  1. Saving our Earth one house at a time! Insulation experiment

  2. Energy Quiz! ? • 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. ? ? ?

  3. “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!

  4. Greenhouse effect • Greenhouse gasses allow sun to enter the Earth. • Guess what! There is a lot more to the sun then just visible light!

  5. Where greenhouse gasses come from • Plant and animal respiration ( we exhale carbon dioxide) • Driving cars • Heating and cooling a living space • Drinking from plastic water bottles • Forest losses • Eating non – local foods

  6. Insulators • 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.
