Life Science

  • Introduction to Prokaryotes: Cyanobacteria In this lab students observe two examples of cyanobacteria and make a simple comparison to a eukaryotic green alga. 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 »
  • 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 »
  • Bacterial Hydrolysis of Starch In this lab, students culture two bacteria on potato dextrose agar, which contains starch. When grown on potato dextrose agar, bacteria that can secrete amylase—an enzyme that hydrolyzes starch—create a zone around their colonies in which starch is absent. When the agar is flooded with iodine solution, most of the plate stains dark blue–black, but clear areas are left around colonies that secrete amylase. View »
  • The Science of Fear You know that hair-raising feeling you get when you’re scared? By undergoing a specific physiological response, your body is primed to confront, and hopefully overcome, whatever scary situation you face. View »
  • Dissections in a Flipped Mastery Classroom Dissection plays an essential role in every anatomy and physiology class. As a teacher, you know it’s valuable, but do your students? Show them the value of performing dissections and give them a learning experience that’s authentic and engaging when you use the flipped-mastery approach. View »
  • Human Body: Integumentary System Teach the role of the integumentary system with this infographic. 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 »
  • A Brief Look at Cells: Shape and Function Discover morphologies of common cells and why they are shaped in such ways View »
  • What's Your Type? Using Carolina® Synthetic Blood in your classroom offers students the opportunity to conduct realistic blood typing activities without the associated risks. This activity includes a materials list and step-by-step instructions. View »
  • Bacteria: The Indole Test In this lab students perform a differential test to distinguish bacteria based on the production of indole. Bacteria are grown on media containing tryptophan and then treated with Kovac’s reagent. If they possess the enzyme tryptophanase, the bacteria can metabolize tryptophan into indole, pyruvic acid, and ammonia. View »
