Introduction: Why did ancient humans develop methods of sending projectiles farther, faster? How did this ability make life better?
Chapter 1: What are the different forces that control movement, and what would life be like without these forces?
Chapter 2: When might it be useful to know the height and distance a projectile has traveled?
Chapter 3: Why do people keep inventing new and improved ways of sending projectiles through the air?
Chapter 4: What are some different ways of manipulating the motion of a projectile through the air, and why are these useful?
Chapter 5: How are rockets similar to pebbles shot with a slingshot? How are they different?
