Static Electricity Data Sheet
Student Activity #1 - Can neutral objects attract non-neutral ones?
- What happened when you put the balloon
near the cereal and paper? Was it any different for the side of the balloon
with the dot?
- Could you get the balloon to stick on all of the different types of walls?
How about the part of the balloon not near the dot?
- Did the balloon attract the water near the dot? Away from the dot?
- From these experiments, what can you say about how charged objects affect
regular neutral objects like paper, walls, and water?
- Why did we pick less heavy things like paper and cereal in our test rather
than something heavy like a pen or a pencil?
- After all of your observations, do you know now whether charged objects
can attract neutral objects?
Student Activity #2 - The Balloon Electroscope
- Why did the balloons repel each other after they were rubbed all over with
- What would have happened if we rubbed one side of the balloons instead
of all over?
- Why did the balloons fall back towards each other after they were sprayed
- What effect does damp weather have on electrical charges?
- During which time of the year would it be best to do experiments using
Student Activity #3 - Static Electricity with Salt and Pepper
- Explain what happens after you rub the ruler.
- Why does that happen?
- Why did the pepper jump to the ruler before the salt?
- Can you think of other ways to separate this mixture?
