Introduction

In modules 2 and 3, students learned about the parts of the brain and how information is sent throughout the body. This module focuses on drugs - powerful substances that can change both the way the brain functions and how the brain communicates with the body. Some drugs are helpful when used properly: they fall into the category of medicines. Other drugs may have a harmful effect on the body. The purpose of today’s activity is for students to begin to understand how different drugs can affect the body.
