Depending on the Physics edition you're using, Module 4 or 5 is about projectile motion. I like to begin with a lab, a hook for the material. We're starting this unit next week with catapults.
This projectile project is the basis for the catapult lab. Here's how we are going to conduct the lab. The guys will build catapults to address both of the questions below. I have large and small craft sticks, rubber bands, protractors, rulers, plastic spoons, marshmallows, and a glue gun. I'll post examples of catapults on to the TV screen in the Maker Lab at the library. The kids are welcome to use
printed instructions to construct the catapults. My husband, Rob, was alarmed, 'This could take the entire class!' Actually, it might take two classes. But, then, Rob can use these catapults or
the mighty missiles when he does the formal instruction of the module's materials. I'll let you know how it goes.
Quick update:
Physics 40 has detailed calculation examples we're going to use once the guys make and test their catapults.
Scroll down the page to see these questions '
Select one of the following questions
• How does changing the angle affect the initial velocity and range of the projectile?
• How does changing the length of the arm affect the initial velocity and range of the projectile?'
