What are the Chemical and Microbiological Effects of Run-off from a Catfish Pond on the Surrounding Soil and Water?
Learners 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...
Curated OER
Microbiology Design Challenge
High schoolers discover dangers to human health by researching what's in our drinking water. In this water purification instructional activity, students discuss the conditions of water in undeveloped countries and why it is unsafe to...
Curated OER
Isolating Bacteria from a Mix Culture
Students isolate three species of bacteria using the plate streak method, implement sterile microbiology techniques, and produce pure cultures of each microorganism at the end of this exercise. They write a descriptive paragraph for each...
Curated OER
Helpful Microorganisms
Students study how some microorganisms are helpful and practical in foods. They work with microorganism in a number of food, such as yeast in bread and yogurt.
Curated OER
Factors Affecting Microbial Growth
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...

Should Soil Be Sterile?
Students determine if the sterilization of topsoil is beneficial to seed germination and plant growth. They grow plants alongside control groups, make and record observations of plant growth and measure plant biomass.

A Watershed Monitoring Module
Students explore the relevance of water quality monitoring in relation to a local wetland ecosystem. They conduct standard water quality tests using wet tests and CBL calculators and probes. Student record and interpret the results.
