Basic Circuits with PhET

10

In the PhET simulation, click play, click on "Intro" and then build a complete circuit with the following criteria: wire, bulb, battery, switch. Close the circuit. The current should be flowing. Take a screenshot or picture and post it here.

Add a second bulb to your circuit. What does this do to the brightness of the bulbs?

5

Add a second battery to your circuit. What does this do to the brightness of the bulbs?

5

Explain your answers to 2 and 3. What is happening in terms of current when you add a bulb or add a battery?

5

Turn one of the batteries around backwards. What does this do to the current in the circuit?

5

Turn your battery back around so that everything functions once again. Now cut open your circuit somewhere so you can test some objects for conductivity. Find the coin and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)

5

Cut the circuit and remove the coin. Find the hand and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)

5

Cut the circuit and remove the hand. Find the pencil and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)

5

Cut the circuit and remove the pencil. Find the paper clip and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)

5

Cut the circuit and remove the paper clip. Find the eraser and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)

5

Cut the circuit and remove the eraser. Find the dog and insert it into the circuit. Based on the evidence, is it a conductor? (yes or no)
