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.
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.
