Electical and Magnetic Forces and Fields

ASSIGNMENT 1:

1. Click the "Johntravoltage" Link above and play around with the simulation for a minute.

2. Write a summary or tell me what is happening that causes the electric shock to occur when he touches the door.

ASSIGNMENT 2:

1. Watch the video above on Electric Charge and Coulomb's Law.

2. As you watch, create a bubble map for Electric Charge and Coulomb's Law. Be sure to include any relevant formulas, and indicate what each variable in the formula means.

ASSIGNMENT 3:

1. Select the link on the right above with static electricity and the balloon.

2. Play around and observe what is happening to electrons.

3. Then, find a way to demonstrate static electricity. Either create a video and email or draw and describe how you were able to demonstrate static electricity.

ASSIGNMENT 4:

1. Use one (or both) of the videos to show you how to calculate forces between charged particles.

2. Then, open Coulomb's Law practice above and complete your work on your own paper. Take a picture and email it to me, including YOUR WORK!!!!!!!!!

ASSIGNMENT 5:

1. Watch one of the videos above on building an electroscope.

2. Then, see if you have materials available to make your own.

3. When you've made your electroscope, demonstrate how it works in a video to me.

4. When you've successfully demonstrated how it works, write 3-5 complete sentences summarizing what you've learned.

5. If you can't actually make your own, describe how you COULD make one and how it would work.

ASSIGNMENT: SKIP

1. Watch the video above to introduce the idea of magnetic fields. We will begin the unit by showing magnetic fields using a magnet and iron filings.

2. See me for a copy of the lab and materials.

ASSIGNMENT 6:

1. Watch the video above on magnetism.

2. As you watch, create a bubble map on Magnetism. Be sure to include any relevant equations and what each variable in the equation represents.

ASSIGNMENT 7:

1. Watch the video on bar magnets and compasses.

2. Write a 3-5 sentence summary of factors that effect the direction of the arrow on a compass. In your summary, research what might cause a compass to give a bad reading. Please use complete sentences!

ASSIGNMENT 8:

1. Open the link above for a virtual lab about how magnetism works in a transformer.

2. Open the data table icon and copy the data table you will fill in while completing the lab.

3. Then, use the instructions on the left hand side of the screen to complete the virtual lab and fill in your data table.

4. Finally, click on the journal icon and answer the journal questions using complete sentences.

ASSIGNMENT 9:

1. Open the link above for a virtual lab about how magnetism works in a generator.

2. Open the data table icon and copy the data table you will fill in while completing the lab.

3. Then, use the instructions on the left hand side of the screen to complete the virtual lab and fill in your data table.

4. Finally, click on the journal icon and answer the journal questions using complete sentences.

ASSIGNMENT 10:

1. Research the historical development of the concept of electromagnetism. Organize your findings chronologically or by scientists’ contributions to our current knowledge of the subject.

OR

2. Build a simple motor to demonstrate your knowledge of electromagnetism.

OR

3. Give an oral or written report analyzing the motion of the motor. You may choose your format (how you will present it). The videos above may serve as inspiration for your motor set-up.

Include the following in the report:

• Polarity of charge
• Magnet strength
• Number of coils
• Demonstration of right hand rule as applied to the motor
• Related historical information from your research
