Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.
Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018.
Students watch a NOVA PBS video about the different effects of clouds on climate and Earth's energy budget. Then they answer questions and brainstorm to complete a flow chart of events that might occur if the percentage of absorbing clouds increases.
Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.
