1. Build a circuit (in Series) to turn on three light bulbs. 2. Connect three light bulbs in a series circuit so that if one bulb is disconnected both bulbs go out.
3. Build a circuit (in Parallel) to turn on three light bulbs. 4. Connect three light bulbs in a Parallel circuit so that if one bulb is disconnected the other bulb will remain lit.

Zoom Replacement Grade- 1. Select systems. 2. Create a system that involves all 5 forms of energy.
1. Rub a balloon on a sweater.
2. Predict what happens when a charged balloon is moved closer to the neutral wall.
3. After rubbing the balloon on the sweater, how does the charge on the balloon compare to the charge on the sweater? What happens to the positive charges? What happens to the negative charges?
4. Remove the wall, and use two balloons to explore attraction and repulsion. How do the +/- symbols help you decide whether something attracts or repels?
5. Explain how a balloon can be strongly or weakly attracted to the sweater.

6. Compare John Travoltage to Balloons and Static Electricity. How does bringing a charged a balloon close to the wall compare to rubbing John’s foot on the carpet and bringing his finger close to the door knob? How do these situations differ?
1. Predict what will happen to John if he drags his foot on the carpet.
2. What happens when his finger gets close to the door knob?
3. Observe discharges with John’s arm in several different positions. Explain how arm location and charge accumulation affect discharge.
4. How do charging and discharging compare? How charging can go unnoticed, but discharging is often accompanied by a shock? Explain.
5. Try building up charges while John’s finger is touching the doorknob. Explain your observations. •

2. Predict what happens to the brightness of the bulb when the number of turns in the coil is reduced by half, but the speed of the magnet remains the same.
3. How does the speed of the magnet affect the brightness of the bulb?
