Pathogens, Antibodies, and Vaccines


Model how vaccines protect against bacterial diseases

How does the immune response protect against diseases caused by bacteria?

  • Create models of pathogens, antibodies, and antigen-antibody interaction.
  • Perform simulated laboratory tests to compare the antibody levels of unvaccinated and vaccinated children children who have been exposed to the bacteria that cause pertussis.
  • Learn about the importance of childhood vaccinations to prevent diphtheria, tetanus, and pertussis.

MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells

  • Science & Engineering Practices

    Developing and Using Models - Develop and use a model to describe a phenomenon.

  • Disciplinary Core Ideas

    LS1.A: Structure and Function - In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.

  • Crosscutting Concepts

    Structure and Function - Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem.
