  • Decomposition by Physarum polycephalum Observe the phenomenon of the plasmodial form of Physarum polycephalum as it streams in search of a food source. Essential question: What role do decomposers play in an ecosystem? View »
  • Science Notebook: An Owl Pellet Inquiry This introductory owl pellet dissection is a springboard for teaching the techniques of using a science notebook while having students engage in the scientific practices. 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 »
  • 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 »
  • 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 »
  • Hydroponics Using a nutrient-rich water solution and a unique, time-tested approach, you can successfully grow plants with no soil. In a hydroponic system, water does the work. Find out more about this fascinating method and the advantages that make it both appealing and effective. 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 »
  • Snakeheads Invade the United States Teach your students about the challenges nonnative species pose by focusing on a current example, the northern snakehead fish. Native to China, Russia, and Korea, this fish has established breeding populations in several states. Find out how this might have happened and what scientists are doing about it. View »
  • Introduction to Feeding Preferences in Caenorhabditis elegans The nonparasitic soil nematode Caenorhabditis elegans has served as a model organism for research scientists since the 1960s. This lab introduces students to the organism and provides them with the tools necessary to perform simple experiments. View »
