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

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

Through guided inquiry, students will identify interactions of the four major scientific spheres on Earth: biosphere, atmosphere, hydrosphere and geosphere. They will then identify how these systems are represented and interact in their classroom aquarium.

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

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

This mini lesson focuses on the 2015-2016 El Niño event and how its weather conditions triggered regional disease outbreaks throughout the world. Students will review a NASA article and watch the associated video to use as a tool to compare with maps related to 2015-2016 rainfall and elevated disease risk, and answer the questions.

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