Abstract
In this article I introduce three lab activities, appropriate for a high school physics course, that are related to temperature and thermodynamics. The first of these is a graphing lab where a dual Fahrenheit-Celsius thermometer is used to create a best-fit trend line that serves to introduce this graphing skill. The second is an experiment to find the melting point of coconut oil, which is a convenient and widely available substance, with a phase change in a safe temperature range. The third is a safer alternative or follow-up to the classic “Burn a Peanut” lab, where I have students investigate how many calories are in a “heat pack” hand warmer. The labs are designed to be affordable, easy to set up, and work well as inquiry investigations.
