Introduction to Protists: Euglena
Carolina LabSheets™ Overview In this lab, students observe Euglena, a protist that combines some characteristics of animals with the plant-like ability to photosynthesize. Traditionally, Euglenas were classified under Domain Eukarya, Kingdom Protista, and Phylum Euglenozoa (sometimes Euglenophyta). However, it is widely recognized that Protista is not a natural grouping. Currently, Euglena is classified in the […]

Introduction to Prokaryotes: Bacteria
Carolina LabSheets™ Overview In this lab students are introduced to the Domain Bacteria (Eubacteria). They will make smears of bacteria on microscope slides from pure cultures, perform a simple stain, and observe their stained slides under a microscope. The stained slides are best observed at 700–1000× with oil immersion; however, they can be viewed under […]
Isolating Bacteria from a Mixture
Carolina Labsheets™ In this lab, students are introduced to a basic technique used in the study of bacteria: isolating a single species of bacterium from a mixture. Environmental surfaces are often sampled and the samples streaked on plates to isolate bacteria. In this activity, students practice the technique by using a mixture of bacteria of […]
