Earth Day Science

Earth Day is just around the corner. Now is the perfect time to teach children about respecting and caring for the earth. Earth Day science is a great way to give hands-on lessons about recycling, renewable energy and the environment. Here are some fun facts we’ve assembled.

• The first Earth Day was on April 22, 1970. Gaylord Nelson, a U.S. Senator from Wisconsin began the day to organize a large public demonstration to get the attention of politicians. The first Earth Day was celebrated by more than 20 million people. Earth Day is credited with starting the modern environmental movement.
• Recycling one ton of paper saves an average of 7,000 gallons of water, 3.3 cubic yards of landfill space, 3 barrels of oil, 17 trees and 4,000 kilowatt-hours of electricity (enough to power the average home for 6 months).
• What is a “green” product? Green products are safe for the environment, contain no chlorofluorocarbons (they destroy the ozone), they decompose and are made from recycled materials.
• What do the recycle numbers mean on plastic?
  Plastic #1 – polyethylene terephtalate (PETE or PET). Disposable water bottles are made from the clear plastic

The Incredible, Edible Exploding Egg

Do not try this at home. Instead, watch your chemistry teacher perform this demonstration.

If you know me, you know I don’t do things the easy way. I do things the explosive way. If there is a flame involved, I’m all over it. So I decided to make use of all of the left over Easter eggs this week and crack them with a little fire.

You may not need safety helmets, matches and a little gas to crack an egg, but that’s the way I roll.

First, I poked a hole on each end and blew out the inside. Then I filled the empty egg with a little hydrogen gas and lit it on fire. When the hydrogen burns, oxygen comes into the egg and mixes. When the hydrogen and oxygen mix, you get water while a little energy is released. The energy blows the egg up.
