Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

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...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

In this water pollution and filtration lesson plan, 5th graders read the story 'Saving Salila's Turtle' and discuss the impact pollution has had on the Ganges river. Students work in groups to brainstorm different types of water...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Here is a fantastic experiment-based lesson on water conservation, waste, and filtration. The lesson plan is well-developed and provides background information, discussion leads, and six scripted lab activities anyone can do. The class...

How can everyone in the world have access to clean drinking water? Throughout the instructional activity, learners read about and listen to how water is filtered, what the filtration process removes, and  the best ways to filter....

Drinking clean water can be taken for granted. Explore the process and high cost of filtering water with a water pollution and filtration activity. Young scientist build a filtration system to filter polluted water, examine the economics...

Learners design water filtration systems. They draw sketches and write paragraphs about their systems. After presenting their systems to the class, each group then builds their system and determines its effectiveness for purifying...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

Students observe a precipitation and neutralization reaction and learn to filter the products of the precipitation reaction. In this precipitation and neutralization lesson plan, students create curds and whey using milk and vinegar....

Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

Pupils brainstorm the different characteristics of potable water. In this general science lesson, students test several water samples and hypothesize which samples and brands they are. They discuss where drinking water came from and...

Students determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.

Students use field practices to clean foul water, they comprehend the differences in solution and solutes. They work in groups and discuss the lab instructions. Students start with oil-water separation technique. They complete a...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

Chemistry explorers prepare a crystalline derivative and find its melting point. Once they discover the melting point, they can identify whether the substance is pure or an aldehyde or ketone. This outstanding laboratory activity helps...

Students examine various types of household materials for their usefulness as filters. They work together in teams to design a filtration system that produces the cleanest water in the shortest time.

Tenth graders use a classification key to identify organisms.  In this classification lesson plan students identify freshwater species of fish and document their observations. 

Learners examine how river travel affected the Lewis and Clark expedition. They define gravity, slope, and velocity, conduct a river formations experiment, complete an activity sheet, and watch a video about Lewis and Clark.

Young scholars conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield...

In this instructional activity students will learn about water treatment and what happens to water when it goes down a toilet and drains into sewers. Through further investigation students will understand the relationship between 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...

For this lesson plan, students use different types of filters to separate the mixture. This lab requires the students to use engineering skills to solve a real-world problem of filtering water.
