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

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Explore the makeup of the earth's atmosphere. Using the set of specific experiments, pupils examine the main elements and compounds present in the atmosphere. Their study extends to investigate the effects of atmospheric...

How do we protect crops and protect the environment at the same time? Using reading materials, learners explore the history of the use of pesticides and biocides. They create a timeline and then explore the current practices.

Auntie Litter is here to educate young scholars about water pollution and environmental stewardship! Although the 15-minute video clip is cheesy, it's an engaging look at the water cycle and conservation. Learners start by illustrating...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

Young ecologists investigate some of the many ways that human activities adversely affect the environment. After identifying the main types of pollution (air, water, soil), 3rd graders fill in a Venn Diagram by pasting cut-out pictures...

Students use a hypothetical scenario to investigate inhalation of an airborne pollutant and ingestion of a waterborne pollutant. They work in pairs, investigating differences in overall exposure to contaminants by calculating inhalation...

Students investigate how pollution affects lung health. In this pollution and lung health instructional activity, students build lung models from a soda bottle and balloons, and then discuss how the emissions from fossil fuels can...

Students identify the different layers of the atmosphere. They examine the different types of air pollutants. They also discover laws in effect that work to protect the environment.

What does a beautiful sunset have to do with the atmosphere? An inquiry-based lesson has learners make observations about the visibility and color of the sky during different time periods. They then relate their observations to...

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 explore air pollution. In this ecology and air pollution instructional activity, students perform an experiment in which a Vaseline coated lid is placed inside and outside the classroom. Students make predictions and then record...

Students recognize whether one wants to drink water, swim in it, or for the health of the organisms living in it. They prepare different water samples to observe and collect samples regarding the water quality.

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...

Students conduct experiments to illustrate global warming. In this air pollution lesson, students first examine how a layer of greenhouse gasses might impact the earth's atmospheric temperature, then evaluate how the layer of gasses...

Students discuss how groundwater becomes polluted. In groups, they design and create models of groundwater pollution sources. They demonstrate to the class how the water may become contaminated from local and nonlocal pollution sources.

Pupils participate in many activities examining air quality. They examine the purpose of a greenhouse and make predictions. They also collect data and make graphs and charts.

Students seek solutions to environmental problems. They discover how to conserve and protect natural resources. They examine the role of acid rain on plants and discover how to filter pollutants.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...

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.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...
