In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this activity, learners model erosion using a clear shoebox and sand or soil.
