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...

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.

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...

Sixth graders investigate the amount of Earth that is covered by water. In this water consumption lesson, 6th graders discover that only a small portion of Earth's water is consumable due to pollution and other contaminants. Students...

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...

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...

Some aquifers took thousands of years to collect water, yet they have been depleted in only a hundred years. Viewers learn about where humans use water and the serious concerns for the future of the water supply in the second of 10...

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

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...
