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

Students observe the surface temperatures of a variety of surface types found in a suburban environment.

The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.This animation shows the long-term average sea surface temperature, with red and yellow depicting warmer waters and blue depicting colder waters.  

Students observe images, individually, looking for changes in surface air temperatures (using data displayed, unit of measure, range of values, etc.) and patterns noticeable within the maps.

The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using these two 2017 maps created using NASA satellite data, have students review the seasonal differences of snow and ice extent.
