• Owl Pellet Food Webs: A Model of Energy and Mass Transfer Explore the phenomenon of owl pellets and construct a model food web for barn owls with this activity. Guiding question: How do energy and mass flow through a food web? 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 »
• What’s the Genotype? In this lab students are introduced to the testcross and its use in revealing whether an organism is homozygous or heterozygous for a trait. View »
• Investigating Hatching of Brine Shrimp Eggs In this lab students study the hatching of brine shrimp eggs and design an experiment to see what factors influence hatching. View »
• Invertebrate Biodiversity with Berlese Funnels Using soil invertebrates, students identify the number of species present in a soil sample and the number of individuals within a species. With some simple math, they can then calculate the density of invertebrates in a plot. 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 »
• Living Organism Care Guide: Brine Shrimp Get care instructions for brine shrimp (Artemia salina), including details on housing and feeding, information about the organism, related resources, and FAQs. View »
• 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 »
• 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 »
• Gene Interaction with Drosophila How do genes interact in the inheritance of traits? Find out in this intriguing study of the inheritance of eye color in Drosophila. View »
• Living Organism Care Guide: Sea Urchins for Embryological Studies Get care instructions for sea urchins, including details on preparation and maintenance, information about the organism, related resources, and FAQs. 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 »
