1. DO NOW:  STOP talking when the bell rings  Copy your homework in your planner  Open your science notebook to Ch6-2  Get out your grade log  Pick up the green study guide and blue ½ lab sheet in the back  Who’s presentation is this??

2. Convection Currents Lab Common mistakes

3.  Background Information:  1. did NOT describe 3 types of heat transfer  2. Give good examples  Hypothesis: did not do OR did not set up correctly “IF we heat up the oil, then the oil (fluid) will begin to move (convection current) “IF we heat up the oil, then the oil (fluid) will begin to move (convection current)  4. Did not draw and describe  7. Density decreased  8. Density increased at top of beaker

4. Do NOW:  Copy your homework in your planner Tape your foldable in your notebook  Open your spiral to your Convection Currents lab questions  Pick up your new lab sheet Phase Changes (back table)  Put your study guide out on your desk

5. Convection Currents Lab Reviewing conclusion questions:

6. Hypothesis: “IF we heat up the oil, then the oil (fluid) will begin to move (convection current)  4. Did you draw and describe  5. so we can see the particles move  6. heat was added, particles spread out and moved upward  7. Density decreased  8. Density increased at top of beaker  9. weather: air masses are heated / cooled  10. sun  CH: convection currents also cause the uneven heating of air masses=wind

7. Review of Ch 2-1 Phases  SOLID LIQUID GASES  Write down what you already know about each phase  Different color pen ADD notes as you read pages 34-38
