A few weeks ago our STEM Challenge was to design and build a catapult from household items. No kits or legos could be used. The winner was determined by whose catapult could shoot a mini-marshmallow the farthest. Here are a few of the designs.
Our Winning design is Emma (Below). She wanted her prize to be the rest of the marshmallow bag! :)
It is a little hard to see, but this was a launching deck.
Emma's design featured a large plastic kitchen spoon, a shoebox and a few other items to create tension. All participants did a great job!
