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:
