  • Sheep Brain Dissection Introduce students to the anatomy of a mammalian brain with this activity. Includes a brief survey of the internal and external anatomy of the sheep brain and go-to dissection resources. View »
  • 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 »
  • Infographic: Human Body Systems Teach the main body systems with the help of this infographic. View »
  • Under the Skin—Mammalian Musculature Whether you’re teaching college-level anatomy and physiology, an advanced high school anatomy course, or a basic biology course, cat dissection is one of the best ways to help your students understand mammalian musculature. View »
  • Investigating Photosynthesis This video contains great activities you could use to teach photosynthesis! View »
  • Lumbriculus: Contraction Rate of the Dorsal Blood Vessel In this introductory physiology lab, students determine the contraction rate of the dorsal blood vessel of the blackworm Lumbriculus. Students then design and conduct an experiment to determine the effect of temperature change or chemical exposure on the contraction rate. View »
  • Introduction to Protista: Euglena Euglena was once studied as a simple animal by zoologists and as a simple plant by botanists. How does this protist combine some characteristics of animals with the plant-like ability to photosynthesize? View »
  • Using Planarian Reproduction as a Path to Hands-On Inquiry Learning When can you divide something and have 2 whole "somethings" left? To answer that question, engage your class with a study of how planarians regenerate when split into anterior and posterior halves. Students design and execute an experiment about this reproductive strategy. 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 »
  • Introduction to Photosynthesis Using Coleus Plants The simple exercises that students perform in this lab demonstrate that plants produce glucose through photosynthesis, that plants convert at least some of the glucose to starch, and that sunlight is a critical factor in photosynthesis. View »
  • Introduction to Fungi This lab introduces students to the Kingdom Fungi through study of two phyla, the zygomycetes and basidiomycetes. View »
  • Making 3D Phylogenetic Trees with Mobiles Students grow in understanding as they create 3-dimensional phylogenetic trees comprised of mobiles. And it’s done using easy-to-find, inexpensive materials. View »
