Students observe an in-classroom visual representation of a volcanic eruption. The water-powered volcano demonstration is made in advance, using sand, hoses and a waterballoon, representing the main components of all volcanoes. During the activity, students observe, measure and sketch the volcano, seeing how its behavior provides engineers with indicators used to predict an eruption.

Students learn about the causes, composition and types of volcanoes. They begin with an overview of the Earth's interior and how volcanoes form. Once students know about how a volcano functions, they learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an eruption, seeing how a volcano gets its shape and provides us with clues to predict a blast.
