This activity has three story puzzles learners can solve to learn about life in the Arctic.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
