Students use Phytopia: Exploration of the Marine Ecosystem, a computer-based tool, to investigate various phytoplankton species and topics relating to phytoplankton biology.
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.
Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
