Introductory Microbiology

AP biology and college microbiology classes benefit by completing this seven-page worksheet on microbes. An exhaustive set of questions addresses the characteristics and reproduction of viruses, classification and uses of bacteria, and...

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

The microbes are gathering, organizing, dividing, reproducing, forming communities, and cooperating. We're surrounded but we can't even see these tricky little organisms. Use this short video to introduce viewers to biofilms and then...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

If you do not mind wading through unrelated headings (This is not for a physics or STEM course, as it states.) and content (The lesson opens with an article about neurology, not halophiles.), then you will find a valuable resource on...

Young scientists enter the world of microscopic organisms with this introductory presentation on bacteria. Starting with a basic definition of these single-celled organisms, the presentation continues on to explore different types of...

Join the fight against bacteria. An open investigation shows pupils different aspects of antimicrobial substances, such as disinfectants, deodorants, or plant oils. They design and conduct their own experiments on the effectiveness of...

Three episodes explore pondlife with microbiologist Sally Warring from the American Museum of Natural History. Videos give scholars an up-close look into the microbes that live among pond scum, algae, and moss while the host offers...

Young scholars determine the optimal living conditions for yeast and apply these results to microbes in food. In this microbiology lab lesson, students observe the reaction of yeast to elevated temperatures. They relate these results to...

Peas spoilage hot, peas spoilage cold: examine the bacterial growth on newly defrosted peas versus peas that have been defrosted for 24 hours. Using the session one questions in the "Microbes and Food Spoilage" PDF, learners will make...
