Bacteria in Milk—
Student Laboratory Kit
By: Jeannette Miller
Schalmont High School, Schenectady, NY
How much bacteria grows in refrigerated milk? What happens if milk stands out for a day or even for a few hours? Students test refrigerated milk, boiled milk and room-temperature milk to determine and compare their relative bacterial conditions . Students use the resazurin color reac- tion to demonstrate the relative amounts of bacteria in the various milk samples . Kit materials include the test tubes, powdered milk and the resazurin test solution .
Complete for 30 students working in pairs. Super Value Kit is complete for five classes of 30 students working in pairs.
Bacteria Study Kit
Illustrate different bacteria using this informative study set . Includes six microscope slides in a plastic box, three overhead color transparencies, and detailed student worksheets . Two slides are carefully stained to show mouth bacteria and three smears of typical bacteria: cocci, bacilli, and spirilli . Other slides show Staphylococcus aureus and Escherichia coli . Bacillus subtilis, hay bacillus, is presented with a smear of bacilli and spores . Spirillum volutans, a large species from putrid water, is also part of the set . All materials come packaged in a convenient storage box .
Bacteria Soil Ecology—
Student Laboratory Kit
By: David Brock and Mariel Torres,
Roland Park Country School, MD
and Katie Loya, University of Maryland, MD
A great introduction to soil microecology and how soil influences all multi-cellular organisms in an ecosystem . How much bacteria is in your soil? What is the purpose of bacteria in soil? Students will use PetrifilmTM strips and serial dilutions of soil to answer these questions . This easy-to-perform experiment produces excellent results . Students will have the opportunity to create their own hypothesis, design and perform experiments, and analyze and interpret data . Includes reproducible student handouts, complete Instructor’s Notes, and all consumable supplies needed to perform the lab .
Complete for 24 students working in pairs.
