Compare pictures of different volcanoes. Then visit NASA's Space Place to learn about volcanoes and answer questions about volcanic eruptions.

Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

Watch NASA videos about aerosols and volcanic ash.

Examine the images to see the projected differences in land use between 1900 and 2100. 

The fires in Greece during the summer of 2007 devastated large tracks of forest and ground cover in this Mediterranean region. Students analyze these data to determine the scale, area, and percentage of the forest impacted by of these fires.

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Compare images from two volcanic eruptions in the Kuril Islands which occurred ten years apart and complete a graphic organizer for impacts on different Earth spheres. 

Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.

Students learn how to estimate the "energy efficiency" of photosynthesis, or the amount of energy that plants absorb for any given location on Earth. This is the ratio of the amount of energy stored to the amount of light energy absorbed and is used to evaluate and model photosynthesis efficiency.
