Ice Cream

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

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!

Here's a sweet lesson for your ice cream lovers! Scholars explore the effect temperature and emulsifiers have on the creation of ice crystals. They see that making slight adjustments changes the consistency of ice cream by...

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

Students 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.

Students investigate the effects of temperature change on phase changes. They explore the effects of changes in freezing point and incorporate the law of conservation of energy. They utilize these concepts to make ice cream.

High schoolers explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.

How does the amount of water required to grow alfalfa impact ice cream prices? The PBS food science video, part of a larger playlist, explains how farmers use water to grow the alfalfa that is fed to dairy cows. the video introduces the...

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...

Hot off the press! The Higgs boson may be proven to exist! In an ice cream "bar," two shady cartoon characters discuss the news. Since all particles are excitation of fields, the presence of this fundamental particle suggests that the...
