Assignments:
Each student will be expected to purchase a reading booklet at the time of registration or at the first class. This booklet will contain material that should be read before the beginning of the second class. For our typical course, there are two full eight hour days of classes, although other schedules are possible. There must be several days between the two full day classes to allow a project to be completed.
Between the two classes, each student is required to research and build a project having to do with magnetism. The primary consideration is your understanding of the project, your ingenuity in producing it, and your description of how other teachers could also use it. A short typed description (perhaps only 2-3 pages) must be handed in giving resource material, instructions for building and using the item. A short discussion of how this project might be useful in the classroom would be appropriate. Also during the second class you will give a short (5-8 minutes) presentation to the class. A list of possible projects is given in this booklet, but each student is expected to do further research to improve on the ideas presented here. Do not just copy what is given here. Try to improve it. Bring in a D-cell battery for the last class.
Grading:
Because this is a graduate level class, only passing grades of A and B (with + and - possible) are given. A C grade is failing. It is also possible to audit the class, but ALL the work must be completed, including the project. Grades will be primarily assigned by the local adjunct professor and will depend on class attendance and participation as well as the presentation of the homework project. This presentation includes the oral one before the class as well as the document handed in describing the project. See the discussion above in Assignments. Anyone failing to complete the class will be given a grade of Incomplete, which if not completed will eventually result in a grade of F.
Reading Booklet:
A reading booklet will be prepared for class members that includes useful information on magnetism as well as possible homework projects and teacher applications. This booklet will be available at the first class. The booklet contains descriptions for the hands-on teacher activities we will perform during the class.
Instructor Contact:
Contact the local adjunct professor during the first class for her/his address and office hours. Professor Thornton may be contacted as described on the previous page. He will try to respond and will inform the adjunct professors of any decisions concerning the class. Thornton's address: Stephen T. Thornton, Department of Physics, University of Virginia, Charlottesville, Virginia. Email: stt@Virginia.edu

Only one person in a class can do a project unless otherwise indicated below. Reference material is contained in the Teacher Project folder that your Instructor has, but we do not have copyright permission to make additional copies. Remember that you are expected to use other reference material, not just the material contained here! The list of references used follows the Teacher Projects list.
1. Design a safe device that will demonstrate that two parallel wires with currents along the same direction will attract and with currents along opposite direction will repel. - Reference: Robert W. Wood, Physics for Kids, 49 Easy Experiments with Electricity and Magnetism (Tab, New York, 1990), page 101. Do not use a car battery as a source of current as I do in the demonstration on the 2nd Saturday
2. The Dancing Figure - Robert W. Wood, Physics for Kids, 49 Easy Experiments with Electricity and Magnetism (Tab, New York, 1990), page 106. Try to improve this project.
3. Making an Electromagnet Crane - Robert W. Wood, Physics for Kids, 49 Easy Experiments with Electricity and Magnetism (Tab, New York, 1990), page 109. This one is too simple. Add a mechanism to lower the electromagnet down into a bowl of paper clips. Include a switch to turn the electromagnet on and off. Try to add a mechanism to turn the crane left and right.
4. Making a Model Railroad Signal - Robert W. Wood, Physics for Kids, 49 Easy Experiments with Electricity and Magnetism (Tab, New York, 1990), page 119. This is too easy. Embellish it somewhat. For example, it needs a switch. See what else you can add to improve this project. See also Gabriel Reuben, Electricity Experiments for Children (Dover, New York, 1960), page 59.
5. Making a Motor - Robert W. Wood, Physics for Kids, 49 Easy Experiments with Electricity and Magnetism (Tab, New York, 1990), page 122. This is a different motor than the one we will build in class. It is worth doing.
6. Mapping the Earth's Magnetic Field Over Time - Janice VanCleave, Magnets (John Wiley & Sons, New York, 1993), page 56.
7. Make a Loudspeaker - David Macaulay, The Way Things Work (Houghton Mifflin, Boston, 1988), page 240. You will need other resources in order to build this.
8. Building a burglar alarm - David Macaulay, The Way Things Work (Houghton Mifflin, Boston, 1988), page 297. Include something that slides up and down or opens and closes.
9. Building an Electric Horn (Auto) - David Macaulay, The Way Things Work (Houghton Mifflin, Boston, 1988), page 299. This looks challenging.
10. Make a Report On a Maglev Train - David Macaulay, The Way Things Work (Houghton Mifflin, Boston, 1988), page 302. This must be an extensive report with diagrams of the principle of operation. This will have to be longer than 2-3 pages. Posters with the diagrams would be appropriate. Do extensive library research.
11. Faraday's Electric Generator - George deLucenay Leon, The Story of Electricity (Dover, New York, 1983), page 38. You will need to figure out how to hold everything down and secure it, particularly the crank. This is a neat project.
12. Making a Microphone - Gabriel Reuben, Electricity Experiments for Children (Dover, New York, 1960), page 53.
13. Making a Generator - Gabriel Reuben, Electricity Experiments for Children (Dover, New York, 1960), page 54.
14. Making an Electric Motor - Gabriel Reuben, Electricity Experiments for Children (Dover, New York, 1960), page 57. This is a different electric motor than the one we will build in class, and this one is worth doing.
15. Making a Magnetic Boat - Judith Hann, How Science Works (Reader's Digest, Pleasantville, NY, 1991), page 163.
16. Making a telephone - Judith Hann, How Science Works (Reader's Digest, Pleasantville, NY, 1991), page 168.
17. Building an Electric Meter - George Barr, Science Projects for Young People, (Dover, New York, 1964), pages 25-30.
18. Making a burglar-proof bag - George Barr, Science Projects for Young People, (Dover, New York, 1964), pages 30-33.
19. Magic dancer (hide two or more magnets, one in leg) - Tik L. Liem, Invitations to Science Inquiry, 2nd ed., (Science Inquiry Enterprises, 14358 Village View Lane, Chino Hills, CA 91709, 1987), page 223. Do with one magnet below and then with three or more magnets below to show chaotic behavior.
20. Magnetic Fields Around Current Carrying Wire - The Exploratorium Science Snackbook (1991), pages 22-1.
21. Floating Pencil - Paul Doherty and John Cassidy, The Klutz Book of Magnetic Magic (Klutz, Palo Alto, CA, 1994), p. 45. You will probably have to obtain the book to do this experiment, because the magnets to do the project come with the book.
22. Mysterious Coin - Paul Doherty and John Cassidy, The Klutz Book of Magnetic Magic (Klutz, Palo Alto, CA, 1994), page 51. This one looks tough.
23. Making a Door Bell - Tik L. Liem, Invitations to Science Inquiry, 2nd ed., (Science Inquiry Enterprises, 14358 Village View Lane, Chino Hills, CA 91709, 1987), page 268. David Macaulay, The Way Things Work (Houghton Mifflin, Boston, 1988), page 298. Judith Hann, How Science Works (Reader's Digest, Pleasantville, NY, 1991), page 165. More than one person can do this project.
