Life Science

  • 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 »
  • Examples to Use When Teaching About Selection and Evolution: Fox Domestication and Poison Resistance in Rodents To make abstract science concepts more concrete, teachers often use real-life examples. But even classic examples can lose their appeal. Refresh your lessons on evolution and selection with 2 less well known examples. 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 »
  • Hydroponic Nutrient Solution After a structured investigation of a hydroponic technology, students design an experiment to test different nutrient solutions. View »
  • Bacterial Hydrolysis of Casein In this lab, students culture two bacteria on skim milk agar. The protein casein gives milk its white color. Some bacteria secrete protease enzymes that can hydrolyze casein. When these bacteria are grown on skim milk agar a clear area develops around the colonies, indicating that casein has been hydrolyzed into its component amino acids. View »
  • 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 »
  • 32 Standards Met with Wisconsin Fast Plants® Engage students and support NGSS with classroom-tested, tried-and-true Wisconsin Fast Plants®. A leading expert on the use of Fast Plants® in education recommends investigations and kits to support K–12 NGSS. View »
  • Embryology with Rhabditis In this lab students observe cleavage of fertilized eggs of female Rhabditis. 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 »
  • Bacterial Motility In this lab, students perform two exercises that investigate microbial motility. One is on a microscopic level, using the “hanging drop” slide preparation method to directly observe motile cells. The second exercise is on a macroscopic level and involves inoculating motility test media. View »
  • Bacterial Growth on MacConkey Agar In this lab students culture three bacteria on nutrient agar and MacConkey agar and record the results. 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 »
