Newton’s Law (Third Law)

“Balloon Rockets”

Materials for the Balloon Rockets Experiment:

* balloon

* drinking straw

* yarn

* paper clip

* scissors

* masking tape

Procedure:

1. Untie the yarn to extend the length of the classroom. Leave approximately one meter of yarn slack and then cut the yarn with scissors.

2. Tie one end of the yarn to a support stand. Make sure the yarn is secure and high enough to extend parallel to the floor across the classroom without interfering with objects in the room.

3. Get a drinking straw and use scissors to cut the straw to approximately eight centimeters.

4. Slide the drinking straw piece onto the yarn.

5. Extend the yarn to the opposite end of the classroom. Tie the end of the yarn to another, support stand so that the line is taut and parallel to the floor.

6. Get a long, thin balloon. Carefully blow up the balloon to stretch it out, and then allow it to deflate.

7. Place two 5-cm pieces of masking tape on the straw piece. Place the midpoint of the tape on the straw so that the tape ends extend equally from each side of the straw.

8. Inflate the balloon about ¾-full. Pinch the end of the balloon closed with fingers and twist it several times to seal the balloon, but do NOT tie a knot. Use a clothespin or paper clip to clamp the opening closed.

9. Tape the inflated balloon to the straw, making sure the balloon is balanced, the straw is lined up...
