Instructions

In small groups of 2-4, your challenge is to find the most accurate method for measuring a 10-second interval.
You have three options:
- Rolling a marble down a ramp
- Sand flowing from a paper cup
- Water flowing from a paper cup
1) Choose your approach and explain why you think it’s the best. You have 10 minutes to set up and test your equipment, but the timers will be removed after that.
2) Prepare your equipment. The adult will signal when to start. When your device reaches 10 seconds, one team member should raise their hand. The adult will announce the closest group.
