Hot Air Mobiles
Create an example car. Use the straws to create an axle for the wheels.
- Slide two life savers or wheels into each straw. Wrap tape around the ends of each straw so that the life savers cannot slip off.
- Connect the two straws center to center using another straw or craft sticks.
- Construct a sail and attach it to the base of the car.
- Give each team four life savers or wheels, set out the remaining materials on a communal table. Show the kids your example car. Tell them their first challenge is to create a car using the life savers and the supplies available on the communal table. Leave your car out as an example.
- Depending on the age of the children you are working with they may need some help. Try to be as hands off as possible, the objective of this activity is to get kids thinking and trying things on their own.
- After each team has successfully made a car that will roll, challenge them to build a car that will travel 1 foot with a simple breath of air. Ask kids to think about sail boats, sail boats are powered by wind similar to their cars. Encourage them to use their thoughts about sail boat in their car.
- As children finish up, bring them to the starting line and have them give it a try. If the car is successful challenge them to move their car another foot. If the car is unsuccessful, ask them to think about what changes can be made to improve their car, have them make those changes and come back and try it again. Repeat until each group has had a few chances to be successful.
