Three of Earth's spheres are introduced to your earth scientists: lithosphere, hydrosphere, and atmosphere. Each are described with text, while a combination of photographs and computer images are displayed. One of the best ways to use...

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Dive into a lesson on the hydrosphere with this Powerpoint presentation. Building on prior knowledge of the water cycle, young scientists learn what happens to water after it falls as precipitation and explore the different factors...

In this atmosphere and hydrosphere worksheet, students work on assigned topic which are either categorized as human activity or natural activity which impact the atmosphere and the hydrosphere. Students work in groups and answer...

Students identify the major Earth systems, and describe at least ten major uses of water on planet earth. They research major sources of earth's water, and describe general aspects of the hydrosphere.

In this hydrosphere and atmosphere worksheet, students work in groups to present an assigned topic's effects on the atmosphere and the hydrosphere. They identify the topic as human activity or natural activity and it's impact.

Students describe the changes that have affected the Missouri River over the past 200 years by identifying transformations in this area's atmosphere, biosphere, hydrosphere, and lithosphere. They research online in groups assigned to...

In this Earth worksheet, students investigate the interactions between the four major parts of the earth-the atmosphere, the geosphere, the biosphere and the hydrosphere. Students discuss their findings as a class.

Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.

Is everything really connected? Take your class on a walk outside, where they will make observations and write them down on a worksheet. Once they are back in the classroom, learners will work to determine if and how things like birds,...

What effect does the hydrosphere have on the biosphere? What's going on below the surface of the ocean? As one goes deeper into the ocean, habitats, temperatures, pressure, and the types of living organisms change. This is the focus of a...

What are the other two spheres on Earth? The hydrosphere and atmosphere, of course! This is the focus of a video that explains what makes up the hydrosphere and atmosphere.

How do the geosphere and hydrosphere interact with one another to support life? This is the focus of a video that describes how the geosphere supports the hydrosphere and vice versa.

If less than 1% of Earth's freshwater is available for use, and people are constantly using it up, what's being done to save it? This is the focus of a video that discusses the human impact on the hydrosphere.

What is wind, and what does it have to do with the sun's energy? Wind is part of Earth's atmosphere; however, the geosphere and hydrosphere work together to create it. This is the focus of a video that explains how temperatures...

Students identify and define the main components of the hydrosphere and the ways in which they interact with one another. They explore how changes in Earth's surface materials affect components of the hydrosphere and evaluate the effect...

This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Having a clean, reliable source of drinking water is essential for any community, but in many cases this is easier said than done. Engage young environmentalists in exploring the five factors affecting vulnerability of a groundwater...

Investigate the different types of pollution that storm drain runoff carries into oceans, lakes, rivers, and streams with this class demonstration. Using an aquarium and an assortment of everyday items that contaminants like motor oil,...
