11. Air Pressure: “Mystery Matter” Stations Review! Ch. 15.1 Please take out your mystery matter data sheets and open up your IAN. Mark your notes 2/11

12. Let’s discuss each fact and how they relate to our stations! Balloon in a bottle Balloon in a bottle Balloon in a bottle Just a little more magic! Just a little more magic!

13. Station #1 How Does Air Motion Affect Objects? What changes did you observe as you watched the balloon? What might have caused the changes you observed? Draw what happened! Before:During:

14. BALLOON TYPEMASS (in grams) Empty Air-Filled Station #2 – Does Air Have Mass? Did you observe a change in mass? If so, why? (2 sentences)

15. Station #3 – Is Air There? 1. What happened when you tried to push the bag into the jar? 2. What happened when you tried to pull the bag out of the jar? 3.Analyze the results. Why do you think that you got the results that you did?

16. ACTIONOBSERVATIONS PRESSURE IS HIGHER…. (inside the heated balloon or inside the cooled balloon) Heated balloon with hot water Cooled balloon with ice water Station #4 – Shrinking or Expanding Air? Why do you think the pressure varied (was different) for each action? (2 sentences)

17. Station #5 – Does Air Take Up Space? Describe what happened to the cork. What happened to the water level inside the glass container as you pushed the container towards the bottom of the bowl? What happened to the water level outside the glass container as you pushed the container towards the bottom of the bowl? In summary, what caused the results that you observed to occur?

18. Station #6-“Pull it apart!” What happens when you try to pull the pressure pullers apart? What do you think is causing this? You are reducing the air pressure in between the cups. Result: a higher air pressure is on the outside This is what is pushing them together!

19. Air Pressure Review Air has mass. Air takes up space. Air has density. Air can move. Air pressure is the weight of a column of air pressing down on an area. Low and High Pressure want to be balanced!

20. Atmosphere/Pressure Atmosphere is held in place by gravity Air Pressure is strongest at surface-more air above you (You carry a column of air that is 700 km high on top of you every day! *as altitude increases, air pressure decreases –Stack of books –(Denver Broncos)

21. Bell Ringer: Let’s Review! Answer the following questions in your IAN. Why does air in the atmosphere have pressure? How does altitude affect air pressure? Name one thing found in the –Stratosphere –Mesosphere –Troposphere

22. Air Pressure As Air Pressure decreases, so does density.

24. Characteristics of Atmosphere Atmosphere: a mixture of gases that surrounds Earth: acts like a blanket Protects from sun’s damaging rays Contains mostly nitrogen78% & then oxygen21% –Also has solids and liquids, what are they? ( dust, water vapor, dirt, volcanic ash, smoke) You can see them at night when you turn on a flashlight!

25. The most abundant gas in the air we breathe?

26. Layers of the Atmosphere Troposphere-we live here, weather happens here. Densest layer b/c it has 90% of the atmosphere’s mass! Almost all of the Earth’s CO2, H2O Vapor, clouds, air pollution, and life-forms live here. Stratosphere: ozone layer- protects life by absorbing harmful UV rays. Gases are layered here, do not mix much. Very thin, little moisture.

28. Mesosphere: “middle layer”, coldest The ionosphere: Upper meso and lower thermo, absorbs harmful solar energy. (auroras exist here- SS connection!) Thermosphere: satellites, Although it has very high temps, it does not feel hot b/c it is less dense and air particles move fast- no transfer of thermal energy

30. Atmosphere

31. Review: Egg in a Bottle Fire warmed up air inside, molecules escaped before egg was put on top and then egg wobbled. When fire went out, temperature cooled, molecules condensed, changing air pressure. Since the pressure outside bottle was higher, the higher pressure tried to get in the bottle. Since the egg is squeezable, it got pushed into the bottle by the air.

32. TICKET OUT THE DOOR You are sitting on an airplane on the ground. The pilot announces take off and the plane begins to climb higher in the atmosphere. You notice that your head feels like it is getting clogged. Suddenly, you swallow and you hear a popping noise in your ear. Explain what happened.

33. In Summary: Let’s Review! Answer the following questions is your IAN. Why does air in the atmosphere have pressure? How does altitude affect air pressure? Name one thing found in the –Stratosphere –Mesosphere –Troposphere Atmosphere Brainpop Atmosphere BrainpopAtmosphere Brainpop
