In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream. Pairs of learners will combine ingredients in a plastic bag and then add varying amounts of rock salt to each bag. Learners will estimate how long it will take for their mixture to freeze and then measure the actual freezing times. At the end of the activity, learners can eat their ice cream! This resource explains how salt content lowers freezing points and includes tips about cold weather safety.
