Teams work cooperatively to build a tower made from common items. The tower must be self-standing and hold weight. Teams earn points for the height of the tower, the amount of weight held, and how well they work together as a team. This powerpoint gives teacher and student instructions. Included are a timed schedule, team scoring page, and self-assessment for students.This is a great beginning of school or end-of-school STEM activity. I have used this fun activity in my classroom, and the students always want to do it again.
