What is global warming? This PowerPoint presentation explains what our 5 th 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 (CO 2 )
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 person takes more than the Earth can renew. A big carbon footprint is bad for the planet!
Effects of Global Warming Increased Temperature Habitat Damage and Species Affected Changes in Water Supply Rising Sea Level
What’s the proof that global warming is taking place?

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.
Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent 500 lbs. of coal What’s the difference? 1,430 lbs. CO 2 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.
