Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
In this experiment, students make a claim about the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.
Students collect and analyze temperature data to explore what governs how much energy is reflected.
This lesson walks students through the use of Landsat false-color imagery and identification of different land cover features using these as models.
In this NASA-JPL lesson, students create a model of a volcano, produce and record lava flows, and interpret geologic history through volcano formation and excavation.
