This collection of learning activities allows students to explore phenology, phenological changes over time, and how these changes fit into the larger context of climate change. Students explore patterns of solar radiation and seasons as well as phenological cycles and ecological affects of these patterns.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.
