2 Quiz/Test Procedure 1. Clear your desk of everything except a pencil 2. Noise level 0 3. Keep eyes on your own quiz/test at all times 4. Raise your hand to ask a question 5. Flip your quiz over and put your head down when you re finished Correcting Quizzes! 1. Use a pen or highlighter to correct quizzes 2. Sign your name at the bottom 3. Mark incorrect answers with an X and correct answers with a 4. Put a total score at the top + Unit Project Dynamic Earth You will need to create a model of the dynamic earth this can be a 3D model or a detailed drawing. You will also need to include a written paragraph/ report for each section of the dynamic earth: geosphere, atmosphere, hydrosphere, and biosphere Read over the rubric, and then decide what kind of model you would like to make Unit Project Dynamic Earth Note this project is worth 100 test points If you receive a 70% or higher on your project, you will not be required to complete the Ch. 3 Test. If you fail to turn in the project, you will be required to complete the Ch. 3 test 2&

3 Environmental Science Thursday, September 10, 2015 Do-Now: Brainstorm Week 4 Title your paper Brainstorm Week 4 1. Write down today s FLT 2. List the layers of earth, in order. 3. Which layer makes up most of Earth s mass? 4. What is the relationship between tectonic plates and where earthquakes occur? (Hint: read p. 63 if you forgot) Announcements& Recall:(( Project(is(worth(100(test(points(( You(must(complete(a(Ch.(3(test(if(your(project(is( missing/incomplete(or(you(receive(less(than(70%( Progress(Reports(due(9/21( Make(up(assignments/quizzes(by(9/14( Iceland(RegistraFon(( Register(by(9/17( Finish project!

4 Brainstorm Protocol Goal: generate the longest list possible Quantity > Quality Take turns clockwise ONE answer per person, and NO skipping You can help your classmate think of an answer, but you cannot tell them an answer Everyone must have the SAME EXACT list Pencils/Pens MUST be down when time is up Brainstorm Protocol Identify the person in your group with the most siblings This person will be starting Number your paper underneath your donow Brainstorm Protocol You will have one minute and thirty seconds to generate answers Group with the longest list = +5 dojo points each Your topic is. Brainstorm Protocol Tell me everything you know about Earth 1:29 1:28 1:27 1:26 1:25 1:24 1:23 1:22 1:21 1:20 1:19 1:18 1:17 1:16 1:15 1:14 1:13 1:12 1:11 1:10 1:09 1:08 1:07 1:06 1:05 1:04 1:03 1:02 1:01 1:00 0:59 0:58 0:57 0:56 0:55 0:54 0:53 0:52 0:51 0:50 0:49 0:48 0:47 0:46 0:45 0:44 0:43 0:42 0:41 0:40 0:39 0:38 0:37 0:36 0:35 0:34 0:33 0:32 0:31 0:30 0:29 0:28 0:27 0:26 0:25 0:24 0:23 0:22 0:21 0:20 0:19 0:18 0:17 0:16 0:15 0:14 0:13 0:12 0:11 0:10 0:09 0:08 0:07 0:06 0:05 0:04 0:03 0:02 0:01 End 1:30 4&

5 Brainstorm Protocol Count up your answers. Standard HS-ESS2-1: Develop a model to illustrate how Earth s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features FLT I will be able to describe the composition of Earth s atmosphere by completing Atmosphere Notes Notes: Noise level 0 Copy down all bolded ideas Raise your hand to question/comment Be prepared to pair-share Recall: last time we talked about the geosphere 5&

6 9/10/15& Why do planes fly as much as 10 km above the ground? Composition of the Atmosphere Most commercial planes fly ~33,000 ft because the air is MUCH less dense. Thus, the planes experience less drag, require less fuel, and have less turbulence. What is the atmosphere? The atmosphere = contains all of the gases on Earth, arranged in layers Some of the air is oxygen, which we breathe, but there are also many other gases, dust particles, and even some water vapor mixed into the air. 6&

7 9/10/15& Atmosphere Gases in the Atmosphere Gases include nitrogen, oxygen, carbon dioxide, and more Gases are constantly cycled through the atmosphere and earth We remove oxygen when we breathe in, and we add carbon dioxide when we breathe out Volcanic eruptions add gases Plants add oxygen via photosynthesis 7&

8 Gases in the Atmosphere Nitrogen " most abundant gas in atmosphere Enters through volcanic eruptions and decaying plants/animals Oxygen Enters via plant production Gases in the Atmosphere Other argon, carbon dioxide, methane, water vapor, etc Layers of the Atmosphere 4 Main Layers (based on temperature changes) in the atmosphere: 1. Tropsphere 2. Mesosphere 3. Thermosphere 4. Stratosphere 8&

9 Troposphere Troposphere = Lowest layer As altitude increases, temperature decreases Most life and weather occurs here Dense layer Up to ~18km Stratosphere Stratosphere = 2 nd layer ~18-50km Ozone (O 3 ) layer protects us from UV radiation, but also causes the temperatures to rise as altitude increases Mesosphere Mesophere = 3 rd layer Extends up to ~80km above surface Coldest layer There are few molecules (inc ozone) to warm the air Carbon dioxide also absorb heat form other molecules Almost outer space Absorbs solar radiation, resulting in extremely high temperatures Measured above 2,000 degrees! However, it would not feel hot because the air is so thin and heat does not transfer well Thermosphere 9&

10 ~100 to 400 km Air is very thin here heat does not transfer easily Northern lights occur (aurora borealis) The International Space Station orbits in this layer Thermosphere Two Sublayers: 1. Ionosphere: presence of ions allow for radio wave communication 2. Exosphere: Atoms and molecules can escape into space here Thermosphere The Greenhouse Effect Greenhouse effect = Warming of Earth s surface/lower atmosphere due to gases in the atmosphere that absorb and reradiate infrared radiation trapping heat on Earth Without the greenhouse effect, Earth would be too cold for life to exist. 10&

11 The Greenhouse Effect Pair-Share-Respond 1. Define atmosphere 2. What are the layers of the atmosphere, from lowest to highest? 3. Which layer contains our ozone layer? 4. Which layer is the most dense? 5. Explain, briefly, what is meant by the term greenhouse effect. CW 1. Active Reading Finish all binder assignments 3. Work on project 11&
