  1. Heat Transfer Objective: SWBAT compare and contrast convection, conduction and radiation WARM UP: The warm up will be on the next slide Announcement: Atmosphere Vocab QUIZ NEXT CLASS

  2. Jack went swimming at the beach. When he got home, his towel was wet so he put it outside on a chair. An hour later, the towel was dry. Pick the answer that best describes what happened to the water that was in the towel an HOUR LATER: A. it soaked into the ground B. disappeared and no longer exists C. It’s in the air in an invisible form D. It chemically changed into a new substance E. It went up to the sun F. It broke down into atoms of hydrogen and oxygen

  3. Test 1: Measurement and Scientific Process Skills • “Bell curve” of grades seen- wide range of scores but most fell in the average range • Let’s go over the test • Do you have any questions? • Corrections opportunity • Tape your test in your notebook on the TEST DAY page

  4. Layers of Atmosphere HW • Any questions?

  5. Today’s Main Idea • How does our air get warm?

  6. DRAW the setup on the side counter HEAT! HEAT! HEAT!

  7. Transfer of Energy • Find the definitions of Convection, Conduction, and Radiation on your vocabulary sheet • What are they?

  8. Heat Transfer • Convection: Transfer of energy from place to place by motion of LIQUID or GAS

  9. Heat Transfer • Conduction: Transfer of heat energy from one substance to another through DIRECT CONTACT

  10. Heat Transfer • Radiation: energy that travels across distance in certain types of waves

  11. Back to your Drawing… • Using the definitions of energy transfer, LABEL your drawing to show where each occurs!

  12. CONDUCTION CONVECTION CONDUCTION HEAT! HEAT! HEAT! For radiation, hold your hand close to the top of the hot plate. What do you feel?

  13. What does this have to do with the atmosphere? • http://www.classzone.com/books/ml_science_share/vis_sim/eam05_pg19_conduct/eam05_pg19_conduct.html

  14. Diagram • Page A 18 in your textbook • Draw diagram • Label and write about Radiation, Conduction, and Convection

  15. Diagram to Draw- from textbook

  16. Tying This Week All Together… • Bill Nye “Atmosphere” video • DRQ done in notebook • Class work grade
