How can you explain protecting the earths ozone to a first grader?

here is your answer
It turns out that certain types of molecules can cause a chemical reaction when they come in contact with ozone molecules. This causes the ozone to break up and become unable to absorb ultraviolet light. The main molecules that are destroying the ozone layer are called chlorofluorocarbons or CFCs.
Old refrigerators - If you have a refrigerator made before 1995 it probably uses refrigerant made from CFCs. Get a new refrigerator and be sure to have the old one disposed of properly.
Air conditioning - Old air conditioners, made before 1994, typically used a CFC called Freon.
If you still have one of these, it's time to get rid of it and buy a new one. Even newer air conditioners use chemicals called HCFCs. Even though HCFCs are better for the ozone, they still contribute to the depletion, so try and use as little air conditioning as possible.
Foam - A lot of foam products contain CFCs. Try and use different packing materials such as crumpled old newspapers.
Facts About the Ozone LayerThe word "ozone" means smelly in Greek because the gas has a strong odor.CFC molecules are highly stable and can last for up to 100 years. Unfortunately, this gives them plenty of time to find their way to the ozone layer.One chlorine molecule from a CFC can destroy up to 100,000 ozone molecules.Ultraviolet rays can also have bad effects on nature. They can kill plankton, which is a major source of food in the ocean's food chain.The ozone layer over Antarctica is very thin. It is sometimes called the "hole" in the ozone layer.

There are many simple ways to save our ozone layer.
Avoid the purchase and use of aerosol sprays containing chlorofluorocarbons (CFCs).
Avoid the use of fire extinguishers with halogenated hidrocarbon, a substance being very aggressive to the ozone layer.
Avoid buying insulating material made from CFC.
