Scenario Cards -- Health Systems Literacy

All scenarios use fictional characters. Do not ask students to apply these to their own health.

The Body Alarm​

Discussion:

  • What is the body doing?
  • Is this a sign something is wrong, or something normal?
  • What system is activating?

Scenario: Casey stayed up until 1am to finish a video game level. The next day, Casey cannot focus in school, forgets a conversation from the morning, and is very irritable by afternoon.

The Health Claim Check​

Scenario: A post online says: "Scientists have proven that eating blueberries every day cures brain fog forever."
