  • Fetal Pig Dissection Pigs are excellent and engaging specimens for studying mammalian anatomy. They exhibit hair, a muscular diaphragm, a 4-chambered heart, and mammary glands. View »
  • Bacterial Hydrolysis of Starch In this lab, students culture two bacteria on potato dextrose agar, which contains starch. When grown on potato dextrose agar, bacteria that can secrete amylase—an enzyme that hydrolyzes starch—create a zone around their colonies in which starch is absent. When the agar is flooded with iodine solution, most of the plate stains dark blue–black, but clear areas are left around colonies that secrete amylase. 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 »
  • The Effects of Cell Cycle Deviation on Cancer Development Use Hudson Alpha's Newest Kit to demonstrate chance mutations and randomization in resulting in cancer. View »
  • 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 »
  • Bacteria: The Citrate Test In this lab students perform a test on two different bacteria to determine whether the organisms can use citric acid as their sole carbon source. The citrate test is often performed as part of the IMViC (Indole, Methyl Red, Voges-Proskauer, and Citrate) series of tests used to differentiate common species of enteric bacteria. View »
  • Introduction to Prokaryotes: Bacteria What are bacteria? In this introductory lab students make smears of bacteria on microscope slides from pure cultures, perform a simple stain, and observe their stained slides under a microscope View »
  • Introduction to Prokaryotes: Cyanobacteria In this lab students observe two examples of cyanobacteria and make a simple comparison to a eukaryotic green alga. View »
  • Discover Similar Functions in Plant and Animal Tissues Use this handy chart to draw parallels between structures and their functions in plant and animal tissues. View »
  • Human Body: Integumentary System Teach the role of the integumentary system with this infographic. 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 »
