Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson plan is...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

What's the best way to learn how watersheds work? Build one! Combining engineering, the water cycle, and ecology concerns, the activity is the perfect fit for an interdisciplinary unit. Teams construct a model watershed with simple...

Here is a 20-box bingo card to use when exploring ways that humans impact the environment. Various environmentally aware activities are listed in the boxes, and learners circulate the room to find someone who practices the different...

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Don't desert a resource on the desert! Scholars work in groups to build on their ideas from the previous lesson to design a sustainable guest village in the Saguaro National Park. Each group produces a PowerPoint presentation to share...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

Use these water-themed activity sheets to allow children to choose their own learning adventures.

Students keep track of their own water usage for one week, gaining an understanding of how much water is used for various everyday activities. They relate their own water usages to the average residents of imaginary Thirsty County, and...

In this activity, students monitor how much water is used if the water is left running while they brush their teeth. They use that information to calculate how much the whole family would use. They learn how much water can be conserved...

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as...

Students use a watt meter to measure energy input into a hot plate or hot pot used to heat water. The theoretical amount of energy required to raise the water by the measure temperature change is calculated and compared to the electrical...

Teachers can start this project at any time and no registration is required. Students collect data about water usage for themselves, their homes and their class. They analyze it, make predictions about it, and submit the data to the...

Students are introduced to the concepts of graywater and water reuse within households. They calculate the amount of used water a family generates in one day and use a model of home plumbing to find out how much graywater is produced in...

In this lab-based activity, the students will accomplish two sequential goals. The first goal is to understand the law of conservation of energy.The second goal is to use their knowledge in part one to determine the temperature of a hot...

From Shore to Sea: To survive in cold ocean environments an organism's body must be adapted to life under water. A body will cool very quickly when in contact with water. The body shape of an organism is one adaptation that helps to...

In this lesson, students read and analyze articles about the alkaline water in Lake Turkana in Kenya, and about a wind energy project near Lake Turkana. They then examine the many factors that must be considered when undertaking this...
