with a grab bag approach, which I call the smattering approach. When I told the gals at the Intel ISEF fair that I was not a fan of the smattering approach they said that in the past they would have agreed with me. But that now, the state of the science being taught is in such a shabby state that they would even like it if people went back to the smattering approach. It turns out that the smattering approach for learning science is better than not learning it at all. So I guess if it’s between the smattering approach and nothing at all, the smattering approach is okay to use. Otherwise, any good science teacher will tell you you’re better off teaching science as a single subject, just as we do every other academic subject we care about our children learning.
  • This really goes back to teaching the foundational fundamentals. You start to build on concepts, creating a firm foundation, adding more and more complicated material on top of it. Anyone who has worked with their child in math knows exactly what I’m talking about. There is no other subject that we take seriously that we do not teach as a single subject. There is a reason for that.

Rely on one or more good textbooks:

Real Science Odyssey Biology 2
RSO Biology 2 http://www.pandiapress.com/?page_id=82#level2
  • Comprehensive
  • It helps to have a guide, someone who is an expert in that field, to help you figure out the scope and sequence of the material to cover.
  • Different students access information differently.
  • Focus on the fundamentals.
  • Make sure the text is secular teaching the theories and models that are central to each science discipline.
  • Don’t teach a co-op class without a text.
  • I write science textbooks that are long and complete. I do not write fluffy science. So it should not surprise people that I am a fan of having some sort of guide and guidance to follow for each subject that I’m having my child study over the course of the year. I learned my lesson with first grade biology that even someone who is very knowledgeable in the field could use some direction. When I homeschooled my son in first grade I had a guide and reference material for every subject he was learning, except biology. I thought, “How hard will it be? I taught biology at community college. I have a biology degree from UCSD. Biology is going to be a piece of cake.” It turns out, with all the other subjects he was working on I was overwhelmed when it came to planning and figuring out a course of study as I went along. In fact, when my son was in second grade I had him work through RSO Life 1 and Earth and Space 1!
  • I will be honest; my reference material is not always a textbook. In history we use video courses and material where someone else has put together a complete package. Science is a little different than history though, because you are still going to need lab sheets, material lists, and I really think it’s good for students to be able to read the information if they need it.
  • Choose texts that are comprehensive and do not skip over the basics, introducing advanced topics and language with a focus on the fundamentals. I do not think it matters which science discipline you start with, but I would suggest waiting until 3rd grade for chemistry and physics. When your child is ready for their multiplication tables they are ready for chemistry. It has to do with the abstract nature of chemistry.
  • Every area of science has a lot of information to it. It helps to have a guide, someone who is an expert in that field, help you figure out the scope and sequence of the material to cover. I believe there is no way to teach the foundational fundamentals or to teach science as a year-long single subject without a textbook. In every science class I have ever taught, I have been handed a stack of textbooks. I was given the teacher’s textbook, the lab manual, the answer key, and test making software, because a committee of people at the community college where I was teaching decided that was what the course was going to look like that year. Perhaps this sounds limiting, but I did not find it so. You can use the textbooks as a touch point if you want, but it is essential to have a guide so that the material is covered in a complete fashion.
  • The other important thing about having a good textbook is that students access information in various ways. I learned how important it is to have reference material when I taught a co-op class this year. Based on my experience, I wouldn’t have my son take a science co-op class if there wasn’t a textbook because if the subject gets complicated your child needs something to reference, not the Internet either. I think it is important to have something they can hold in their hands, something they can underline, highlight, and make notes from. A source that you can both go to.
  • Along the lines of accessing information I’ve actually been thinking about making some videos for my text and putting them on my blog for kids who are struggling with some of the more complicated concepts. The genetics unit in my biology textbook, for instance, is an area kids find very difficult. I think if students had me lecture out of the book to them, those kids who were feeling challenged by the concepts would be able to understand the information better. I’m very into making sure there are multiple ways to access information.

 Carefully pair theory with labs and activities

  • All theory and no labs, what a bore
  • All labs and no theory, teach cooking instead 

Let’s be clear about what I’m talking about when I call something a good science course. I am not talking about sitting in your seats. I am talking about getting up and moving around, getting your hands dirty. I’m talking about taking those foundational fundamentals and applying them to real-world labs and activities that relate well to the theory. This is where science becomes fun.

  • When scientific theories are paired well with labs and activities it enhances an understanding of the scientific method and science learning. It demonstrates through use and practice how hypotheses are formed and conclusions determined based on science facts that are presented in the text.
  • Sometimes I see science being taught where it is all theory with no labs or activities. The science theory is the science information in the written text. Other times I see science being taught with all labs and activities but no theory. Neither is adequate.
  • Honestly all theory with no labs and activities, why bother. That’s where science gets a bad name. For parents I know that the labs and activities are work. I know you do not always feel like setting them up. I know this because I teach my child science, and I don’t always feel like setting them up, but I do it because it’s important to me that my son gets a good science education. A good science education has labs and activities that are carefully paired with the text and theory.
  • All lab and activities with no theory might be fun, but you are not learning science cohesively. You’re not learning the foundational fundamentals. For example, how many of you understand the complicated process that occurs when you bake a cake? By this I mean the physics and chemistry involved in the baking process. To bake a cake you don’t need to know the underlying science because that is not your reason for baking it. It is about making a yummy treat for your family. In order for it to be called science you would need to understand the physics and chemistry of the process. And to know and understand the science you need to have studied the theory and then done the experiments. That way it all ties together.
  • When this is done; the pairing of the theory with the labs and activities, no place outside a college lab that is thoughtfully paired with a lecture course can match the homeschool community. It might be another reason why we are winning all of those science fairs.

5 Steps to a Great Science Education

  1. Start Early
  2. Focus on the Fundamentals
  3. Single Subject
  4. Good Textbook &/or Reference Materials
  5. Carefully Paired Theory and Labs & Activities

I hope that this helps any of you who are worried about your children’s learning of science, and that this doesn’t sound complicated to you. All you need to facilitate your child learning science is a desire and the resources to make it happen. I want to close with, “Science is so much fun to do, to share and interact. I really hope you take the time to explore science with your child. Who knows, maybe the next time someone asks you if you have had a great science course you will raise your hand, because the years of science you did while homeschooling your child were just that good!”

Update: In December of 2014 the New York Times published an article about college reinventing how science is taught and better learned using the principles and methods I am advocating here!
