EXPERIMENT: STATIC POWER

Materials:

- Sugar

- Salt

- Pepper

- Pen

- Piece of wool

- Small plate

Procedure:

1. Stroke the pen with wool to give it an electric charge

2. Put small amounts of sugar, salt and pepper on a plate. Do not mix

them together. Beginning a few inches above the plate, move the pen

close to the particles. Observe to see if one type of particle reacts

before the others.

3. Record your observations.

4. Repeat the experiment with salt, sugar and pepper mixed together.

Conclusion:

1. Are the particles attracted to the pen at different heights above the

plate?

Yes, they are; I observed the

attraction between the salt and

the pen began to greater

heights than observed with

sugar.

2. Can you separate a mixture of salt, sugar and pepper using static

electricity?

Yes, I can, because the particles was attracted by the pen at different

heights.
