This page lists additional resources to supplement R.E.A.L. Science Odyssey Life program. The program is great for grades K-2, although it says it’s for grades 1-4. The program is very well put together and super easy to implement. However, some of the books are hard to find now. I decided to make an updated book list of books that are current and easy to find. I’ve also listed additional resources that compliment the program well.

I’ve listed BrainPop videos, which does require a subscription. BrainPop Jr is suitable for grades K-3, and BrainPop is for grades 3-12. We still enjoy watching the regular BrainPop videos though.

Unit 1: What is Life?

  1. What’s Alive? (Let’s Read and Find Out Science Stage 1) by Kathleen Weidner Zoehfeld – Simple book suitable for Pre-K-K ages

Unit 2: The Cell

Unit 3: The Human Body

You may want to pick out just one or two of these four human body encyclopedia type books depending on the age of your child. All of these resources will be used for the next nine units.

Additional helpful books/videos about the human body

Unit 4: Skeletal and Muscular Systems

Unit 5: Circulatory System

Unit 6: Respiratory System

Unit 7: Digestive System

Unit 8: Nervous System

Unit 9: Growth and Genetics


Unit 10: Five Kingdoms of Living Things

For the studyof the Animal Kingdom, one of these encyclopedia type books is suggested. RSO lists Usborne Illustrated Encyclopedia of the Natural World, but it is out of print. I did find a used copy, so I’ll list it last on this list.

Unit 11: Animal Kingdom

Since this unit just deals with making your Animal Kingdom book, I’m taking this time to introduce invertebrates, of which the next 7 units cover. There is an entire series of 28 books on Invertebrates (all released in the past few years), but they are relatively expensive. I’ll list them in just one link, and I suggest heading to your library and seeing if they carry these books. Our library system carries most of them.
