Use the PhET simulation on DC circuits to 1. Make a light bulb light brightly using 4 batteries. 2. Add an on/off switch. 3. Make 3 light bulbs light brightly with all 3 the same brightness (same current, measures the same number of amps). 4. Have a switch that turns on/off 2 of the 3. 5. Have a switch that turns on/off all 3 lights. 6. Make a circuit with one main on/off switch that will turn on/off 3 bulbs, each with a different brightness. Use the non-contact ammeter to check for different currents. 7. Change the circuit so 1 switch will turn on/off all the lights and a second switch will change the lights from all being the same brightness to all being different brightnesses.
