  • Isolating Bacteria from a Mixture How does a microbiologist isolate bacteria from a sample? In this lab students practice streaking a plate to isolate a single species of bacterium from a known mixture. 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 »
  • Wisconsin Fast Plants® and Product Testing In this inquiry activity, students conduct experiments to determine if a commercial product effects the germination of Wisconsin Fast Plants® seed. In doing so they practice basic science skills including collecting and graphing data, interpreting data, and doing serial dilutions. View »
  • An Inquiry into Seed Germination This NGSS-aligned activity is a student inquiry into factors that affect seed germination.Use it as an introduction for plant studies in biology or as an environmental impact investigation in earth science, environmental science, or agricultural science. 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 »
  • What Do Plants Need To Grow? Explore the phenomenon of plant growth with this guided inquiry activity. Students use seed disks to determine the amount of sunlight and water plants need to grow. For grades K-2. View »
  • Materials Plants Need to Grow Examine the phenomenon of plant growth by designing and carrying out an experiment to show that plants need air and water to grow. For grade 5. View »
  • Biology in the Movies See how you can use movies to facilitate engaging learning experiences for your students. Each suggestion includes a brief synopsis and talking points. Here’s to making your biology lessons even better than before. View »
  • Embryology with Rhabditis In this lab students observe cleavage of fertilized eggs of female Rhabditis. View »
  • Video: Comparing DNA Sequences This engaging video by science teacher Paul Andersen shows you how to compare DNA sequences to understand evolutionary relationships. View »
  • Using pClone Red for a Science Fair Project on Bacterial Gene Expression The emerging field of synthetic biology attracted the attention of one high school student planning his science fair project. His research—and its award-winning results—may suggest new ways that you can explore gene expression with your students. View »
  • Introduction to Prokaryotes: Archaea In this lab, students are introduced to Halobacterium, a representative of the Archaea, one of the three domains of life (along with Bacteria and Eukarya). View »
