What is global warming?
This PowerPoint presentation explains what our 5th grade students are investigating about global warming .
The World Wildlife Federation (nwf.org) created some of the slides in this PowerPoint!
How Global Warming Works
Fossil fuels (coal, oil, natural gas)
Carbon Dioxide (CO2)
The Sun’s energy passes through the car’s windshield.
This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
Example of the Greenhouse Effect
What is a Carbon Footprint?
A carbon footprint is the amount of space that is required to support the resource needs and waste of a person.
Carbon Footprint
Did You Know…People in the United
States have the largest carbon footprint on Earth?
A big carbon footprint means that a persontakes more than the Earth can renew. A big carbon footprint is bad for the planet!
Effects of Global WarmingIncreased Temperature
Habitat Damage and
Species Affected
Changes in Water Supply
Rising Sea Level

Simple Things To Do
Turn off your computer or the TV when you’re not using it.
Take shorter showers. Heating water uses energy.
Keep rooms cool by closing the blinds, shades, or curtains.
Turn off the lights when you leave a room.
Use compact fluorescent bulbs.

500 lbs. of coal
What’s the difference?
•1,430 lbs. CO2 pollution avoided
•$30 saved
Simple Things To Do
Dress lightly when it’s hot instead of turning up
the air conditioning. Or use a fan.
Dress warmly when it’s cold instead of turning up the heat.
Offer to help your parents keep the air filters on
your AC and furnace clean.
Walk short distances instead of asking for a ride in the car.
Plant a tree. Recycle.
