Measuring with water

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

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...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

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...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

Students investigate the water cycle by performing a simple hands-on activity using a plastic container, plastic cup, a rock, and a reflector lamp. They observe the model and measure the water level from time to time.

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...

How can researchers measure the amount of water on Jupiter? Through a thought-provoking THNKR "Why with Nye!" video, young space scientists search for the universal solvent on a distant planet. Topics include how scientists use visible...

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...

What a fresh approach to learning about water! Chef Jamika Pessoa explains the chemical composition of this vital compound, what happens when heat is added or removed, and how much water is contained in different organs and...
