Extension: carbon emission

Carbon is the gas created when we use energy. The more energy we use, the higher the levels of carbon is detected in our environment. We call this Carbon Emission. High levels of carbon can affect our weather patterns causing the earth to heat up at a faster rate. You may have heard this discussed when people talk about Global warming.

Carbon footprint explained

1

Your carbon footprint is a mark you leave on the environment.

2

Ask students to write down everything in their lives that consumes energy – such as getting to school, going to the movies, or buying a milkshake.

3

Discuss ways that they could replace some of the things on their list that use less energy.

4

Talk about ways that your school can reduce its carbon footprints, too. What could your school do to use less energy?
