History of Water Use in Hawaii

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...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Young surveyors look for patterns in water flow around campus. Using a map of the school (that you will need to create), they mark the direction of the path of water. They also perform calculations for the volume that becomes runoff. The...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Students investigate quality of water in a stream, lake, or pond by examining chemical, physical, and biological characteristics.

Actual stream water is analyzed in this environmental science activity. Participants measure water temperature and pH, and then survey the macroinvertebrates living in their samples. The data worksheet, troubleshooting tips, and...

Go with the flow and use a helpful resource. A set of two activities has learners investigate flow rates. They first determine the flow rate of a faucet by measuring how long it takes to fill a bucket. Using the results, they make a...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Students compare bottled water qualities to water found naturally in a pond habitat. They research their state's laws/regulations in regard to bottled water and study the advertising, cost, and quality of brands of bottled water. They...
