What are Volcanoes made from and why do they erupt? How did the eruptions volcanoes make the Hawaiian Islands? In this location and experimental program, Bill Nye the Science Guy, examines the nature of Volcanoes and how their existence changes the environment they are located in. Bill examines the three different types of Volcanoes that exist and why they behave the way that they do. This program is an excellent entertaining resource to introduce primary students to the nature and behaviour of Volcanoes.
