The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. 

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).

Students collect and analyze temperature data to explore what governs how much energy is reflected. 

In this activity students will learn several ways to safely observe a solar eclipse.

Students will analyze a pie chart (circle graph) showing the distribution of different parts of the Earth system's absorption and reflection of energy. 

This hands-on activity is the construction of an extended coverage area of eclipse glasses to provide extra protection for safely viewing a solar eclipse. This makes it harder to look outside the lenses on the eclipse glasses.
