Friday, November 30

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:

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!

Guys,
Make sure you check back here tomorrow for information about work due for class on Friday (including your online quiz). More details to come...

Monday, November 26

Complete the 'Inquiring Further' questions 1-3 on pages 732 and 733 of your textbook.

Tuesday, November 20

Finish the Physics to Go questions on page 732, numbers #1-6.

Happy Thanksgiving!

Monday, November 19

Finish your investigate questions. The link below is the simulator we used in class, feel free to use it to help you answer the questions.

Also, read the chapter challenge, which starts on page 710. Then, research toys that use electromagnets/motors. Make a list of at least 5 of these toys in your notebook.

Thursday, November 15

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 7.1 Physics to Go questions #1-5

Friday, November 9

Complete all of the following for Monday:

1) If you did not receive a √on your 7.1 outline, you should add to it/amend it appropriately (as per our discussion in class today).

2) Finish the Investigate B, if you have not already.

3) Answer the 'Essential Questions' on page 723 of your textbook.

Have a nice weekend!

Wednesday, November 8

Outline the 7.1 Physics Talk, which starts on page 717 of your textbook

Tuesday, November 6

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.
