Convection Lab PPT
- 1. Convection Lab EQ: Explain how energy from the sun causes clouds and sea breezes Standard: HCPS III 8.8.6 Forces that Shape the Earth Explain the relationship between density and convection currents in the ocean and atmosphere
- 2. What is convection? Convection: The movement of heat through the air.
- 5. Purpose of Experiment What is the movement of air when there are two different temperatures?
- 6. Materials 1.Plastic Bin 2.Metal Lid 3.Incense 4.Ice Pack 5.Candle 6.Tubing with Funnel
- 7. Procedure 1. Position the Candle in the plastic bin so it’s under the big hole of the metal lid. 2. Connect tubing to smaller hole. 3. Place ice pack next to the smaller hole. 4. Light the candle. 5. Place incense on foil and light it. 6. Put funnel over incense to send smoke into the bin.
- 8. Hypothesis If.. (independent variable) Then.. (dependent variable) Because.. (support with background info)
- 9. Discussion 1. In the evening, right after the sunsets, which direction will convection send the air? Explain. 2. How does convection lead to the formation of clouds?
Editor's Notes
- #2: Discuss with elbow partners
- #4: At the beginning of the day, which is warmer, the sand or the water? Explain why. (Use the terms differential heating and radiant energy.) In the evening, right after the sunsets, which direction will convection send the air? Explain.
- #5: At the beginning of the day, which is warmer, the sand or the water? Explain why. (Use the terms differential heating and radiant energy.) In the evening, right after the sunsets, which direction will convection send the air? Explain.
- #9: If there are two different air temperatures from the candle and the ice, Then the smoke will move counter-clock wise, rise above the candle, then fall below the ice, Because hot air rises and air moves from higher pressure to lower pressure.
