1 What is the composition of the air that we breathe? ES 2a

2 What are the gas molecules in our air?

3 Molecule in Air # of moleculesPercent of molecules

4 What gas is the main component of our atmosphere?

5 What is the correct order of the layers of our atmosphere? ES 2a

6 In what layer of the atmosphere does weather develop? ES 2a

12 In which layer of the atmosphere do you live?

13 In which layer of the Atmosphere do storms occur?

14 What layer of the atmosphere does ozone filter out UV light from the sun? ES 2a

15 Ozone?! Whats that? p. 441 Chimpanzee Book p. 53 Small Text book

16 Ozone?! Whats that? Where is it? Why is it important? Is it helpful? Is it dangerous? How does it affect me? What is it? p. 441 Chimpanzee Book p. 53 Small Text book

17 Where is Good Ozone and Why is it Good?

18 How does temperature change as you increase in altitude?

19 What does space feel like?

20

21 How does Pressure affect Temperature ?

22 Before After

23 How would YOU measure How Temperature changes with Altitude? AltimeterBalloonThermometer

24 How would YOU measure How Temperature changes with Altitude?

27

28 How does Temperature change as you travel upwards and Why?

29 What is the difference between climate and weather? ES 2a

30 Weather vs. Climate Periodic drought Warm summers Hurricane season Average precipitation Average Temperature Rainy season Humidity High winds ThunderstormAtmospheric pressure Hurricane Flash flood Cloudiness Freezing rain Tornado Snow

31 Weather vs. Climate Warm Summer Hurricane season Average precipitation Arid summers Periodic drought temperature, humidity, precipitation, cloudiness, brightness, visibility, wind, and atmospheric pressure, as in high and low pressure, sunshine, rain, cloud cover, winds, hail, snow, sleet, freezing rain, flooding, blizzards, ice storms, thunderstorms, steady rains from a cold front or warm front, excessive heat, heat waves, fog, flash floods, hurricanes, tornados, high winds Examples of Climate Examples of Weather

32 Weather vs. Climate Define Weather – Climate – Daily conditions (precipitation, temperature, pressure, etc…) The average weather conditions over 30+ years.

33 Describe the difference between climate and weather, and provide an example of each.

34 What are the different types of weather patterns found on earth? ES 2a

35 Wind Patterns What is Wind? What causes wind?

36 What is the difference between Sea Breeze & Land Breeze?

44 Describe one of Earths weather patterns.

45 If you were standing just North of the equator, what direction would the winds be blowing? ES 2a

46 How does a hurricane form? ES 2a

47 Hurricanes Whats the difference between a hurricane, cyclone, typhoon? How hot does the water need to be in order for a hurricane to start? What are the two main ingredients to make a hurricane? Relative to the equator, where do they always start? What else does a hurricane need to form? What does the inside of the storm look like? How are hurricanes related to tropical storms and depressions? What is a storm surge? And why is it so dangerous? Watch the short video…

48 What weather conditions form the perfect hurricane?

49 What patterns can you identify?

50 How does the Greenhouse Effect affect Global warming?

51 Greenhouse Effect Visit

52

53 Draw a diagram that demonstrates your knowledge of how greenhouse gases affect Earth.

54 How do Greenhouse gasses relate to Climate change?

55 Take the Climate Change Expedition For each of your 8 stops, record What you have Learned and your Passport Stamp Code. Agriculture Arctic Sea Ice Disease Droughts Ocean Temperature and Acidity Sea Level Snowpack Tropical Storms 1.Go to the link on our class website entitled Global Climate Changeclass websiteGlobal Climate Change 2.Select Learn the Basics 3.Take the Climate Change Expedition

56 Show your completed questions and Passport Stamps to Mr. Lee for credit

57 Greenhouse gasses & Global Climate Change List and Describe some of some causes of local climate change? How are greenhouses gases released into the atmosphere? What is the primary effect of greenhouse gases on the environment? …secondary? …tertiary? … Name some of the fossil fuels that we burn to create our energy.

58 Greenhouse gasses & Global Climate Change Name the more common greenhouse gasses in order of most abundant to least abundant. List some of the ways that methane is formed? How do we know that climate change has occurred in the past? And how can we predict its effects in the future? Describe how has the concentration of carbon dioxide on Earth has changed over time?

59 Sketch 2 globes and insert the Tropical, Temperate, and Polar regions to demonstrate your knowledge of Global Climate Change

60 Exploring AQI (Air Quality Index) Check out Dublins Air Quality rating for today on EPAs AirNow! website Which cities have the poorest air quality? …Why?!? Study Table 2 and Table 1 in chapter 36.2 from your Sustainability textbook Prepare your petri dishes to collect Particulates over the weekend. (Bring them back Monday to view under the microscope) Particulate linkParticulate link

61 What are the main causes of poor air quality?

62 Smog City 2 Play the simulation: SmogCity2.swf (in Safari) Answer the questions on your student handout Discussion: What interesting patterns did you learn?

63 What is the difference between primary and secondary pollutants?

64 Brainstorm: name as many air pollutants as you can think of.

65 Carbon monoxide Methane Particulates Sulfur oxides Nitrogen oxides VOC and Aerosols Ozone Sulfuric acid rain Nitrogen oxides

66 Brainstorm: name as many air pollutants as you can think of. Carbon monoxide Methane Particulates Sulfur oxides Nitrogen oxides VOC and Aerosols Ozone Sulfuric acid rain Nitrogen oxides Primary pollutantsSecondary pollutants

67 Check out the 4 short videos on Habitable Planet.org Habitable Planet Boundary Layer in Mexico City Killer London Fog Ozone: Good or Bad? Ozone… NO 2 … Ozone… NO 2 … Ozone!

68 Carbon monoxide

69 SO 2 (Sulfur oxides) What are the worst polluted sites in England?

70 Acid Rain!!

71 What do you think is the Point Source of SO 2 pollution?

72 With electricity, comes Sulfur Dioxide. Which states are the biggest culprits for SO 2 ?

73 What is happening to the SO 2 pollution over time?

74

75 NO 2 (Nitrogen oxides) Source: Courtesy Jim Gleason, USA and Pepijn Veefkind, KNMI, National Aeronautics and Space Administration.

76 Aerosols

77 Describe the difference between primary and secondary pollutants and provide and example of each.

78 Why is the Clean Air Act important to you? PI 2a

79 Visit the EPA Brainstorm 10 specific reasons why you should be concerned about your AQI Hint: See Activity 36.2 (you may also search on the web)

80 Brainstorm: What are some of the benefits from the Clean Air Act?

81 Describe 3 ways you are benefiting from the Clean Air Act
