Product Details

Students will determine the presence or absence of coliform bacteria (indicative of the presence of untreated sewage and potentially pathogenic bacteria) in water supplies. By observing a dramatic color change that occurs in a lactose broth medium, students will determine whether coliforms are present. Includes 25 tubes of lactose broth medium with chlorophenol red indicator, sterile transfer pipets and instructions.

Performance Expectations

MS-LS2-1: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
MS-ESS3-4: Construct an argument supported by evidence for how increases in human population and percapita consumption of natural resources impact Earth’s systems.
HS-LS2-3: Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
HS-LS2-4: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
