  • Pill Bug Behavior Choices This introductory investigation into animal behavior uses pill bugs and choice chambers. Students begin with an experiment to test how pill bugs respond to humidity and can go on to design an inquiry to test another environmental factor. View »
  • Invertebrate Biodiversity and Abiotic Factors Understanding the relationships between biotic diversity and abiotic factors in an ecosystem can be a difficult task. Using soil invertebrates, students can identify both the number of species present in a soil sample and the number of individuals within a species. View »
  • Carolina's Recommended Reading for AP® Biology Teaching AP® Biology this year? Go beyond the textbook and take students on an exploration of key concepts with these teacher-tested and recommended books. 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 »
  • Copying Nature’s Success: Teaching Students About Biomimetics Ready to create a model home that draws on biomimetics? In this activity, students research, design, and build structures that incorporate ideas inspired by the natural world. View »
  • Plant Biodiversity Field Activity This field activity introduces students to biodiversity through the study of plants and animals in a designated area. But here’s the twist—instead of using a quadrat to designate the area of study, students use a Hula Hoop® instead. 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 »
  • 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 »

  • Infographic: What's Your Blood Type? Use this exciting infographic as a teaching aid for your classes as your students discover the ABO/Rh blood groups. 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 Invertebrates In this lab, students study representatives of several invertebrate groups. View »
