This week, we'll do a version of Saturday Morning with Mr. Science.
Each group will construct a working motor. You will be supplied with:
Preparation:
You may use anything else you wish, but you may need to bring any items not listed above. You may wish to explore the internet to get some ideas and/or plans. There are plans for a stripped down motor (from the Exploratorium). But you should search for other plans. I highly recommend the Google search engine at http://www.google.com/. The purpose of this lab is not to mindlessly follow one set of instructions, but rather to understand how a DC motor works and to design/construct a motor from this understanding.
Report/Grade
There will no formal lab writeup. Points will be awarded as follows:
| Description | Points Awarded |

| Visible evidence of any unassisted rotation | 7 - 8 pts |
| Something that looks unmistakably like a motor | 5 - 6 pts |
