Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world.
Students will describe the changes in a newly-formed volcanic island over the first three years of its life.

Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make false color images which allow us to see patterns more easily. Students will make a false-color image using a set of numbers.
This lesson walks students through the use of Landsat false-color imagery and identification of different land cover features using these as models.
