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...

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...

Send youngsters home to survey how they use water in their homes. Then bring them together to discuss which uses are essential for our health and which are not. A helpful video offers teaching tips for this lesson, and a presentation...

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

For anyone studying biochemistry, it is important to understand the amazing properties of water. Here, learners draw the water molecule and explain the bonds it is able to form. They undertake explanations of adhesion, cohesion,...

Across the top of the page is a large Z diagram representing varying degrees of acid-base equilibria. Advanced chemistry classes answer eight questions using the values listed for the H+ and the OH- ions that are part of the diagram and...

How much water does it take to brush your teeth? How about to wash your clothes? Perform an experiment that measures water usage in everyday tasks and compares them to the days before indoor plumbing, specifically the California gold...

Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.

Performing calculations is for more than just mathematicians — it's an important science skill, too. Demonstrate the pH calculations using the slide show resource. The final resource of a seven-part unit introduces young scientists to...

When environmental studies classes are preparing to sample water for quality, they need to know what factors to test. This collection of slides explains different water quality indicators and why each is important. Viewers will be able...
