Measuring the pH Value of 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...

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

Is the golf course causing issues in the stream? Find out with a resource that has groups perform chemical water tests to analyze the effects of a golf course on a stream. Pupils collect water above and below the course and analyze the...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

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...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th lesson in a series of 21 has scholars use the ICESat data to understand the ice mass...

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.
