Heat and Energy Transfer Lab
Materials needed:
Part 1: bowls (not included in the lab kit; use cooking pots or plastic containers- something large enough to fit your hand) ice (not included in the lab kit) thermometers Part 2 test tubes – use three similar glasses or cups water various household materials for insulation stove or microwave to heat up water

Part 1: Heat transfer and human sensation

1. Pour warm water in the bowl on the left, cold water in the bowl on the right, and room temperature water in the bowl in the middle. Room temperature water should be around 20-22°C.

2. Put your left hand in the warm water bowl and your right hand in the cold water bowl. Leave them in those bowls for one minute. How do

Be careful! The water will be extremely hot!

6. Once your test tubes and your data table are prepared, CAREFULLY pour HOT water into the first test tube. You will need to fill up about ¼ of the test tube. Make sure the amount of hot water is the same in each test tube.

7. Measure the temperature of the water in each test tube every 30 seconds for 5 minutes. Record your data in your data table.

8. Repeat the same measurements with the second test tube. Just as before, start out with boiling water.

7. Describe some things that might have affected your results below.
Some things that could have affected my readings could have been that I have the air conditioning on in my house and the over head fan was on above my experiment._
Data Table 1
(place your table here)

8. What conclusions can you make from the data you collected? Which material seems to be a better insulator, and why?
The insulated glasses held heat better than the one that didn’t. The one that held the heat better would be the tin foil because of the heat being trapped inside______

9. Imagine that you visited your grandmother and she gave you a casserole covered with aluminum foil. Based on your experiment, is aluminum a good insulator? How does it prevent the heat from escaping?
In my case it is a very good insulator and helps with trapping the heat in.

10. Building on the previous question, try to explain
