Trebuchet Toss

This Trebuchet Toss lesson plan also includes:

Young engineers work in teams to design and build their own trebuchets according to certain criteria; they must be able to launch a mini marshmallow accurately into a pie tin. Background reading material, a planning sheet for trebuchet design, and evaluation questions are all provided for your class. This would be an ideal project to hold in science class while students are learning about the Middle Ages in their history class!
