oneone GTE-5B Objective: To conduct static electricity experiments in order to determine how charged objects affect each other. Energy Note: How do charged objects affect one another? Drill: 1. Take out your Station Sheet and your Station Chart 2. Did you have any problems with the homework? 3. In your log book write the 3 methods of transferring charges. Explain.

oneone GTE-5B STATIC ELECTRICITY AND THE ATOM There are three methods by which charges are transferred, friction, conduction, and induction. 1.Friction is the transfer of electrons from one object to another by rubbing. 2.Conduction is the transfer of electrons from a charged object to another by direct contact. 3.Induction is the movement of electrons to one part of an object by the electric field of another object.

oneone GTE-5B You will be performing experiments at a variety of stations. You may not get to every station. This is OK. For each station you are to: 1.Tell what you did. 2.Record your observations. 3.Try to explain what you observed. (Think about the charges of each object before they are brought together.)

oneone GTE-5B ***After each experiment discharge all materials. Before you begin each experiment you may wish to see how the uncharged materials react when placed near each other.

oneone GTE-5B Balloon Head (DEMO) Object 1: Balloon (charged) Object 2: Hair (opposite charge) Charging: Rub balloon on hair Action: Release the balloon Prediction: Result: The balloon sticks to the hair. Oppositely charged objects attract.
