Straw Rocket Activity
The balloon is made of rubber and has shape that it prefers. It will return to that shape when it can. When the balloon is inflated, the rubber is stretched way past where it wants to be. As soon as it gets a chance, the rubber will push the air out of the balloon and return to its original shape.

Pre-Assessment/Invitation to Learn
Tell students the balloon is lazy. It likes to stay flat and lifeless. Have a volunteer blow up the balloon. Ask the students what the lazy balloon wants to do. Does it want to return to its lazy state? Tell the students that they are going to get a lazy balloon to do some work before they let it resume its flat, lifeless state.
Homework & Family Connections
Have the students make a straw rocket at home.
Did the students complete the Balloon Rocket Observation Log accurately? Were their predictions accurate as they filled out the chart?
