Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.

An urban heat island is a phenomenon that is best described when a city experiences much warmer temperatures than in nearby rural areas. The sun’s heat and light reach the city and the country in the same way. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.
In this activity, students make a claim about the cause of ocean currents and then develop a model to explain the role of temperature and density in deep ocean currents. This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.
Watch NASA videos about aerosols and volcanic ash.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model.
