Volcanoes
HASS Year 8: ACHGK050 - the geoprahical processes that produce landforms, including a case study of one type of landform (in this case, volcanoes).

Science of the Earth Unit 19: The Day the Earth Erupted - Volcanoes
Students look at two contrasting volcanic eruptions and the plate tectonic explanation for the differences. Students develop an understanding of how vocanoes 'work' and the different types of eruption and why they are different.
They also relate volcanity to plate tectonic theory. A variety of activities are provided, split into nine sections with teachers' notes and lesson planning suggestions with possible homework activities.
Yellowstone: Supervolcano
This film, from Twig World, looks at the super volcano which lies beneath Yellowstone National Park. The film explores why we can't we see it and whether it ever erupt.
The key points made in the film include:
•Yellowstone National Park sits on a supervolcano.
•Yellowstone boasts hydrothermal features fuelled by the supervolcano.
•There is evidence of a massive depression called a caldera, which suggests that the last eruption of the volcano happened 640,000 years ago.
•When Yellowstone's supervolcano next erupts it will produce an explosion with the power of 1000 atomic bombs.
Journey to Etna
These videos shows Clive Oppenheimer, a volcanologist working on the latest techniques to monitor and predict volcanic eruptions. He demonstrates his work at Mount Etna, an active volcano in Sicily. Volcanic eruptions pose a real threat to communities living nearby. At their most violent, volcanoes have wiped out whole cities.
Clive meets with his research students who monitor the volcanoes. He takes a trip to Mount Etna to view old lava flows and collect fresh lava samples.

The Position of Volcanoes on the Earth and Mars
Take out the bits about volcanoes on Mars and you've got yourself a lovely lesson on volcanoes, mainly location and why they're there (tectonic plates).
Volcanoes on Earth and Mars
Students will use topography data to plot the shapes of various volcanoes on Mars, and compare these with the shapes and dimensions of volcanoes on the Earth. They will then investigate reasons why (such as a weaker gravitational field) volcanoes on Mars are so much higher and broader than those on the Earth.
Maybe take the Mars bits out? Or maybe leave it in for student interest?
Fire and ice
This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.
Earth Science - Volcanoes
The films in this collection look at how scientists study volcanos. The films contain footage of volcanoes erupting and cover areas such as the formation of islands, types of eruption, the structure of volcanos and whether we can predict eruptions.
