Great Science Fair Ideas

Why doesn’t the Moon fall to Earth? Why do the seasons change? What is parallax? How can you simulate weightlessness on Earth? Young scientists will explore the solar system through applied space science answering questions about space. The far-out space experiments in this book will help students make a model of a lunar eclipse, build a spectroscope, and more. Many experiments include ideas students can use for science fair projects.
