Weather Notes: Air Pressure (1.2) Presentation Transcript

  • 1. RECAP WHAT WE KNOW Quickwrite: What is air? How does air affect us? Tuesday, February 10, 2009
  • 2. OBJECTIVES What is air? What are the properties of air? Tuesday, February 10, 2009
  • 3. DOES AIR HAVE MASS? Mr. Fox has no idea if air has mass? He is very embarrassed. Please help him by designing a quick experiment to test if air has mass. Brainstorm a couple of ideas and then try one out. Tuesday, February 10, 2009
  • 4. PROPERTIES OF AIR Density = Mass divided by Volume If a you 16 ml of a gas and it’s mas is 4g. What is it’s density? If you have 10ml of a gas with a density of 0.04 g/ml. How many grams of gas do you have? Tuesday, February 10, 2009
  • 5. UNDER PRESSURE Pressure: The force pushing on an area or surface Air pressure: comes from the heavy column of air pushing down The weight of the column of air above you is as heavy as a school bus!!! Why doesn’t it squash you? Tuesday, February 10, 2009
  • 6. DENSITY AND PRESSURE How do you think density and pressure are related? Tuesday, February 10, 2009
  • 7. MEASURING AIR PRESSURE Measured by a Barometer in millibars or inches of mercury. Sketch of barometer. Tuesday, February 10, 2009
  • 8. ALTITUDE Motivational Quote: Your attitude determines your altitude! Air pressure decreases as altitude increases. As air pressure decreases, so does density. Give an example of this phenomenon. Tuesday, February 10, 2009
  • 9. SKETCH Sketch Mount Everest showing a microscopic view of the air molecules at the base and a view at the top. Tuesday, February 10, 2009
  • 10. COOL AT HOME DEMO Magic Glass Tuesday, February 10, 2009
  • 11. HOMEWORK Questions: Page 14 #’s 1-3 Tuesday, February 10, 2009
