Students are to work in groups or pairs and design a bobsled. Students will be provided with a toilet paper role, two popsicle sticks, two pipe cleaners, and 1 foot of masking tape. If students wish to brings small things from home, that is okay. Allow students to think through their design. Allow a trial run, and then allow modifications for improvement after the trail run. Hold a final event and display the gold, silver, and bronze winners for this event. This event is fun and engaging. Students really enjoyed it!
