2. Introduction We are going to take a journey around the troposphere and learn about the weather. We will be going through the water cycle, clouds, and storms.

3. Troposhere On our first stop we are going to learn about the troposphere. You will be able to view streamline videos and brain pop videos. You will also follow links to deepen your discovery of the troposphere layer. Be sure to follow all directions given to you.

4. Troposphere The layer of the atmosphere nearest the earth’s surface. This is where all the weather on earth occurs. It is also where we live. It is the lowest layer in the atmosphere. It contains 85% of the earth’s air. http://www.brainpop.com/science/earthsystem/earthsatmosphere/ http://meteorologyclimatology.suite101.com/article.cfm/the_troposphere

5. Water Cycle About 70% if the earth’s surface is covered by water. Earth is referred to as the water planet. Not all of the earth’s water is in the oceans. http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Watercycle.shtml http://www.brainpop.com/science/earthsystem/watercycle/ http://www.kidzone.ws/water/

6. Process of the Water Cycle Evaporation Condensation Precipitation Saturation Surface Run-off

7. Evaporation Evaporation is the process by which a liquid changes into a gas. http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/evap.rxml

8. Condensation Condensation: is the process by which a gas, such as water vapor, changes into a liquid. Condensation occurs when moist air cools. http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/hyd/cond/home.rxml

9. Precipitation Precipitation: Any type of liquid or solid water that falls to the Earth’s surface. http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/prcp/home.rxml

10. Surface Run-off http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/prcp/home.rxml Water runs off into bodies of water, or soaks into the ground as groundwater.

11. Clouds Our third stop is going to be clouds. We are going to learn how clouds are formed, the types and what kind of weather they bring. We will using various websites, streamline videos, and brain pop. http://player.discoveryeducation.com/index.cfm?guidAssetId=A67F6299-8E81- 4136-97A5-582DBCE98CD8&blnFromSearch=1&productcode=US Click on the link below, and watch The Types of Clouds clip.

12. How Clouds are Formed Clouds are made of condensed water vapor. As warm air rises in the atmosphere, it cools. When the air cools to its dew point, the temperature http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/clouds/cloud_for mation.html&edu=elem

13. Types of Clouds Cumulus Cirrus Stratus Cumulonimbus Nimbostratus http://www.brainpop.com/science/weather/clouds/

14. Clouds Cumulus-Puffy clouds that look like cotton balls Cirrus- Thin wispy clouds that bring fair weather. Stratus-low, layered clouds that cover the sky. Fog is an example. Nimbostratus-layered clouds that contain rain. Cumulonimbus- Large towering clouds that usually contain thunder, lightning, and rain. http://schoolscience.rice.edu/duker/weatypeclouds.html http://eo.ucar.edu/webweather/cloud3.html

15. Thunderstorms A thunderstorm is a storm with lightning and thunder. They get their energy from humid air. When warm, humid air near the ground moves up vertically into cooler air above, the rising air, or updraft, can build a thunderstorm quickly. http://www.weatherwizkids.com/weather-thunderstorms.htm
