It's Getting Hot in Here

Greenhouse gasses trapped in the atmosphere are causing the planet to warm up over time. To see this in action, try an easy experiment at home. You will need a glass jar and 2 thermometers. Find a sunny spot outside to place your thermometers. Place one thermometer in the closed jar and one next to the jar. Come back in 30 minutes and see if there is a difference in temperature. Talk with a grown-up about what you noticed.
