This lab uses an ice water bath, a hot plate, a thermometer, and a timekeeping device to enable students to create heating curves for water. It directly confronts the misconception that the system's temperature changes uniformly over time, and reinforces the difference between heat and temperature.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
