See the water filtration system up close with a fun science experiment. Young scientists work for several class periods to design a water filter using household objects, and then decide which filter material would be most effective...

Fifth graders investigate the how water becomes polluted and how it effects the environment, animals, and humans. They watch a video and conduct experiments.

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the lesson goes...

Students complete an experiment on water to study water quality. In this water quality lesson plan, students complete a taste test experiment about chemicals in water. Students then study their local water environments and recorded...

We are very dependent upon other life forms around us to survive. Here, scholars explore relationships in the ecosystem with the help of Auntie Litter and the pollution patrol. They imagine a world without grass, making connections to...

Students construct their own water filter to obtain clean water. In this filtration lesson, students produce tainted water in order to properly filter it with filtration devices made in class.

Create a simulation of acid rain in your classroom with lemon juice and bean plants to help kids study the effects of pollution on plants. In addition, learners will listen to a story and write responses based on guiding questions.

Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.

Students examine the environmental impact of global warming. For this environmental science lesson, students design and conduct an experiment about the effect of temperature on paramecia. They write a lab report about their experiment.

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Learners investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Students perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Students investigate healthy eating habits by researching livestock. In this food sustainability instructional activity, students research the negative impact factory farming has on our environment due to pollution. Students define...

Students examine the history of air pollution dating back to the Roman Empire. In groups, they research the different types of pollutants in the air and how they can affect the environment. They participate in various experiments to...

Fifth graders play a game in which they list as many environmental issues or terms in alphabetical order. They brainstorm ways they can save the environment and create a mural that displayed research found from the internet and Encarta.

Learners explore marine life by conducting a rubber duck experiment. In this water currents instructional activity, students practice identifying latitude and longitude coordinates on a map and define the currents of major oceans....

Students will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.

Ninth graders research the importance of maintaining an unpolluted source of water in their community. They brainstorm ideas on what they can do to help the problem. They can also write letters to their local politicians for help.

Ninth graders research the importance of maintaining an unpolluted water source in their community. They work together in groups and brainstorm ideas on what they can do to help. They can also write their local politicians.

Fourth graders examine aquatic orgnaisms and how enviromental chages affect them. This factors include: temperature, Ph, oxygen, nutrients, and pollutants. They also explore habitat quality (erosion). Students compile data and create...

Young scholars examine and plot atmospheric data on bar graphs.

Students discuss what a watershed is, complete online activities showing them how to take care of a watershed, and create a model of a watershed that they experiment with to see what happens when it is disrupted by civilization.

High schoolers explore how human beings affect the world's ecosystem by examining the affects of medication on daphnia, a small freshwater organism very sensitive to pollution. Students use a computer model to repeat the experiment and...
