Physics Demo Manual

Demonstrations are cataloged according to PIRA Bibliography


Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Various items may be used to demonstrate a number of different principles involving heat transfer and conduction. The bunsen burner or torch may be used. There are pieces of insulation or gloves which can be used to protect the hand from a hot flame. There are solid metal bars and hollow metal tubes which can be heated. Very thin walled stainless steel tubing can be used to show that not all metal structures are excellent heat conductors. One end may be heated white hot while the other end is cool enough to hold in the hand.
