Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes. 

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, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

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