Let’s have some fun with static electricity.
Students are given a variety of materials to explore. Instruct the students to blow up a balloon and see what materials they can get to stick to the balloon.
Possible Questions for Students:
What did you discover about your balloon?
What objects responded to your balloon?
Is there anything you can do to your balloon to make it attract to some of the objects?
Does your balloon ever repel from some of the objects?
How is the balloon like a magnet? (like charges repel unlike charges attract)
Interactive Notebook Ideas
Remember when you’ve gone down a slide and all your hair stands up straight. This is because the friction of sliding has caused a positive charge to be built up on each hair. Since each hair has the same charge, they all try to push away from each other and end up standing up straight.
Likewise, when your skin is charged with static electricity and you touch something metal, like a door handle, the metal is very conductive and will quickly discharge the static electricity, creating a zap or small spark.
