My high school biology class started working on an elementary science standard to kick of the school year: Design Problems. We are using this standard to teach the students about the Scientific Method.
Define the Problem
Which student can build a catapult that will shoot the marshmallow the farthest?
Do Your Research
We researched different designs on the internet. We printed pictures and passed them to the group leaders.
Develop a Possible Solution and Design a Possible Solution
Each group decided on a marshmallow catapult.
Build a Prototype
The students created the catapults. I am not quite sure who had more fun creating these catapults, the adults or the students. There was some competition going on in the classroom!
We tested the catapults and measured their distance to compare them. We did this in the hallway. It was quite the challenge for the students to pull the spoon back, keep the marshmallow on it and then release. Most of my students needed assistance in completing this task. (… and yes, we also used the catapult to shoot a marshmallow into an adults mouth.. only worked once ;-))
