Microbes and Our Food
Young scholars investigate foodborne illnesses and involved microbes. They identify major pathogens and then research and explain how they contaminate foods and how people are affected.
Curated OER
Bacteria's Role in Food
Young scholars grow bacteria cultures on agar in petri dishes and do a plate count. They participate in a yogurt making lab to see how bacteria produce lactic acid. They prepare a recipe and identify fungi, fermentation and the role of...
Curated OER
Yeasts and Molds
Students investigate the characteristics and nature of yeast and molds help to explain how these microorganisms affect food production. They experiment with yeast in sourdough in preparing sourdough pancakes.
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
Microbes
Microbiology beginners feed different sweetening agents to yeast and measure carbon dioxide production to estimate energy contained in each. They set the trials up in zip-top plastic baggies and then measure gas volume by water...
Curated OER
Hand washing Laboratory Activities
Young scholars are exposed to the benefits of many antimicrobial soaps to prevent infections. In the food-service industry, studies indicate that inadequate hand washing and cross-contamination is responsible

Microbial Spoilers: The Impact of Microorganisms on the Shelf-life of Milk
Students are inroduced to a commonly used microbial culturing technique. They explore the role of microorganisms in determining the shelf-life of food products.
Curated OER
Stream Quality Assessment
Pupils investigate many of the factors that affect water quality. They take measurements and water samples at a local stream and evaluate the health of their community's watershed. They write a report detailing their findings.
Curated OER
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.
