Title of Lesson
Question: This question focuses the inquiry of the lesson.
Prediction: Sometimes the lesson calls for a prediction of the outcomes. Be
sure to state your prediction in this manner: I think that…...because ….. If
science words are used an explanation should follow.
Vocabulary: New words and definitions to be used during the lesson.
Materials: A list of the items you need to complete your investigation.
Procedures: These are step by step instructions on how to complete the
investigation.
Observations: Drawings, descriptions, data tables, graphs showing what
happened during your experiment or investigation.
Conclusion: What did you learn in this inquiry? What were your findings? Be
sure to answer the question posed at the beginning of the investigation. Use
your vocabulary words and definitions! Also check How to Write a Powerful
Conclusion.

Static Electricity (1.e)
Question: What is static electricity?
Prediction: I think…because…
Vocabulary:
•    electricity-
•    attract-
•    repel-
•    electron-
Materials: balloon, string, tape
Procedures:
1.   Tie a piece of cereal to a string approximately 12
inches long.
2.   Tape the string to your desk.
3.   Rub the balloon against your clothing (to get a
negative charge) then hold the balloon next to the
cereal.
4.   Record your observations.
PROJECT 1 - Swinging cereal
What you need:
a hard rubber or plastic comb, or a balloon
thread, small pieces of dry cereal (O-shapes, or puffed rice of wheat)

What to do:
1. Tie a piece of the cereal to one end of a 12 inch piece of thread. Find a place to attach
the other end so that the cereal does not hang close to anything else. (You can tape
the thread to the edge of a table but check with your parents first.)
2. Wash the comb to remove any oils and dry it well.
3. Charge the comb by running it through long, dry hair several times, or vigorously rub
the comb on a wool sweater.
4. Slowly bring the comb near the cereal. It will swing to touch the comb. Hold it still until
the cereal jumps away by itself.
5. Now try to touch the comb to the cereal again. It will move away as the comb
approaches.
This project can also be done by substituting a balloon for the comb.

What Happened: Combing your hair moved electrons from your hair to the comb. The
comb had a negative static charge. The neutral cereal was attracted to it. When they
touched, electrons slowly moved from the comb to the cereal. Now both objects had
the same negative charge, and the cereal was repelled.
