Check out this the Arctic and Earth SIGNs video to explore how climate models are used in climate change research.
In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.
