Students in Mr. Morris’s science class at Darby High School have been identifying the differences between eukaryotic and prokaryotic cells. Until today, they had only looked at prepared slides of individual cells and tissues. Today they viewed eukaryotic organisms as single-celled to multicellular organisms. The students could see microorganisms feeding on green and brown algae, and they discussed what would happen if we lost any of these organisms in the food chain and how it would disrupt their entire ecosystem. Experiences like this they will remember and can continue to revisit as they learn about ecology later in the school year.
