Contaminated Drinking Water

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Young scientists create their very own aquifers in this science lesson on ground water. After learning about how some people get their drinking water from underground wells, young learners use sand, modeling clay, and aquarium rocks to...

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 lesson would be effective in your STEM curriculum...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

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...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt, and...

Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...

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

Often called the gift of nature, water is a valuable natural resource. A creative lesson examines the importance of water quality for both humans and agriculture. Scholars learn to view natural areas as filters for rainwater. They...
