I prepared five kits with materials to build a catapult. One kit had clothespins, a popsicle stick, a spoon, and rubber bands. One kit had seven pencils, a spoon, and several rubber bands. Another kit had certain LEGO bricks. One kit had seven popsicle sticks and several rubber bands. There was a kit that had certain K'Nex pieces. The K'Nex kit is the only one that was allowed to be modified.
|Inspiration for the STEM activity|
The students were put into five groups. They were told that they could only use the items in their kit. One person in the group used their Chromebook to research how to make a catapult using the items in their kit. We talked about what the letters in STEM represent. We also discussed the STEM process. I told them that once they were in their group, I would no longer be available to answer questions. They would have to rely on each other to solve any problems they might have. That was harder for me than it was for them. Any questions for me had to be addressed before they got in their groups.
