Water Purification

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

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...

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...

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 filtration...

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...

A wrap-up to the unit, young environmentalists discuss and write about the difference in perspectives of a water keeper and water treatment engineer. 

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

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...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

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...
