Students designed some sort of transportation that would go down the hill as well as keep their little bunny mini eraser safe inside. We had many trial and error attempts where either the bunny fell out or the mode of transportation fell apart (or both). I was so impressed how the students did not get frustrated when things came apart, but rather picked up their pieces, went back to their table, and started fixing or redesigning. We found that larger, sturdier modes of transportation kept the bunny safe and didn't fall apart opposed to the smaller structures. Engineering for the win!
