I can show where greenhouse

gases are found.

I will be able to explain what a

greenhouse gas is.

Gardens

Does anyone have a garden
where they can get fresh food

all summer?
Give me a ✅.

If you don’t, have you gone to

a farmers market?

Give me a 👍.

Fresh vegetables in

the winter

You don’t have to give up fresh

vegetables in the winter!

How can vegetables grow when

there is snow outside?

Why do you think the top is open

even though it is cold outside?

A greenhouse traps the sun's heat
and keeps plants warmer than
they would be without the
greenhouse. Greenhouse gases
do the same thing for the earth.

What is the Greenhouse Gases?

Carbon Dioxide Rise in the Atmosphere

So if the amount of greenhouse

gases keeps increasing in our
atmosphere then what could

happen?

Where is the ozone

found?

What do greenhouse gases do in our atmosphere?

🐢 They absorb radiation given off by the Earth

🐇 The keep all the air within the Earth

😀 They block harmful radiation from reaching the Earth

🔊 They make the Earth cooler

What do you
see around
our earth?

What is it
made of?

Our Atmosphere

Our atmosphere is a layer
of gases around the earth
that allows us to live on
the surface of the earth.

It is about 300 miles thick
but most of it is within 10
miles of the surface.

What is it?

The greenhouse effect is a
natural process that
warms the Earth's
surface. When the Sun's
energy reaches the
Earth's atmosphere, some
of it is reflected back to
space and the rest is
absorbed and re-radiated
by greenhouse gases.

What are greenhouse gases?

Greenhouse gases are gases in Earth’s
atmosphere that trap heat. They let sunlight
pass through the atmosphere, but they
prevent the heat that the sunlight brings from
leaving the atmosphere. The main
greenhouse gases are:

●Water vapor

●Carbon dioxide

●Methane

●Ozone

●Nitrous oxide

●Chlorofluorocarbons

Which of these have you heard of?

Did you know all of these were greenhouse
gasses?

Are greenhouse gasses always bad?

When people are talking about greenhouse gas
emissions, it is easy to think that there weren’t any
before the industrial revolution. Greenhouse gases at
normal concentrations are completely natural and
harmless. In fact, our planet needs them and life on this
Earth would be completely different if there was no
greenhouse gases in the atmosphere. In fact, scientists
are estimating that the average temperature on Earth
would be around -18 degrees Celsius. Greenhouse
gases are a natural part of the atmosphere, which
absorbs and emits thermal radiation, keeping
temperatures on Earth more or less the same.

Greenhouse gases have increased
since the industrial revolution. It has

impacted the temperature of the

earth.

What do you notice about these two

graphs.

Too many greenhouse gases

What’s the
highest
percentage of air
that could be
greenhouse gas?

Do you think we
need a big
change to make
a difference?

Which of the following is an example of a
greenhouse gas?

🐢 Oxygen

🐇 Nitrogen

😀 Water vapor

🔊 Neon

Lesson Summary

➢The atmosphere has 5 layers. We live in the
troposphere and the stratosphere contains the
ozone layer where greenhouse gases are.

➢We need greenhouse gases in order for the
earth to be warm enough for us to live on.

➢Too many greenhouse gases are like an extra
blanket on the earth and it makes it too hot.

➢A very, very small percentage of the
atmosphere is made of greenhouse gases.

Human Impact

Human Impact Fossil Fuels

We use fossil fuels for a lot of

different things. We use them to

power our cars, airplanes, and
lawn mowers. We also use them

to produce electricity.

When we burn fossil fuels all of

the stored carbon is released into

the air. This causes the
atmosphere to warm up.
