Learners explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

This site includes learning resources and activities for Earth Science Week 2016. The goal of the week is to "engage young people and others in exploring geoheritage throughout the Earth systems, including the geosphere, hydrosphere,...

Using a surficial features map, students see the connections between those features and other Earth systems. They will consider the interactions of the geosphere, hydrosphere, biosphere, and atmosphere.

In this activity, young scholars think about how various real-world careers relate to personal interests and Earth's systems- the geosphere, hydrosphere, atmosphere, and biosphere.

Using flubber and plastic wrap, students study the Earth's crust and mantle.

[Free Registration/Login may be required to access all resource tools.] Explains the cycle of carbon through the atmosphere, geosphere, and biosphere.

In this lesson, you will learn about how the Earth formed as well as the composition and structural layers of the Earth's interior.

Explains what the four spheres of the Earth are and describes how volcanic eruptions affect the different spheres. Also provides a list of events that are examples of interactions.

A slideshow and a short multiple-choice quiz on the rock surface of the Earth, its water, and the gas layers that surround it.

An Earth System Project shows the interaction between the Geosphere, Hydrosphere, Atmosphere, and Biosphere. This project provides a model of a pond ecosystem and can easily be woven into the hydrosphere unit.

Fifth graders develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
