Seventh graders explore the micro world around them

Seventh graders in Mark DePew’s science classes at Lakewood Middle School spent a sunny day in May collecting water samples from the stream behind English Crossing Elementary. After learning the basics of using a microscope, the students spent a class period analyzing their samples to see how many specimens they could identify.

They found pond shrimp, decomposers, cyclops, spirogyra, and more. Students followed up the experiment later in the week by sketching one of the organisms. The seventh grade science classes have been studying ecosystems and the transfer of energy. This experiment allowed students to see that even the smallest things have energy that affects the whole community.
