Grade 8: Scientists Collect, Analyze Water Samples

Eighth graders wrapped up a biology unit this week with a field trip to collect water samples from a nearby pond. Back in the science lab, teacher Dan Barklund guided them to use microscopes and observe the biodiversity present in the microorganisms. "We looked for protozoans and other single celled organisms, and found quite a few!" says Mr. Barklund. These included Stentor, Paramecium, Diatoms, Rotifers, among others. In the coming weeks, students will use these specimens to learn about how these creatures move, produce energy, and reproduce by using various cell organelles.
