March 5 Making Ice Cream Investigating the transfer of heat energy Essential Question: When making ice cream which way does the heat flow? Objective: They should understand how thermal energy is the movement of the tiny particles that make up a substance and should be able to apply this to phase changes. The children all ready know the phases solid, liquid, gas, and are aware that as you go from solid to gas the thermal energy of the substance increases. The students are also aware that heat always travels from something that is hot (more thermal energy) to something that is colder (less thermal energy). This should all be quickly reviewed during the activity. Materials: For each bag of ice cream you make you will need the following: • 1/2 cup milk • 1/2 cup whipping cream (heavy cream) • 1/4 cup sugar • 1/4 teaspoon vanilla or vanilla flavoring • 1/2 to 3/4 cup of rock salt (Box will say ice cream salt) • 2 cups ice • 1-quart Ziploc bag • 1-gallon Ziploc bag • thermometer
