Static Electricity: What's Attracting?
Medium
Ever been shocked by static electricity? It's created when electric charges accumulate on the surface of a body. In this experiment, you'll rub a balloon on different materials and count how many pieces of paper it attracts.
Hypothesis
The hypothesis is that human hair will have the highest amount of static electricity.
Method & Materials
You will connect a copper plate to a ground connection, cut a sheet of paper into small pieces, inflate a balloon, and rub it on different materials.
You will need a balloon, copper plate, ground connection, jumper wire, human hair, polyester cloth, carpet, cotton cloth, nylon cloth, ceramic tile, flat tray, ruler, sheet of paper, and paper knife.
Results
The results showed that different materials had different amounts of static charges. The balloon picked up the highest number of paper pieces after being rubbed against the hair.
Why do this project?
This science project is interesting because it shows how static electricity works and how different materials can have different amounts of static electricity.
Also Consider
Consider repeating the experiment to see how much the balloon will “pull” or attract a small stream of water flowing from the tap. Also, try using a comb instead of a balloon.
