  • 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 »

  • 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 »
  • 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 »
  • Constructing a Cladogram with Hydra, Planaria, and Daphnia In this lab students compare the body structure and functions of three invertebrates to that of a vertebrate. They use their data to construct a cladogram. View »

  • Infographic: Bring Your Genetics Lessons to Life with Model Organisms Carolina offers unique opportunities to work with model organisms—such as genetic corn (Zea mays), Wisconsin Fast Plants® (Brassica rapa), and fruit flies (Drosophila melanogaster)—in your genetics labs. View »
  • Mitosis Match Up: Student Activity Sheet With this activity, students identify and label pictures of plant cells in varying phases of the cell cycle. View »
  • Optics of the Human Eye A cross-curricular lesson in biology and physics allows students to make a simple model of the human eye. Students investigate how geometric optics can be applied to this complex, biological structure in order to describe how the images we see are formed when special tissues in our eye, the cornea and the lens, refract the light entering the pupil to create an image on the back wall of the eyeball (the retina), like a miniature, organic movie projector.
