I hope you enjoyed making and eating your ice cream on Friday — I keep telling you science is fun!

• Have you figured out how heat was used? Remember that heat is the movement of thermal energy.
• Besides the changes in temperature what other observations did you make? Do you recall taking any notes that might relate to your observations?
• What was the purpose of the salt?
• Can you draw a picture showing the flow of thermal energy in your experiment?
• Were there any anomalies (unexpected results)? What might have caused them?
