Insulation experiment
Saving our Earth one house at a time!
The process of heating and cooling account for 50 to 70 % of the energy used in the average American home.
It is predicted that the average temperature will rise another 3 to 10 degrees F in the next 100 years.
Energy Quiz!?

“Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace”
Global warming – the gradual temperature change in the Earth’s atmosphere due to primarily carbon dioxide build up from burning coal, oil and gas.
These are Greenhouse gases!
Greenhouse gasses allow sun to enter the Earth.
Guess what! There is a lot more to the sun then just visible light!
Greenhouse effect
Plant and animal respiration ( we exhale carbon dioxide)
Driving carsHeating and cooling a living spaceDrinking from plastic water bottlesForest losses Eating non – local foods
Where greenhouse gasses come from
An insulator does not allow flow of electrons.Insulation is a material or substance that is
used to prevent the transfer of heat, electricity or sound. In a building, insulation is placed in the walls and roof. When insulating a building, the quality of an insulation material is measured by how well it keeps heat out.
