Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Less than one percent of the water on Earth is usable in people's homes. As pupils consider this fact, they reflect on their own water usage before designing a survey to collect information on water usage by others. They then analyze...

Visibly display the location of the water in the world. Using 12 liters of water to represent the total amount of water in the world, the class measures out the water located in different areas, such as the ocean and ice caps. Class...

Water is the focus of an interdisciplinary unit that brings awareness to its daily use around the world and the importance of conservation. Worksheets challenge scholars to match words and definitions, trace, complete a maze, and solve a...

Water is something most of us take for granted. Explore the important aspects of water with a short video lesson. The instructor addresses the key instructional points of the NGSS standard ESS2C. He explains the complexity of the water...

What better time to reinforce a concept than when you're eating? Boost scholars' knowledge of the water cycle with an eye-catching placemat featuring playful raindrops and bright colors. 

Go on an incredible journey called the water cycle with a video that details the ins and outs of water, its various forms, and place on planet Earth. 

What do animals and humans have in common? We both build homes that are suitable for our means of living, of course! This is the focus of a video that compares how humans and animals change the environment around them.

How do living things change their environment? This is the focus of a video that describes how the building of communities and clearing of forests changes the types of living organisms that can thrive there.

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.

If the amount of freshwater in an ecosystem changes, in what way is the specific ecosystem affected? This is the focus of a video that discusses the importance of freshwater and how all ecosystems need freshwater to sustain life.

How do different animals access the small amounts of freshwater on Earth, in order to survive? This is the focus of a video that discusses how animals must adapt to surviving off limited amounts of freshwater present in their habitat.

Most of the water on Earth is found in our oceans; however, humans cannot survive on salt water. Instead, we need freshwater. So, what is freshwater and where does it come from? This is the focus of a video that discusses the differences...

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

With about 70% of the earth's surface covered in oceans, it's fair to say that we live in a very wet world. Young scientists gain a better appreciation of this fact as they use maps to identify the world's ocean basins in the first...

Help young scientists get to the bottom of the water cycle with this comprehensive earth science lesson. After first viewing and discussing presentations about the states of water and the water cycle, the class performs a series of...

Having fresh, clean drinking water is a privilege many people take for granted. Help raise awareness about the scarcity of water and the importance of conservation by discussing different ways water is used in everyday life. Brainstorm...
