The burning of fossil fuels negatively impacts the environment by contributing to the enhanced greenhouse effect and global warming. The document discusses how the greenhouse effect traps heat from the Earth's surface, which would otherwise be around -18 degrees Celsius without this effect. However, increased greenhouse gases from human activities like burning fossil fuels are enhancing this effect and causing average global temperatures to rise. This phenomenon is called global warming. The document instructs students to learn more about these topics by watching videos, completing an activity comparing past and present temperatures, and making posters explaining the process of global warming.

1. Entry Task
How does the burning
of fossil fuels
negatively impact the
environment?

2. LAST AoW!
Due Day 10 = Thursday, May 25th

3. Interactive Notebook:
Title = Greenhouse Effect & Global Warming

4. The Greenhouse Effect:
Video:

enhouseeffect/
Complete the video notes handout.
Share answers with the class after watching
the video!

6. The Greenhouse Effect:
When heat from the Earth is absorbed by
greenhouse gases in our atmosphere and then
emitted back to Earth, the Earth’s surface and
oceans heat up. This is known as the greenhouse
effect.

7. The Greenhouse Effect:
Without the greenhouse effect,
the Earth’s surface would be about
-18 degrees Celsius (or about -0.5
degree Fahrenheit) and most life
could not live.

8. The Enhanced Greenhouse Effect:
Is the increasing amount of greenhouse gases in
the atmosphere as a result of human activities.
Greenhouse Gas: gases in our atmosphere
which absorb heat energy from the Earth
and send it back to Earth; as a result, the
Earth becomes warmer.
e.g. carbon dioxide (CO2), methane (CH4)
 come from natural and artificial sources
Great Video Link!

9. What is global warming?
What do we already know about
global warming?
What does the Greenhouse Effect
have to do with Global Warming?

10. Global warming refers to the increase
in temperature around the world over
the last half of the twentieth century.
 Global Warming: is an increase in average
temperature of the Earth's surface and oceans from
1905-2005, the global average surface temperature
increased 0.74 degrees Celsius (or about 1.4 degrees
Fahrenheit) in some areas like Canada’s arctic, the
average temperature is rising more quickly (e.g. the
Mackenzie Basin has experienced an increase of 1.5
degrees Celsius or 2.5 degrees Fahrenheit)

11.  Global Warming Poster Activity
Split the class into groups of 4.
Hand out Global Warming Poster and review the vocabulary. Give
each group one A3 piece of paper.
Have the students create a creative poster that explains the
process of global warming. They need to include the words and
images on the sheet of paper.
Afterwards, have the students present their posters, and come
up with a class image of how global warming works. You can
have them write it in their notebooks as you draw it on the
board.
You can even watch the BrainPop on global warming at this point
if you want. It’s repetitive but the reinforcement is good.
