Do you want to make the best paper airplane? Or perhaps centripetal force and the idea that water can defy gravity excites you! This is the book for curious young physicists, ready to learn more about the world around them. Each of the 10 projects includes a Background section to explain the science topic at work, materials, clear step-by-step instructions, and an Observations section walking readers through the results they likely saw. Several projects include science fair ideas and expanded versions of the experiment to engage readers further. A discussion of the scientific method and helpful glossary conclude the book.
