Full of Hot Air: Hot Air Balloon Building
In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.
Balloon FlinkerAdd to list Details
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.
Sky Glider ChallengeAdd to list Details
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Balloon DriveAdd to list Details
In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.
Sky Floater ChallengeAdd to list Details
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
