1. Earth’s Atmosphere Why is it so important to life on earth? S6E4 Students will understand how the distribution of land and ocean affects climate and weather

2. Today at a Glance 2-22-16 S6e5d Minerals, Rocks, Fossils, & S6e4 SW understand the land and ocean’s affects on climate and weather Activity 1: We Do: Bell work Determine if the statement is true or false. Cite evidence.  Moving water can be used to produce electricity.  Water wheels were once used to power cars.  Hydroelectric dams can cause many ecological problems.  Hydroelectric energy is non-renewable. Activity 2 mini lesson I DO/You DO Review for test. Activity 3: I Do/ You Do: Earth’s atmosphere notes Pictionary or jeopardy.

3. Earth’s atmosphere is made up of 5 different layers…

4. Did you know that The Science Monkey’s Took Evan? The Science Monkey’s Took Evan Say it with me…

5. I know you are thinking…what is she talking about??? The The Science Science Monkey’s Monkey’s Took Took Evan Evan MEANS…. MEANS…. Troposphere Stratosphere Mesosphere Thermosphere Exosphere THE FIVE LAYERS OF THE EARTH’S ATMOSPHERE FROM THE EARTH OUT!

6. Why is the atmosphere divided into 5 different layers? Any guesses? The atmosphere is divided into five different layers because the atmosphere is not uniform, its properties change with altitude. The atmosphere is divided into five different layers because the atmosphere is not uniform, its properties change with altitude. Two properties change with altitude, the AIR PRESSURE and the AIR TEMPERATURE Two properties change with altitude, the AIR PRESSURE and the AIR TEMPERATURE Lets look at each layer individually. Lets look at each layer individually.

7. The first layer of the atmosphere is the… The troposphere is the layer of the atmosphere nearest to earth. The troposphere goes from 0km to 16km. All weather happens in the troposphere. More than half the air in the total atmosphere is in this layer. The temperature drops as the altitude increases. Harmful ozone is found here…IT CREATES SMOG! TROPOSPHERE

8. What is OZONE? A gaseous layer in the upper atmosphere that protects the earth from harmful ultraviolet radiation. At lower levels, ozone becomes a major pollutant. What is SMOG? Pollution formed by the interaction of pollutants and sunlight (photochemical smog), usually restricting visibility, and occasionally hazardous to health.

9. The second layer of the atmosphere is the… The stratosphere goes from 16km to 50 km. The stratosphere goes from 16km to 50 km. The temperature goes up with altitude. The temperature goes up with altitude. Most jets fly in this layer. Most jets fly in this layer. The protective ozone is at the top of the atmosphere (It protects us from the ultraviolet radiation of the sun.) The protective ozone is at the top of the atmosphere (It protects us from the ultraviolet radiation of the sun.) Rivers of air, called Jet Streams, can be found at the base of this layer. Rivers of air, called Jet Streams, can be found at the base of this layer. STRATOSPHERE

10. The third layer of the atmosphere is the… The Mesosphere goes from 50km to 90km. In the mesosphere, the temperature drops with altitude. The mesosphere is the coldest layer of the atmosphere. Meteors burn up in this layer. Radio waves are reflected back to earth in the mesosphere. MESOSPHERE

11. The fourth layer of the atmosphere is the… The thermosphere goes from 90km to 300km. The thermosphere goes from 90km to 300km. In the thermosphere the temperature goes up with altitude. In the thermosphere the temperature goes up with altitude. The thermosphere is the hottest layer of the atmosphere. The thermosphere is the hottest layer of the atmosphere. Curtains of light called auroras occur in this layer. Curtains of light called auroras occur in this layer. The Ionosphere is found in the thermosphere. This is the component of the thermosphere that makes the auroras. The Ionosphere is found in the thermosphere. This is the component of the thermosphere that makes the auroras. THERMOSPHERE

12. The last layer of the atmosphere is the… The exosphere is the outermost layer of the atmosphere. The temperature in the exosphere goes up with altitude. Satellites orbit earth in the exosphere. EXOSPHERE

13. GOOD LUCK! It is important to understand the different characteristics of the earth’s atmosphere. As you go through the following slides, challenge your partner to see who can name the correct layer in which each characteristic can be found.

14. Today at a Glance 3-2-16 S6E4 Students will understand how the distribution of land and ocean affects climate and weather Activity 1: Bell Work We Do 1. Why do you think rain and clouds occur mostly in troposphere? 2. Where is air pressure greater? 3. Define the term ionosphere. Activity 2: you will work in groups of 3 to create a skit about how the depletion of the ozone layer might affect different organisms. Wait for directions. You will have 15 min only

15. Today at a Glance 3-2-16 S6E4 Students will understand how the distribution of land and ocean affects climate and weather Activity 2 continue You Do 1. Your organism must be found on earth 2. Your organism must discuss the changes they are experiencing and their concerns for the future. 3. You will present the skit to the class 4. Remember there is only 15 minutes for this assignment.

16. Today at a Glance 3-3-16 S6E4 Students will understand how the distribution of land and ocean affects climate and weather Activity 1: Bell Work We Do  The thin layer of air that surrounds the earth is called_________.  How does driving a car affect the composition of the atmosphere? Activity 2: Mini Lesson You Do: Brain Pop Weather video. Student will complete the quiz following this lesson Activity 3: I Do/ you Do Finalize yesterday’s assignment and atmosphere notes.

17. Today at a Glance 3-4-16 S6E4 Students will understand how the distribution of land and ocean affects climate and weather Activity 1: Bell work We Do  The ozone layer helps protect us from _______.  Why does air pressure decreases with an increase in altitude. Activity 2: Georgia science textbook page 484. You will complete the anticipation guide on a separate sheet of paper to be turned in at the end of class. Our class discussion will begin with this activity.
