Guidelines for the term project can be found here in html and pdf.
Some possible term project ideas can be found here.
The following are some example term projects from prior semesters. Use these to get a feel of what is required of your term project. Remember that these are good but by no means perfect examples.
 | Supercooling.pdf This is an investigation of "super cooling." When thermal energy is extracted from water at 0 degrees C, the temperature doesn't usually change. The lost energy simply causes some of the water to freeze. If the energy is extracted very slowly and the whole system is carefully kept at the same temperature, there is no asymmetry to "tell the water" which molecules should freeze. So, instead of freezing the temperature drops below the freezing point. When the "super cooled" water is disturbed, freezing rapidly occurs.

| Compression Ratios in the Otto
Cycle Follow the link to see a presentation done by one of my students in class (this is not the write-up that he handed in). His project explored how engine efficiency depends on the compression ratio of the engine, as predicted by our analysis of internal combustion engines in class. He did this by machining a new head for his go-kart motor which would increase the compression ratio of the engine. In the process he learned a lot of physics and engineering, and also learned (and taught me) a lot about car engines. | ||
| guitar.pdf This is a study of the vibrations of a guitar string using a model which includes a non-linear dispersion. The results are compared to a real string using parameters extracted using Fourier analysis. | ||
| thermalexpansion.pdf This is a study of the thermal expansion of water. Using a large reservoir and a narrow straw, they were able to "amplify" the effect such that very precise measurements could be made. They were able to verify that water has a density maximum a few degrees above freezing. | ||
| oscillator.pdf This is a different approach to the term project in which an aspect of the course was studied in more depth theoretically. They do calculations using the program "Maple" to investigate the effects of damping on a harmonic oscillator. Note that the entire paper is a Maple workbook! | ||
| entropy.pdf This student chose to write a java applet as part of his term project. The applet, which demonstrates how entropy increases in a gas, can be seen by following the link below: entropy applet |
