  • Introduction to Hydra This lab introduces students to Phylum Cnidaria. The activity also serves as an introduction to animals. View »
  • Next Generation Dissections Dissection can and should be part of your implementation of 3-dimensional learning. Carolina can help you make this transition with updated kits and resources. 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 Planaria In this lab, students examine the anatomy and behavior of the planarian, a simple animal with bilateral symmetry. View »
  • Bacterial Growth on MacConkey Agar In this lab students culture three bacteria on nutrient agar and MacConkey agar and record the results. View »
  • Bacterial Hydrolysis of Lipids In this lab, students culture two species of bacteria on agar medium that contains an emulsion of plant oils and the dye, sprit blue, which forms a complex with the triglycerides of the oils and gives an opaque blue color to the agar. Colonies of bacteria that can secrete lipase, an enzyme that hydrolyzes triglycerides, develop a light area or “halo” in the surrounding medium, due to the diffusion of lipase into the medium and the resultant breakdown of the oil/spirit blue complex.

  • Teaching About the Human Body Systems Are you ready to enhance your body systems curricula? Check out our free resources for teaching body systems. Pair them with models, dissection specimens and supplies, safety equipment, and more. 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 »
  • The Dogfish Shark—Structure and FUNction! Use this simple guide to connect form and function during your next dogfish dissection activity. View »
  • Using Algae Beads as a Model for Photosynthesis Introduce students to photosynthesis with fresh water algae. By creating algae beads (made of algae and sodium alginate solution), they indirectly observe the change in concentration of oxygen in beads that are exposed to different amounts of light. View »
