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...

Learners gain understanding of several of the biogeochemical processes in microbial mats. They acquire knowledge of the different roles of organisms in a microbial mat ecosystem. They understand how microbial mat ecosystems contributed...

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...

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....

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...

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...

Students explore how to extract plant fibers from the flax plant Linum usitatissimum in the process of making linen fibers. Doing so spark interest in the importance of microbial action on the spread of human culture and civilization.

Students listen to a lecture on four factors that influence microbial growth and they discuss how to test the optimal growth requirements of a designated bacterium. They design and carry out laboratory investigations to test growth of...

Substances that decompose with the help of living organisms do so at different rates. Scholars experiment with Winogradsky columns to determine the rate of decomposition, the oxygen and sulfide content changes, and bacteria levels. The...

Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

In this biology worksheet, students take part in an examination of the graphic organizer to determine the different types of environments and how they effect the survival of microbes.

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...

Learners conduct an experiment to investigate the rate of microbial growth at different temperatures. Students predict what will happen to the food at various temperature and test their hypotheses. Learners describe the differences in...

Students view a Reading Rainbow video on germs and discuss microbial diseases. They grow cultures of Staphylococcus aureus and then estimate and graph the count for their own bodies and those of the class.

Students identify the different biogeochemical cycles on Earth. For this biology lesson, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.

Students are inroduced to a commonly used microbial culturing technique. They explore the role of microorganisms in determining the shelf-life of food products.

Students use easily obtained materials to study ecological succession in a microbiological community. This investigation is appropriate for a variety of age groups. Elementary Students be fascinated by the changes occurring over time...

Students study data from a USDA catfish pond. They look for microbial populations and chemical concentrations in the runoff to determine the effectiveness of filter strips. They use their knowledge of biogeochemical cycles to explain the...

Kids compare what printed text looks like with the naked eye and under magnification. They discuss the extremely small scale that must be used to measure the size. They learn about the micrometer unit, then draw scale models of a variety...

Students discuss sicknesses and how medications have been designed to combat microbial illnesses. They review microbial groups and learn more about treatment of microbial illness. After viewing the lab students conclude that antibiotics...

Students complete a WebQuest on viruses, bacteria, and protists. They explore various websites, and answer discussion questions.

Students explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth from...

Students explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.

Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.
