You have two assignments for this weekend.
1) Outline the 7.3 Physics Talk, which starts on page 736.
2) Read through the Investigate, which starts on page 734. We will do this in class on Monday, so make sure you have your battery and magnet with you. This will become your toy motor! Spend some more time thinking about your toy, now that you know what the battery will look like. If you want to modify it, come prepared to do so on Monday!
Here are some toy videos from previous years:

Quiz
Guys,
Click the link below, it will take you to your Quia homepage. There is a quiz posted up there, you have until class time tomorrow to complete it. You have 35 minutes and one attempt. It's all multiple choice, true/false, etc. You should use the same username and password as last time.
Good luck!

Outline the 'Electromagnets' Physics Talk, starting on page 727 of your textbook. Also, answer the 'Checking Up' questions.
Wednesday, November 14
On loose leaf, answer the following questions using your notes, textbook and the internet:
1) Do magnets have to touch each other in order to experience a magnetic force? Explain.
2) What is the difference between a permanent and a temporary magnet?
3) If I want to know the direction of a magnetic field around a permanent magnet, what should I do?
4) A strong magnet in a junkyard can lift a car; what does this tell you about the relative strength of the magnetic and gravitational forces on the car? What do you think creates this magnetic force?
Also, mess around with this (use all the tabs at the top - it's awesome!):

Answer the following questions in your notebook, under the heading "Chapter 7, Section 1. What Do You Think?" :
1) How many sides does a magnet have? What are these sides called?
2) A compass is really just a bar magnet. What does that mean about the Earth? How does the compass know to point North?
3) Do magnets need to be touching one another in order for you to feel a force between them? How do you know? Give examples.
