Week 8 - Electricity and Magnetism

Earlier we studied the structure of the atom and discovered that all atoms are made of protons, neutrons, and electrons. In this unit we will study an interesting property of electrons -- they can flow from one atom to another. We call this flow electricity. We will explore the of electricity and its inseparable connection with another property of matter - magnetism.

Instruction will be a mix of mini-lectures with "show and tells," and video lessons coupled with class discussion and two lab activities.

Specific lessons:

Assignment 1: To introduce the topic of electricity, we will view the short video below entitled "Electricity." Use the information from the video to help define any applicable vocabulary terms you see listed in the Electricity and Magnetism - vocabulary worksheet. (Click here to see worksheet)



Assignment 2: Ohm's Law - mini lecture. Take notes. Continue to complete appropriate definitions to your vocabulary worksheet. Be prepared to discuss what you have learned.

If you miss the mini-lecture, watch the following video version of the lecture entitled "Ohm's Law."



Assignment 3: Series vs. Parallel Circuits -- mini lecture. Take notes and draw any diagrams. Continue to add appropriate definitions to your vocabulary worksheet.

Review what you learned by watching the video version of the lecture on series and parallel circuits.



Lab Activity: Circuits. Materials to build circuits will be provided.

Assignment 4: Direct Current vs. Alternating Current - mini lecture. Take notes. Be prepared to discuss what you have learned. Continue to add the appropriate definitions to your vocabulary worksheet.

Lab Activity: Build a Battery. Battery kits and instructions will be provided.

Quiz: This will be an "open book" quiz. You may use any notes you have taken as well as anything written on your Electricity and Magnetism - vocabulary worksheet. Click here to view a copy of the quiz.

Assignment 5: Magnetism -- min lecture. Take notes. Be prepared to discuss what you have learned.

Watch the following short video on electro-magnetism.



Assignment 6: Electromagnetic Induction - mini lecture. Take notes.

Watch the following video on electromagnetic induction.



Assignment 7: Motors and Generators -- mini lecture. Take notes, then watch video (below) by the same title.

Review by watching the following video on motors and generators.



Quiz: Unit quiz on everything you learned about electricity and magnetism. Review by studying you vocabulary and watching the short video that accompanies each lesson. Quiz will cover static electricity vs. current, direct current vs. alternating current, Ohm's Law including problems, Magnets, Electromagnetic Induction and how electromagnetic induction is used to create motors and generators.
