Physics 640: Physics Pedagogy
An On-line Course for Teachers of Physics

Week 5 Assignment: Demos

Assignment 1

Use the web and any other resources you have available to research demonstrations for projectile motion. Write a paragraph describing each of the following. Be sure to include a reference to any website you used and the PIRA DCS number for each demonstration. Link to DCS website. Upload this assignment to Open Portfolio as HW8. This assignment is due Monday, March 1, 2004, before 5 a.m.

1. Describe a demonstration you currently do for projectile motion and find a similar demonstration description at a college or university (do not use PIRA). Explain the similarities and differences in not less than 150 words.
2. Find three demonstrations that you could include in your lesson plans for under $5.00 each. Include the DCS, a web reference, and an explanation of the physics it demonstrates and a description in your own words. We expect this to be at least 500 words.
3. Find 3 different "monkey and hunter" demonstrations (1D60.30) and explain (in not less than 400 words total for all three):
   1. physics of the demonstration
   2. operation of each demonstration, i.e, What kind of launcher is used? How is the target released? What type of projectile is used? (ball, bullet, dart). Include a picture of each demonstration (copied from the web) if possible.

Assignment 2

Choose one of the demonstrations listed below and write up a complete lesson plan. You are on your honor to choose a demonstration that you do not currently have in your collection. These demonstrations will be available for all students taking this class now and in the future. No minimum length is given here, but this is a significant project. Upload this assignment to Open Portfolio as HW9. This assignment is due Monday, March 1, 2004, before 5 a.m.

For this assignment you need to include:

1. A description of the demonstration including the physics principles.
2. A presentation model for the demonstration: How would you present this to your class?
3. A picture of the demonstration you build.
4. Comments on how the demonstration could be improved.
