  • Bacterial Motility In this lab, students perform two exercises that investigate microbial motility. One is on a microscopic level, using the “hanging drop” slide preparation method to directly observe motile cells. The second exercise is on a macroscopic level and involves inoculating motility test media. View »
  • Snakeheads Invade the United States Teach your students about the challenges nonnative species pose by focusing on a current example, the northern snakehead fish. Native to China, Russia, and Korea, this fish has established breeding populations in several states. Find out how this might have happened and what scientists are doing about it. View »

  • Introduction to Feeding Preferences in Caenorhabditis elegans The nonparasitic soil nematode Caenorhabditis elegans has served as a model organism for research scientists since the 1960s. This lab introduces students to the organism and provides them with the tools necessary to perform simple experiments. View »
  • Bacteria: The Indole Test In this lab students perform a differential test to distinguish bacteria based on the production of indole. Bacteria are grown on media containing tryptophan and then treated with Kovac’s reagent. If they possess the enzyme tryptophanase, the bacteria can metabolize tryptophan into indole, pyruvic acid, and ammonia. View »
  • Copying Nature’s Success: Teaching Students About Biomimetics Ready to create a model home that draws on biomimetics? In this activity, students research, design, and build structures that incorporate ideas inspired by the natural world. View »
  • Biology in the Movies See how you can use movies to facilitate engaging learning experiences for your students. Each suggestion includes a brief synopsis and talking points. Here’s to making your biology lessons even better than before. View »
  • Science Notebook: An Owl Pellet Inquiry This introductory owl pellet dissection is a springboard for teaching the techniques of using a science notebook while having students engage in the scientific practices. View »
  • Isolating Bacteria from a Mixture How does a microbiologist isolate bacteria from a sample? In this lab students practice streaking a plate to isolate a single species of bacterium from a known mixture. View »
  • Introduction to Prokaryotes: Archaea In this lab, students are introduced to Halobacterium, a representative of the Archaea, one of the three domains of life (along with Bacteria and Eukarya). View »
  • Bacterial Growth on MacConkey Agar In this lab students culture three bacteria on nutrient agar and MacConkey agar and record the results. View »
