Investigate science in winter, spring, summer, and fall!Teachers and kids will never be at a loss for what to do with this treasure trove of fun experiments, projects, and facts for every season. In this brand-new book, Janice VanCleave presents an experiment for every week of the year, on dozens of topics in astronomy, biology, chemistry, earth science, and physics. Kids can discover why leaves turn colors and fall off trees in the fall, why September is a good time to look for monarch butterflies, how salt melts ice, what pine cones can tell you about the weather, and much, much more. As with all of Janice VanCleave's science books, the activities are fun and easy to do with step-by-step instructions and common materials.
