A year of documented learning ( MY LAST POST......E V E R )

Hello everybody this is my last post. I have had a lot of fun this year, especially because we got to use technology more then ever, and i liked that. It was a refreshing change from past years. Well here is my final post.... what my favorite part off each section we learned was!

Astronomy or The study of the moon, stars, and other objects in space was one of my favorite sections mainly because i learned so much. One of the things i leaned so much about was the sun but more mainly how it causes the seasons on earth. The seasons are caused not by how close the sun is to the earth at different times(which i used to think) but by where the more direct sunlight is on the earth. Earth rotates on its axis, plus it is at a 45% angle so that means different parts of earth get more or less direct sunlight causing seasons.

My favorite part of the Weather and Climate book was the layers of the atmophere. I knew that earths atmosphere had layers i just didn't know what they were. They are : The troposphere ,the troposphere is the layer of the atmosphere in which Earth’s weather occurs. The stratosphere. The stratosphere is the second layer of the atmosphere and contains the ozone layer. The mesosphere, the mesosphere is the layer of the atmosphere that protects Earth’s surface from being hit by most meteoroid. And the thermosphere. The outermost layer of Earth’s atmosphere is the thermosphere.

Another one of my favorite sections was geology. More specifically plate tectonics or The theory that pieces of Earths lithosphere are in constant motion, driven by convection currents in the mantle. I thought this was really interesting because it explained why earth quakes happen. Earth quakes are just two of the plates rubbing up against each other. Also a volcano or a weak spot in the crust where molten material, or magma, comes to the surface is also explained by plate tectonics.

Weathering and Erosion was a very interesting topic. I especially liked the erosion part of it. More specifically wind erosion. Wind erosion has two parts; Deflation and Abrasion. Deflation is the process by which wind removes surface materials. When wind blows over the land, it picks up small particles of rock and sand . Abrasion is The grinding away of rock by other rock particles carried in water, ice, or wind. So it basically polishes rock away with other rock constantly hitting it.

OK finally, our latest book Earth's Waters. In earth waters we learned how water got to our houses from underground or in the air. From underground, i found out that water can come from aquifers or an underground layer of rock or sediment that holds water. There is also a artisan well or a well in which water rises because of pressure within the aquifer. We can also get our water from above ground in lakes our ponds. We even make reservoirs or A lake that stores water for human use. From these sources it goes to a pipe system to a treating plant here it gets treated This is the treatment process. We also learned the process how water goes in a cycle to precipitate and evaporate called the water cycle.

Well That was my final post it was a great year, with lots of fun and laughs. I sure will miss it. Well this is Larry, signing off F O R E V E R

This is a good song for the end of the year

Where coloardo springs's water comes from

Colorado spring's water comes fro a couple of different places. Through a system of pipes and facility's to get to us. The water states in areas of Aspen, Leadville and Breckenridge. In areas like homestead lake. That makes up 75% of our water. The other 25% comes from from local surface water sources and local ground water sources. These include

Local Surface Water Sources:

• Pikes Peak Northern and Southern Slopes
• Cheyenne Creeks
• Fountain Creek
• Peakview Reservoir in Monument
• Northfield Watershed

Local Ground Water Sources - Aquifers:

• Arapahoe (4 wells)
• Denver (1 well)
• Laramie-Fox Hills (1 well)
• Widefield (4 wells)

Water Cycle Activity

1.What is the water cycle?
1.A : A process that lets water move through the enviroment in a continus cylcle.

2.Does the water cycle have a beginning or end?
2.A: No becuze it is a cycle of evaporation condensation and precipatiation so it does not have a begining or end.

3.Starting with a puddle on a sunny day, describe how water might move through the water cycle and eventually fall back as rain.
3.A: The puddle is made out of water. When the suns heat heates it it changes state and evaporates. Then the water vapor rises and cools into water droplets and makes clouds. Then the water eventualy becomes heavey and falls out of the sky in the form of precipatation. The water then collects and the cycle begins again.

1b.The u.s doesn't us every much solar power compared to the rest of the world. Solar panels are made of silicone. silicone can hold an electrical charge well

2.http://www.howissolarenergyused.com/

2b.The sun is a main part of our life and becoming a bigger part.Solar panels use some different types of mechanics to turn the suns heat into electricity.

3.http://www.wisegeek.com/how-do-solar-panels-work.htm

3b. Solar panels are made of the same stuff as computers pure silicone. pure silicone can hold a charge better than other materials.

4b.Solar power has a big patently for being a main energy source.Solar power has Few limitations and is very reliable.It has barley any environmental impact.

Essential questions

1. What, specifically about your topic, are you going to research?
1.a I will research How the energy is harvested and how solar panels work.
2.What conclusions did you come to? What do you recommend average citizens do to make a difference?
2.b solar pannels are made out of pure silicone turned into small Cristal's mixed with other elements to create a positive and negative charge. A small amount of the worlds energy comes from solar energy. How we could make a difference is use these wonderful devises. They never stop working as long as there is sun light. First solar power is collected by solar pannels then sent to a charge controller then to a converter that changes it from dc to ac current. solar pannels are like magnifying glasses because they focus the energy.
3
What would happen if, worst-case scenario, nobody listened to your recommendations?
3b. The world would run out of coal to make electricity and we would not have electricity topower our earth and we would go back to medieva way of life.
4What would happen if, best-case scenario, everybody listened to your recommendations
4b. we would always have a renewable sorce of energy because if the sun goes out we would die any way.
