For this activity, students were assigned ice crystal phenomena and instructed to build paper models of the crystal that comprise of 22° degree halos, parhelia, tangent arcs, and more. In addition to this, students discussed weather associated with ice crystal phenomena to gain a better understanding of the relationship between weather conditions and phenomena that are made visible because of them.

Working in groups of three, students were given a possible future configuration of the Earth's continents and asked to use the knowledge they have obtained throughout the class to describe the climate of that future Earth. Students drew out their configurations and were asked to answer questions about global wind patterns and ocean circulation patterns, hurricane seasons, tornado alleys, polar ice caps, and other climate factors.
