  • Introduction to C-FERN® Teaching the basics of plant biology and capturing students' interest can be a daunting task. But C-Fern offers a dynamic new approach to teaching the basic aspects of plant biology. View »
  • Meiosis and Genetics In this lab, students investigate how the events of meiosis relate to Mendelian genetics. View »
  • How DNA is Packaged (DNALC Video) DNA contains all of the genetic code for a living organism, but how does all that information fit in such a tiny package. This 3D animation will show you how a chromosome consisting of one continuous thread-like molecule of DNA coils up and contains the buidling blocks of life. View »
  • Easy Variation and Natural Selection Lessons with Wisconsin Fast Plants® Seed Disks Explore a technique that makes teaching variation and natural selection lessons with Fast Plants® easier than ever. In this activity, students examine the effects an abiotic environmental change (salinity) has on an experimental plot of Fast Plants®. Includes detailed background information and instructions.

  • Sense of Smell and Olfactory Fatigue In this introductory activity, students use fragrant oils to determine the time of olfactory fatigue for both of their nostrils and examine the link between smell and memories. 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 »
  • Introduction to Biotechnology: An Essential Curriculum, Page 1 Page 1 This essential curriculum for introductory biotechnology covers DNA structure and function, basic lab techniques, transformation, electrophoresis, restriction analysis, PCR and sequencing, bioinformatics, and bioethics.

  • Teach Life Cycles with the Tobacco Hornworm Want to bring more excitement and wonder into your classroom as you teach life cycles in the spring? Bring in something new and different—something that may be the highlight of your semester. View »
  • Demonstrating Cellular Respiration and Fermentation Use this demonstration to show the big picture of aerobic cell respiration (with germinating seeds) and fermentation (produced by yeast). 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 »
  • 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 »
  • 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 »
