Description:

This section aims to teach students how poor respiratory hygiene can lead to the spread of microbes and disease. Students observe how far microbes are carried when they sneeze and how many people can be affected.

Activities include:

  • Aerosol sneeze experiment where students observe how far microbes in a sneeze can spread and the best way to stop them.
  • Discussion activity considering what the best way to cover a sneeze is.
  • Use a flight plan to discuss how a strain of flu is spread around the world.
