Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school instructional activity has clearly described activities, and...

As a way to quickly expose your science class to six different freshwater projects around the world, this lesson plan assigns each small group to research and share one. All of the information is gleaned from the website for CH2M HILL, a...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

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...

Your mission, should you choose to accept it, is to take your class on an underwater adventure. The final installment in a seven-part series involving salt and freshwater bodies takes junior oceanographers below the surface in...

What's in the water? Encourage your class to further explore this question and learn about pond ecosystems, food chains, and food webs as they complete this hands-on activity. They view the environment from a new perspective...

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...

Young explorers study the scarcity and importance of a continuous supply of fresh water in Cape Verde. They research the five main ways that fresh water is obtained in these countries. Each research group prepares a presentation, and...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

Water covers around 75 percent of the earth, yet humans struggle to find enough fresh water to live. The fourth of 10 lessons focusing on Fresh Solutions requires brainstorming. Young scientists consider various problems related to fresh...

How did the stickleback fish, which was once ocean bound, evolve to be able to persist in freshwater lakes? Hear from the scientists who identified the genes and related switches that allowed these survivors to adapt. In addition to the...

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson plan in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem....

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

How much water does it take to brush your teeth? How about to wash your clothes? Perform an experiment that measures water usage in everyday tasks and compares them to the days before indoor plumbing, specifically the California...

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.

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

A read-aloud anthology explores various habitats and the animals that inhabit them, from the Artic to the desert, the forest, and bodies of water. First graders listen to and discuss texts and complete word work. Each lesson offers...

Hydrology hopefuls learn about their local watershed. Through discussion and online interactives, they see that their habits affect the water supply. The lesson plan concludes with a pledge to filter out bad water usage habits. It makes...
