Yesterday we began looking into static electricity and found that it is a single, sudden transfer of electrons from on place to another. Lightning is a form of static electricity! And when we get shocks from doorknobs or the metal screws on the slide of the playground!
We did our first lab experiment. We built up an electric charge by rubbing balloons on our hair or on the carpet. The rubbing makes the balloons pick up electons from our hair or the carpet, giving it an electric charge. We then tried to see if different bits and pieces of paper would attract to the balloon.
Take a look:
What kind of charge does the balloon have after we've rubbed it against our hair?
What charge do you think the paper had that stuck to the balloon?
Why?
