Students discuss their current understanding of what Earth systems are and how they work and consider how to identify the boundaries of a region for Earth system study.

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

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

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.

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.
