Putting alcohol to the test of science


This learning and evaluation situation is an opportunity for students to become aware of and adopt healthy habits, in the event that they ultimately decide to drink. They will use what they already know and gather the scientific information they need—about binge drinking, calculating blood alcohol content, what happens when you mix alcohol with energy drinks, etc.—to help the characters in this module agree on how to behave, should they find themselves in the presence of alcohol at parties.

While the situations illustrated here are fictional, they can be a useful starting point for conversations about the impact of alcohol on the human body, and about the living world and the material world, with a particular focus on the digestive, respiratory, circulatory, excretory and nervous systems.
