This stem challenge involves student teams designing, building and testing a catapult that will shoot a marshmallow towards a target.
This set includes teacher notes, a 6 page printable lab booklet for students to use as they perform this task, stem role cards, stem step posters and a rubric. I have designed this as a winter stem activity in which the problem involves students building the catapult to use during a snowball fight. I have also included another problem sheet to be used at any time of the year.
