Freshwater Habitats
Middle schoolers take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their...
Curated OER
Pond and Pond Organisms
Students explore pond ecosystems. In this pond organism activity, students will use pond water and a plastic bad in order to locate and identify freshwater organisms. The activity is designed for younger grades, but includes an...

Missing Macroinvertebrates - Stream Side Science
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...
Curated OER
Microscopic Water Life
Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...
