The Nature Connection– We’ve used this book as a full year science program. Its broken down by month, so your nature activities are easily planned out for you.

Building Foundations of Scientific Understanding- This book is complete, and very well done. It covers everything your child needs to know to have a solid elementary science education. (versions for K-2, 3-5, 6-8)

These Science kits are inexpensive, and very well done, with clear instructions and explanations of the activities.

Snap Circuits are the easiest way to get kids interested in learning about electricity. If you have a little wiggle room in the budget, I can’t recommend the educational pack enough. It’s all reusable, and worth it’s weight in gold.

For elementary students, Lets Read and Find Out science books can be used as a spine. Each book includes a hands on activity.

Don’t discount the power of The Magic School Bus– We have also used these videos as a core science curriculum, and expanded on the videos with a little reading and hands on projects.

Ellen McHenry has some amazing, creative science programs.
