Drill Think back to our Solar Oven project. We talked about the three types of thermal energy transfer – conduction, convection, radiation – occurring inside the solar oven. 1. Describe how each process occurs. 2. What type of electromagnetic (EM) radiation entered the solar oven? What type of EM radiation warmed your food?

Drill – On a Whiteboard… 1. What do you know about global warming or climate change? 2. What questions do you have? What do you want to learn about in this unit?

Solar Oven – Earth Connections Thermal energy transfer = conduction, convection, radiation 1. Visible, UV light enter solar oven/Earth’s atmosphere. 2. Visible, UV light are absorbed by the black paper/Earth and converted into infrared (IR) radiation. 3. IR radiation is emitted from solar oven/Earth. 4. Some IR radiation escapes, some IR radiation is trapped by the saran wrap/atmospheric gases.

Infrared Radiation • Most sunlight is converted into IR radiation to heat Earth. • Light bulbs convert only 10% of electrical energy into visible light, 90% is converted to IR radiation. • Toasters, space heaters, hair dryers, curling irons, etc. use IR radiation to transmit thermal energy.

Is the Greenhouse Effect Beneficial or Detrimental to Earth? No greenhouse effect = Earth would be a frozen ball of ice = no life could survive. Too much greenhouse effect = Earth is warming to an extent that causes many problems.
