Each volume in the series focuses on one major area of science normally taught in grades K-8 and offers a store of stimulating activities that can be used with virtually any science text. All activities are complete and ready for use. Book III presents over 165 inquiry activities covering the topics of Air, Water, Weather, the Earth, Ecology, Above the Earth, and Beyond the Earth.
I purchased all three of the science activity books to help fill in a homeschool science program. I think I could probably use these books alone as a science program. These are great experiments with enough background for the non-science person to teach from. They use largely materials that you have lying around the house, and when they ask for something less available, there is often another experiment with more common items that teaches the same concept. Very adaptable to the multi-age classroom that most homeschoolers have. It's very easy to make the lessons harder for older students while not "losing" the Kindergarteners.
