Hello fellow scientist! This month in Super Science Lab, we did weather experiments! We made a cloud, made fog in a jar, and created lightning! We also made rain gauges.
In case you missed it, here is how you can make lightning (warning– this experiment will shock you):
Experiment: Make Lightning
- Push the thumbtack through the center of the aluminum pie pan from the bottom.
- Push the eraser end of the pencil into the thumbtack. (The pencil becomes a handle to lift the pan.)
- Put the Styrofoam plate upside-down on a table. Rub the underside of the plate with the wool for one minute. Rub hard and fast!
- Pick up the pie pan using the pencil “handle,” and place it on top of the upside-down plate.
- Touch the pie pan with your finger. If you don’t feel anything when you touch the pan, try rubbing the plate again.
It’s all about static electricity! Lightning happens when the negative charges (electrons) on the bottom of the cloud are attracted to the positive charges (protons) in the ground. The resulting spark is like a mini-bolt of lightning.
I hope to see you next month. We will be learning about the OCEAN on December 10th at 1:30 pm. Registration opens on November 26th at 9:00 am. Please have your library card ready when you call or come to the desk.
