End-of-Course Extra Credit

Now that we are at the end of the course, we just finished our unit on electricity. If, for some reason, you are not satisfied with your class grade, here is an extra credit project that can add points to you final class grade. Build a lemon battery. It will take a little time and money (you have to buy the lemons etc.), but it will be worth it. Follow the instructions in the video below.
Build your battery, show that it works, add 5 points to your final class grade.

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.

Unit 10 - Work, Power, and Simple Machines

In this unit we are going to continue our study of the motion of objects by learning how machines help us move objects. In the process we will learn what is meant by "work" and how machines make doing work easier.

Most of our instruction will be video lessons and worksheets, supplemented by direct instruction and class discussion.

SPS8e: Calculate amounts of work and mechanical advantage using simple machines.

Specific assignments:

Assignment 1: (Class Activity) Watch two short videos on "Simple Machines". Take notes, and answer the questions on the Simple Machines worksheet which includes copies of the questions to the Video Quiz given at the end of each of the videos. (Click here to see worksheet)





Assignment 2: Mechanical Advantage -- mini lecture. Take notes and then complete the appropriate problems on the Work, Power, and Simple Machines worksheet. (Click here to see worksheet)

Watch this video on how to see how to calculate the Mechanical Advantage of a pulley.



Click here to view power point presentation that summarizes how to calculate the Mechanical Advantage (MA) of simple machines.

Assignment 3: Work, Power, and Efficiency - mini lecture. Take notes and complete appropriate problems in the Work, Power, and Simple Machines worksheet.

Here is a good description of what we mean by "WORK." Watch this video. Write down the formula for work.
