Stream Scanners

Do golf courses affect the water organisms in nearby streams and ponds? Small groups collect samples of water upstream and downstream from a golf course and analyze the macroinvertebrates found and the stream index values of the two...

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...

Here is an excellent lesson plan on the water cycle and the states in which water exists. Learners identify the features of the water cycle, describe how water changes form, and look at ways that people affect the natural movement of...

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.

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

Students perform an experiment to measure the density of tap water vs. salt water.

The goal of this collection of lessons is to make middle schoolers more aware of the ways in which they are dependent upon water to maintain their standard of living. Learners compare water use in Lesotho to water use in the United...
