Ice Cream

Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...

Students discuss the freezing point of water. They make their own ice cream using ice and salt mixtures.

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Here is a fun display that will help your physical science fanatics understand freezing points and crystal formation. Use rock salt, sparkling water, and ice to create a -10¡C bath. Place full bottles of soda into the slurry to supercool...

High schoolers define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

Students investigate melting and freezing behavior in substances. In this melting and freezing points lesson plan, students perform experiments to test the impact of various salts on the freezing point of water, they test the impact of...

Use boiling as an avenue for freezing. Young scholars watch as liquid nitrogen removes heat from the ingredients for ice cream. As this happens, the nitrogen boils and the ice cream freezes—all in the same container. A little science magic!

Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Students examine the freezing point depression of salt water by making ice cream. Lab activity begins with students layering a bowl with ice and salt around an empty cup before adding a mystery solution to the cup. They take the...
