School project on Global Warming for a 5th Grader!!

2. What is Global Warming??
A gradual increase in the overall
temperature of the earth's atmosphere
generally attributed to the greenhouse
effect caused by increased levels of
carbon dioxide, CFCs, and other
pollutants.
Global warming is when the earth heats
up (the temperature rises). It happens
when greenhouse gases (carbon dioxide,
water vapor, nitrous oxide, and methane)
trap heat and light from the sun in the
earth’s atmosphere, which increases the
temperature. This hurts many people,
animals, and plants. Many cannot take
the change, so they die.

3. What is the Green House
Effect??
The greenhouse effect is when the temperature rises because the sun’s
heat and light is trapped in the earth’s atmosphere. This is like when heat is
trapped in a car. On a very hot day, the car gets hotter when it is out in the
parking lot. This is because the heat and light from the sun can get into the
car, by going through the windows, but it can’t get back out. This is what
the greenhouse effect does to the earth. The heat and light can get through
the atmosphere, but it can’t get out. As a result, the temperature rises.

4. What are the causes of Global
Warming??
• Natural Causes
–
Natural causes are causes created by nature. One
natural cause is a release of methane gas from
arctic tundra and wetlands. Methane is a
greenhouse gas.
• Pollution
–
In most cases, fossil fuels are burned to create
energy and electricity. Many pollutants (chemicals
that pollute the air, water, and land) are sent into
the air when fossil fuels are burned. Some of
these chemicals are called greenhouse gasses.
• Cutting Down of trees –
Trees and other plants collect carbon dioxide
(CO2), which is a greenhouse gas. This
gas, CO2, collects light and heat (radiant
energy), produced by the sun, and this makes the
earth warmer.

5. Some Facts about Global
Warming!!
•
There is more carbon dioxide in the
atmosphere today than at any point in the last
800,000 years
•
In the last century, sea levels rose roughly 7
inches after not having changed noticeably in
the previous 2,000 years. Sea levels rising are
an effect of global warming and put many
states at risk of existing in the near future.
•
Consequences of global warming include
drought, severe hurricanes, massive fires, and
melting of the polar caps.
•
Global warming puts coral reefs in danger as
warmer water increases the possibility of coral
diseases and the rising sea levels makes it more
difficult for coral to receive adequate sunlight..

Plant trees
Reduce, Reuse, Recycle
Switch every light in your house to an energy-saving bulb
Wear a sweater instead of turning up the heat in your house
Wear lighter clothing when it’s hot instead of turning on a fan
Turn lights electrical appliances when not in use
Take shorter showers
Skip the car ride and use your bike, or walk or take the bus
Don’t buy bottled water; drink tap water, and filter it if you like
Eat lower on the food chain (less meat) and eat fewer processed foods
Use Less Heat and Air Conditioning
Buy Energy-Efficient Products
Encourage Others to Conserve
