Students observe how air quality changes over time, for a selected location, using data from the United States Environmental Protection Agency (EPA).

The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Before scientists may begin their work with these data, it is important that they understand what the data are.

Explore and connect to pedosphere protocols in GLOBE. Each protocol correlates to related datasets from the Earth System Data Explorer.

In this activity, we will introduce children to the colors of the sky. Children love to look at clouds. Here we will focus in on the sky in which clouds float. Children will learn why the sky has such a wide range of colors.

In this activity students will compare different methods for observing the Sun’s corona and make predictions about what they will observe during the April 8, 2024 total solar eclipse.

Explore the energy and matter cycles found within the Earth System.
