In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

This series of videos highlights how NASA Climate Scientists use mathematics to solve everyday problems.  These educational videos to illustrate how math is used in satellite data analysis. 

This activity invites students to model and observe the effect of melting ice sheets (from land) on sea level and the difference between the effect of melting sea-ice to that of melting land ice on sea level.

In this activity students will examine NASA data to determine the differences between a solar and lunar eclipse.

In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).

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

In this lesson, students investigate and identify various phytoplankton using images that were previously taken with a compound microscope.  Credit:  This lesson is modified from a lesson of the same name created by The Center for Microbial Oceanography: Research and Education&nbsp
