Name ________________________________ Period _______ Date______________Electricity and Magnetism Stations Lab Directions

Answer all questions in complete sentences.Station 1

Directions: Create a complete circuit using the materials at this station.

1. Explain why it is necessary to have a closed circuit.

2. From where did the energy come to power the load?

3. Draw a diagram of your complete circuit. Include all components of the circuit with colors and labels.

Station 2

Directions: Using a balloon and the fabric provided, attempt to charge the balloon by rubbing the fabric all over the surface. Now, perform two tests.

1. Can you pick up confetti with the charged balloon? Why or why not?

2. Can you make the balloon stick to the wall? Why or why not?

3. What type of charging does this station represent?

Station 3

Directions: Use only ONE “9 volt” battery to create an electromagnet with the ultimate goal of making the compass needle move. Insert the four different rods (aluminum, steel, copper, glass) as cores in the two solenoids.

1. Which core made the strongest electromagnet?

2. Which solenoid made the strongest electromagnet?

3. Draw a labeled diagram of your strongest electromagnet in the space below.

4. Explain how attaching a voltage source to a coil of wire creates an electromagnet.

5. What specific changes could you make to increase the strength of your electromagnet?

Station 4

Directions: Magnetize a masonry nail using a horseshoe magnet. Try to attach as many paper clips to your nail magnet as possible.

1. How did you magnetize the masonry nail? Give a detailed description so that someone could repeat what you did.

2. How many paper clips did you attach to your nail magnet?

Station 5

Directions: Go to the video https://www.youtube.com/watch?v=AhLbYaIoxsE and watch the demonstration.

1. During the VDG generator demonstration, what type of charging have you witnessed? Explain.

Station 6

Directions: Observe the compasses around the bar magnet.

1. Explain why the compasses are each facing a different direction.

2. Why is the larger compass facing North, while the other compasses may not?

Station 7

Directions: Explore the various magnets. Nothing should touch the iron filings directly.

1. When you place a magnet under the iron filings container, what happens?

Station 8

Directions: Create a circuit using the hand crank and the red bulb. If you do this correctly, a small light bulb will illuminate.

1. Explain the energy transformations occurring in these devices.
