Objective:

Procedure:

Set up a thermometer ahead of time in a beaker of room temperature water. Also, have hot water on hand ready to go at the beginning of class.
Explain how to read a thermometer.
After splitting students up into groups of 2 or 3, have them write the hypothesis, variable, and controls for the lab looking at how fast water cools. Then have them perform the lab.
When finished, help students calculate the rate of temperature change between the 2 samples.
