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!

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.
