U3b-L9
“TOP THIS” Design Project
Listen to instructions first, then get in action:
Get your top and get into groups of 4.
Designate a recorder and a reporter.
Take turns spinning tops (you each get 3 spins total)
The recorder times each spin and records it on a clean sheet of paper.
When time is called (~5 minutes), reporters will report the longest-spinning top of the group.
In front of the class, these top spinners will compete with 3 spins each.
