Explore environmental health effects of the antimicrobial Triclosan

Explore potential environmental health issues associated with Triclosan, an antimicrobial agent found in a variety of consumer products.

  • Conduct simulated tests that show Triclosan may be present in humans, lake water, and soil.
  • Model how natural selection could result in the evolution of antimicrobial resistant bacteria.
  • Analyze readings to identify the benefits and potential risks associated with Triclosan.
  • Discuss actions that can be taken when the potential effects of chemicals are unknown or poorly understood.

MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.

  • Science & Engineering Practices

    Constructing Explanations - Construct an explanation that includes qualitative or quantitative relationships between variables that describe phenomena

  • Disciplinary Core Ideas

    LS4.B: Natural Selection - Natural selection leads to the predominance of certain traits in a population, and the suppression of others.

  • Crosscutting Concepts

    Cause and Effect - Phenomena may have more than one cause, and some cause and effect relationships in systems can only be described using probability
