Master List of Available Demos and Order Page

The demonstrations in this index include nearly all of the PIRA 200 and then some local favorites.

The PIRA 200 represent the most commonly physics demonstrations
used by major universities in the United States. Other demos outside of the
Physics Instruction Resource Association's Top 200 are so noted.

Demo Requests, are due before we close on the weekday afternoon, prior to your class date.

Business hours are Monday thru Friday, 8:00 AM - 4:00 PM, excepting holidays.

- Same day demo requests are problematic for all involved. -

Demonstration Ordering Procedure:

1) Click on the boxes next to the appropriate demonstrations to select a demo for your request.

    An [x] will appear in the box. (Example: _[x]_ 1A60.10 Scaling: Powers of Ten)

2) For a demonstration description, click on the blue PIRA demo number.
    The blue PIRA number links to a photo and a short description of each demonstration.

3) After selecting your demonstrations, click on the Go to Form link or scroll to end of this page.

    Go to Form is a link that automatically scrolls down to the bottom/end of this web page.

4) Enter and select the required information into the provided form located at bottom of this page.

    Special Note: Without the proper faculty member's name, password, day of demos, time and room entered into the form fields, our office will not be able to process your demo request.

5) After checking to see if the above fields are correctly filled in, click on the SUBMIT icon.
    This will process the demo request to our Calendar Page.

6) Suggestion: As a final step, click on the word verify on the next screen to verify the requests were processed correctly.
