Answering the following questions will help you to focus on the outcomes of these experiments: Construct a graph of temperature versus time. Put temperature on the y-axis and time on the x-axis.
Graph all three sets of data on the same graph. Use a different colored pencil for each test material. Provide a key on the graph relating the pencil color to the test material.
Calculate the change in temperature from start to finish for the air and each of the samples and record on your data sheet.
Which water sample lost the least amount of heat energy over the 6-minute time interval?
Was the rate of heat loss constant during each experiment? How can you tell?
Which material was the best insulator? Which material was the least effective insulator?

Submit your data sheet, graph, and answers to all of the questions in the essay box below.

In this experiment, use the steps of the scientific method to explore using a “coffee cup” calorimeter to measure the rate of heat loss for several substances and determining which of the substances is the best insulator. You will be testing the insulating capabilities of three types of fabric and the control will be air. The three types of fabric are:

Test Sample 1: 52% cotton/48% poly fabric
Test Sample 2: 100% acrylic fabric
Test Sample 3: 80% cotton/20% poly fabric
For the control, and each test sample, you will be measuring the amount of heat lost by the water in the calorimeter over 6 minutes, taking the temperature every 30 seconds. Be sure to record your data on your data sheet . View the animation to complete this experiment.
