  • 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 »
  • Introduction to Planaria In this lab, students examine the anatomy and behavior of the planarian, a simple animal with bilateral symmetry. 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: 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 »
  • Bacteriophages in Human Disease: Friends and Foes Help your students understand the connection between bacteriophages and human disease. This scholarly overview explores how bacteriophages have helped and hindered humans in their quest to overcome certain diseases. Use it as assigned reading or to kick off a classroom discussion.

  • Bacterial Hydrolysis of Casein In this lab, students culture two bacteria on skim milk agar. The protein casein gives milk its white color. Some bacteria secrete protease enzymes that can hydrolyze casein. When these bacteria are grown on skim milk agar a clear area develops around the colonies, indicating that casein has been hydrolyzed into its component amino acids. 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.

  • Human Body: Nervous System Teach the functions of the central and peripheral nervous systems with this infographic. View »
  • Introduction to Invertebrates In this lab, students study representatives of several invertebrate groups. View »
  • Dissections in a Flipped Mastery Classroom Dissection plays an essential role in every anatomy and physiology class. As a teacher, you know it’s valuable, but do your students? Show them the value of performing dissections and give them a learning experience that’s authentic and engaging when you use the flipped-mastery approach. 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 Sterile Technique In this lab, students practice transfer of a bacterial culture using sterile technique. View »
