How does Static Electricity work?
Usually, an atom has an equal number of protons and electrons. Electrons have a negative charge of electricity and protons have a positive charge of electricity. Opposite charges attract, so when materials rub together and one material becomes negatively charged and one is positively charged, static electricity results.
To demonstrate the effects of static electricity. What will happen if we charge a balloon by rubbing it in our hair, and then hold it over tissue paper wings of a butterfly?
Supplies you will need:
- tissue paper
- cardstock paper
- googly eyes
- glue stick
When we rubbed the balloon onto our hair, electrons were lost from our hair and gained by the balloon giving it a static charge. When the negatively charged balloon gets close to the positively charged tissue paper they are attracted to each other, and the pull of attraction is so great that the lightweight tissue paper moves toward the balloon.
This experiment is obviously not limited to only preschoolers. My 9 year old son had a great time experimenting with the balloon and butterfly. He was a little more controlled in his movements so I was able to get a couple better pictures.
This post is part of a collaborative Creative Preschool series where 4 bloggers and myself have joined together to bring you fun crafts and activities based on a common preschool learning theme. This week we are sharing ideas focused on Science Experiments.
