The Energy Trail
Description

This lesson helps students discover the links between consumer products, manufacturing and energy use, the burning of fossil fuels and the carbon dioxide emissions that contribute to climate change. Students learn by tracing the steps that produce the plastic components of a computer – from oil in the ground to the finished product being used at home.

Learning Objectives
To help students understand that the energy used in extraction, manufacture and transportation of material and products produces carbon dioxide emissions that are changing our climate.
Instructions for Students
o The whole class will discuss fossil fuels: what they are, how they are used to make many everyday objects and how they relate to carbon dioxide and climate change.
o The whole class will create a diagram that shows the steps needed to produce a computer. They will help to identify the stages in the manufacturing, packaging and shipping processes that require energy and result in CO2 emissions.
o Groups of students will select products and trace the energy that goes into their manufacture and distribution.
o The class will compare the energy used to produce various products we purchase and use.
o Each student will write a story, either about an object’s energy journey, or about their reflections on this lesson
