Science 10-3: Behind the Bottle - What's in the Bottle?
Objective: To illustrate the energetic cost of drinking bottled water.
Introduction: To get to the NWT a bottle of water must often travel thousands of kilometers. Besides the energy required for this transport, other energy is expended to create and store these bottles. As tap water quality is strictly monitored in the NWT this energy may not be of best use. The goal of this lesson is to generate awareness amongst students about the true energetic costs of bottled water.
Curriculum Connections: Unit B – 1: existence of energy in a variety of forms; select and integrate information from various print and electronic sources or from several parts of the same source Unit D - 4: assess risks and benefits of human activity
