What are the forces behind ballistics? Why do rocks and rockets soar through the air in an arch?The game is on the line. Suddenly, you hear the crack of a bat and the roar of crowd. Where will the ball land? How far will it travel? Is it a home run?You might think that hitting a home run or nailing a three-pointer is just luck, but there are many forces at work that determine if you?ve made a game-winning shot or the final out. If you?ve ever kicked a ball, thrown a rock, or even played Angry Birds, you?ve experimented with the forces behind ballistics.In Ballistics: From Rocks to Rockets with Science Activities for KidsMath is the language you use to understand the science of ballistics. In this book, readers will learn about the forces that act on the projectiles and how to calculate those forces to make educated predictions about where their homemade rockets and other projectiles will land. Safe, hands-on STEM activities using materials that are easy to acquire are a terrific way to foster real-life learning about ballistics. Kids will perform Galileo's famous test for gravity, create clinometers to measure height and distance, and build a machine that can throw curve ba...
