101 Science Class Ideas for Homeschool Co-ops

This post was inspired and sponsored by Air Is Not Oxygen: Essential Science You Should Have Learned … But Probably Didn’t!. Opinions are my own and I was not required to write a positive review.
If you are part of a homeschool co-op, you probably help come up with class ideas and titles. Maybe you have to teach a subject that wouldn’t be your first choice. If you’re planning your next year already, like our is, you might need some inspiration. So today I’m sharing a list of Science class ideas. Some are subjects, some are titles. This is just to help you get those creative juices bubbling. I’d love to hear your ideas for Homeschool Co-op Science classes, too, so please share your ideas in the comments.

Homeschool Co-Op Science Class Ideas

biology topicsBiology Classes

1. The Human Body.
I love Exploring Creation with Human Anatomy and Physiology (Young Explorer Series)from Apologia for teaching this course but there are really so many great resources, both free and paid, for this subject.
2. The History of Medicine. A possible text for older students:
Exploring the History of Medicine
3. Biology. Our co-op is using Apologia’s textbook:
 Dissection is one of those things I’d rather have happen at co-op than at home!
4. Health. Most high school students need a Health credit, but it could make a fun class for younger students too.
5. Nutrition
6. 1st Aid & Safety

botany topicsBotany Classes

7. Gardening – think of the fun of a community garden plot, or you could do an indoor gardening class.
8. Green Thumbs. One fun book to consider:

9. Leaves & Trees
10. Bloom & Grow (Flowers & Trees)

astronomy topicsAstronomy Classes

11. Space Fun
12. Stargazer’s Guide to the Universe. One possible text:

101. Air Is Not Oxygen: Essential Science You Should Have Learned … But Probably Didn’t!
As I mentioned in my disclosure above, this post was inspired by the book Air Is Not Oxygen by Dr. Bill Morelan.

Why Did Air Is Not Oxygen Inspire This List of Classes?

Because as I read through it with my oldest daughters I immediately thought about how perfectly it was laid out for a co-op type setting. There are almost exactly the right amount of chapters for a two term co-op (12 weeks in each term) like ours.

The major divisions are:

  • Physical Science
  • Life Science
  • Earth & Space Science

Each chapter is brief, witty, has several experiments using readily available materials, and meets current national standards for Science instruction. There are bonus investigations at the end of the book (titled Related Science).

I loved that the experiments don’t call for items I’ve never heard of or can’t get easily. The author’s tone is fun and the chapters are short so it never feels like information overload. Vocabulary is concisely explained and the author doesn’t talk down to the reader. There are fun quotes throughout and I especially appreciated his epigraph where he tells the student to put down the book and go outside. I sometimes wonder if we wouldn’t have so much panic about “STEM” education if our children played outside more. Science begins with what you observe and kids aren’t observing as much as they used to. [OK, sermon over. Couldn’t help slipping into “Back in My Day” mode there for a minute!]

Dr. Morelan has been a “Teacher of the Year” in two states but he is also a pioneer homeschooler who taught his daughters at home in the ’80’s. This gives him a great perspective on teaching Science, whether in a classroom or home setting. Because isn’t it nice when you know an author has real experience?

I hope this post has given you some ideas for your homeschool or homeschool co-op Science classes. Pick upAir Is Not Oxygen, work through it a bit at a time with your kids, and then go outside!
