Our Earth is a dynamic system with diverse subsystems that interact in complex ways. Questions that scientists have about the Earth as a System may include the following. As you learn more about the Earth System, reflect on these questions. 

In this activity students will calculate the ratio of the size of the sun to the moon and the distance of the sun and moon from Earth to determine the type of solar eclipse possible.

In this interactive, students will learn the basics of space weather by engaging in a short interactive which introduces key terms: space weather, sunspot, solar flare, coronal mass ejection, and solar wind. Students will be able to identify the causes and hazards of space weather.

These six graphs show Ocean Chlorophyll Concentrations from 1998 - 2018 in a variety of locations: East Bering Sea, Gulf of Alaska, California Coast, Southeastern US/Gulf of Mexico, Northeastern US and the Scotian Shelf, and the Hawaiian Islands.

This lesson uses the National Park Service Story Map which displays national parks around the contiguous United States and their standard exceedance ozone concentrations from 2016-2021. Students will explore ozone levels and answer questions.

Several heat domes have occurred over the last few summers and around the world. This lesson provides one example from 2021 in Portland, Oregon, with temperature and ozone data.

The Earth can be considered a system of interrelated parts. Learn about Earth Systems Science and the spheres that make up the Earth System. Find out why NASA studies the Earth system.

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

Students are divided into three different groups and are assigned a category of drivers of change in regional trends of freshwater storage (Climate Change, Human Activity, and Natural Variability).
