  • Real-World Classroom Connections: Hospital-Acquired Infections and Super Bugs Teachers are always looking for new ways to engage their students and create intrigue in the classroom. There is no better means to accomplish this task than by building a unique lesson plan that ties together real-world examples, inquiry investigations, and Glo-Germ™. View »
  • Insects: Friends or Foes? The Many Roles of Beneficial Insects You probably don’t go a day without eating or wearing something that an insect has produced or pollinated. Learn more about the many ways insects benefit humans, from food production to health care. View »
  • Science of Chocolate Many people enjoy the taste of chocolate, but taste isn't all there is to know about the well-loved flavor. There is also the engaging science of chocolate that you can share with your students. View »
  • Natural Selection in 50 Minutes Help your students understand why common misconceptions about natural selection aren't true using some craft store beads, our instructions, and 50 minutes. View »
  • Investigating Seed Germination The story of how a seed becomes a plant is fascinating to young students. These activities for grades K-4 will help your students explore the process of germination, seed structure, and early seedling growth. View »
  • Chicken Wing Musculature Explore the structures and functions of muscle tissue and practice dissection techniques with this activity. View »
  • Explore Animal Diversity with Inquiry-Based Dissection Comparative anatomy is an excellent approach to study the diversity of animal adaptations. View »
  • Biodiversity of Soil Animals In this lab, students use a Berlese funnel to take samples of soil-dwelling animals, and then compare the numbers and kinds of organisms collected from different habitats. View »
  • A Sexual Experience? There are 2 primary forms of reproduction: asexual and sexual. While the majority of the animal kingdom reproduces sexually, many reproduce asexually—and some organisms have the ability to perform both ways! View »
  • Strawberry DNA Extraction Introduce students to DNA with this activity. A discussion of how this DNA extraction procedure works might also touch on the plant cell wall, the cell membrane, and DNA's lack of solubility in ethanol. Includes materials list and step-by-step instructions. View »
  • Hydroponic Nutrient Solution After a structured investigation of a hydroponic technology, students design an experiment to test different nutrient solutions. View »
  • Bacterial Hydrolysis of Lipids In this lab, students culture two species of bacteria on agar medium that contains an emulsion of plant oils and the dye, sprit blue, which forms a complex with the triglycerides of the oils and gives an opaque blue color to the agar. Colonies of bacteria that can secrete lipase, an enzyme that hydrolyzes triglycerides, develop a light area or “halo” in the surrounding medium, due to the diffusion of lipase into the medium and the resultant breakdown of the oil/spirit blue complex.
