Scholars build a simple filtration system to remove impurities from muddy water and rate the filtered water to a grade of clarity scale. The focus is on teamwork and problem solving. This instructional activity would be effective in your...

Young scholars study the process of water filtration in a three-part STEM lesson. After analyzing samples of dirty water, teams design and build their own filtration systems and measure their efficiency.

Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...

Students work together to examine the role of water in their lives. They discover the process to clean water so it is clean for one to drink. They explore the role of environmental engineers and their problem of getting clean water to...

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

Students investigate different methods (aeration and filtering) for removing pollutants from water. They design and build their own water filters. Students identify the pollutants in a water sample using sight and smell, explore what...

Learners explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they investigate filtration and aeration processes as they are used...

Learners work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Learners explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

Students investigate how engineers design methods of removing particulate matter from industrial sources to minimize negative effects of air pollution. In small groups they design and construct a filter with the goal of removing pepper...

Students will learn about the importance of water and the role it plays in our lives. Students will be exposed to what must occur each day so that they can have clean water.

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental...

In this instructional activity, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate...

Student teams practice water quality analysis through turbidity measurement and coliform bacteria counts. They use information about water treatment processes to design prototype small-scale water treatment systems and test the influent...

Students learn about water quality testing and basic water treatment processes and technology options. Biological, physical and chemical treatment processes are addressed, as well as physical and biological water quality testing,...
