Travel on an expedition to Antarctica to see the Ross Sea through the eyes of Adelie penguins, and then discover the geology of 300,000-year-old lava flows high on Mount Morning.

Using a common modeling compound, students form a "volcano" and examine its topography to predict which way lava will flow down its slopes.

Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model...
