2. "Talk and Turn" - After the video discuss the differences between balanced and unbalanced forces.

3. Each person will be assigned a number.
"Jigsaw Puzzle"
Each person will be assigned a number.
Grouping according to your number you will use the information from the QR code to solve either a lift, thrust, or tension problem.
You will then return to your original group to share your information.
