We started building catapults today. Unlike the Roller Coasters, I actually came into this one with a plan.
This was based on a Science Olympiad problem that required teams to launch an object of unknown mass to an unknown target. That is a LOT of unknowns, so I have given my kids a little more direction.
I want them to build big catapults, but I want them to understand how a catapult works and what kind of plans they are going to need.
So we started off with mini catapults.
That shoot M&Ms.*
You have not lived until your kids have permission to launch candy across your classroom.
Today was the idea day. They got two paint stirrers, 2-4 mini clothespins, one stick of hot glue (I have discovered that this is PLENTY) and a snack pack of M&Ms. Anything else they wanted to use had to be approved by me.
After about three minutes of stunned silence, they took off with this and had a wonderful time trying to figure out how to build their catapult.
I'll give them couple days to perfect their catapult before we have a test day where they have to launch their M&Ms. I'm thinking prizes will be awarded for distance and accuracy.
*Next year, we will shoot marshmallows. M&Ms get eaten pretty quickly and shatter when they hit my floor. I had a lot of explaining to do when the custodian came in this afternoon.
