"Oh no, A meteorite is headed toward Coyote Club! Invent a machine that will catch the meteorite and send it back into space."
After giving each team a random scenario, they brainstormed ideas of what they could make. Once they had an idea of what to make, they grabbed their craft supplies off the supplies table and went to work. I gave them about 30-40 minutes to engineer their product which the groups showcased to each other at the end.
Overall, this activity was so much fun! The kids were able to work cooperatively, negotiate, and developed some public speaking skills by getting up on the stage and presenting their work to the group.
