What Kids Do:
This might be the most fun WonderWorks class we've ever had. There was so much giggling and delight going on the entire time, from both kids and adults. EVERYONE loved this project! I gave them a few springy tools, some levers and instructed them to choose only lightweight projectiles (pom poms and packing peanuts mostly). Here are a few of the catapults they came up with.
Hindsight Tip: Although more families might have packing peanuts at home than pompoms, the younger children in the room loved just crumbling them to pieces. Next time, I think I'd add cotton balls as my second option if one is needed.
Variations to try:
instead of pompoms, you could also try using packing peanuts, cotton balls or marshmallows as projectiles
Here are some more elaborate catapult plans: from popsicle sticks, from a paper clip, paper towel tubes and a wooden spoon, from two pieces of wood, popsicle sticks and a plastic spoon, tissue box + pencils + rubber bands and a milk cap, soup can + piece of cardboard
Related Apps: There are lots of catapult-related apps available, but most of them are violent, and I'm not sure if the physics of catapulting really come across in an app, so I hesitate to recommend any here.
