Hold the Heat: Global Warming and Calorimetry

In this Activity, students perform quantitative calorimetric measurements on samples of ice/water heated by incandescent light bulbs and/or convection with room-temperature surroundings. They measure and graph temperature as a function of time.

A Candle in the Wind

In this Activity, students investigate physical changes that occur in a candle to learn how a candle functions and how you can blow it out. This Activity is based on a series of lectures presented by Michael Faraday in the 1850s.

Rubber Bands, Free Energy, and Le Chatelier's Principle

In this Activity, students compare the temperature change of a rubber band that is quickly stretched compared to one that is quickly relaxed. They predict what effect the stress of heating will have on a stretched rubber strip and test their prediction.
