This series of two lessons uses cutting-edge scientific research on the effects of climate change on communities in the intertidal. Through a combination of a dynamic presentation and several videos, students are introduced to the effects of climate change on the ocean (ocean acidification and temperature increase) and what is known about how ocean organisms are affected. Then students read and interpret graphs and construct a scientific explanation based on data from this research.

This activity has students examine the misconception that there is no scientific consensus on climate change. Students explore temperature data and report their conclusions to the class. Then students examine techniques of science denial and examine a claim about scientific consensus.
