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

2009-05-14T18:06:00.011-06:00

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

2009-04-30T08:44:00.002-06:00

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

2009-04-27T17:36:00.002-06:00

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.

Essential questions

2009-04-15T08:45:00.006-06:00

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.

Observing waters properties on a penny

2009-04-13T16:32:00.002-06:00

A couple days ago in science class we did an experiment observing waters properties by observing how much water could fit on a penny. We used a medicine droper, a penny, and water. My first prediction was 7 dropes. The actual number was 16. My second prediction was 17. This time i went slow and i got a total of 28! What makes makes so muchg water be able to fit on such a small area is water has a high surface tension. That means water will stick together stronger then other liquids. Overall this was a fun experement.

Greenlands ice caps

2009-03-30T08:50:00.005-06:00

Greenland's ice caps found
off the coast of Greenland.

April 13, 2009
When i went to the ice caps off the coast of green land i went to see what i could do as an engineer to try to stop the ice from melting and causing the ocean water level to rise. When i got there it was beautiful but saddening at the same time. There were birds sitting all over the ice and cawing. I even saw a very large whale.When i took some measurements and compared them to my last ones, i realized the ice caps had shrunk and caused the worlds waters to rise. The locals know what is going on. Here in Greenland the locals use the water here for transportation and food. I a going back home now. Hope fully i can find a way to stop these huge glaciers from melting.

Earthquakes webquest

2009-01-23T08:00:00.001-07:00

1. Where do most of the earthquakes tend to happen? Answer this in two parts:

Part A: Geologically: Ware the plates rub against each other

Part B: Geographically: Western America and Alaska

2.I think that earthquakes tend to happen in this are is because that is ware the plates touch each other

3. This area is called the ring of fire

4 3 magnitude
Date-Time Thursday, January 15, 2009 at 12:10:02 PM
Location 40.953°N, 106.930°W
Depth 5 km (3.1 miles) set by location program
between:Large Quarry or Mine Blast
Small Nuclear Weapon
A magnitude 1 has 30 pounds of force a 3 magnitude has about 50 tons of force. So there is a huge difference in the feeling of the two.

5.My earth quake:
Magnitude 5.1
Monday, January 19, 2009 at 23:50:47 UTC
Baja California Sur, Mexico
There was some shaking but no one was seriously injured
6. Ways people can stay safe is to get in a sturdy house basement or shelter.

Weather fronts

2008-12-05T12:20:00.002-07:00

weather fronts include:
Cold Front
Warm Front
Stationary Front
Occluded Front

Cold front: A cold front happens when a fast moving cold air mass runs into a slow warm air mass. Then the warm air rises above the cold air. As it rises it cools causing clouds to form. Then if there was any water in it it would precipitate. And since strong wind is usually accompanied with cold air masses then you have a storm.

Warm front:A warm front happens when a fast moving warm air mass runs into a slow cold air mass. Then the warm air rises above the cold air. As it rises it cools causing clouds to form just like in a cold front. And since strong wind is usually accompanied with cold air masses then you have a storm.

Stationary Front : A stationary front happens when two slow moving cold and warm air masses meet and neither has the force to push the other. This can cause storms for days at a time.

Occluded Front: A Occluded Front is the most complicated fronts. It happens when a warm air mass is stuck in between two cold air masses. The warm air is pushed of the ground causing cold weather and snow.

Acid rain

2008-11-04T12:33:00.000-07:00

Acid rain is made when coal with lots of sulfur oxide is burned. Then the sulfur oxide goes into the air and mixes with nitrogen oxide and water vapor to create acid rain! The issue is that the acid rain can damage statues and buildings and make ponds and lakes uninhabitable. It can also kill trees. What we can do is burn less fossil fuels and use Eco-friendly fuel sources!

Earths atmosphere

2008-10-29T12:09:00.000-06:00

Earth is very special compared to other planets because of its atmosphere. Earths atmosphere is compromised of several different layers covering the earth in a protective blanket. One of these layers is the ozone layer. The ozone layer protects the people and animals of earth from harmful ultraviolet light produced by the sun. The earths atmospheric pressure witch creates high and low pressure systems. This allows for weather and thus less extreme temperatures like on other planets. The other substances in the atmosphere consist of 78% nitrogen, 21% oxygen, and 1% other gases.

The science of rockets - NASA uses a rocket system called "atlas" that has three stages. These stages are called "atlas", "centaur" ant the last stage in witch centaur burns up.

The space program- The Nation Aeronautics and Space Administration (NASA) was begun in 1958. It has had several missions including Apollo 13.

Exploring space today- The international space station is part of exploring space today. to help the people on it NASA have built a robot called "personal satellite assistant".

Using space science science on earth- The NASA program is very good for the economy. Yet they only get 1% of the united states budget money.

reasons for the seansons

object width="425" height="344">

Earth seasons are caused because of earths tilt on its axis and it position to the sun. When the earth is at a certain point in its orbit its tilted a certain way. That certain tilt makes it so more or less direct sunlight hits the earth. When more direct sunlight hits the earths northern hemisphere it is summer in the northern hemisphere. When more direct sunlight hits the southern hemisphere the southern hemisphere gets summer. That is the reason for earths seasons!

Zoom by Istvan Banyai was a very interesting book. It started as a very close up view of a roosters crown but eventually zoomed into space. I thought for sure the first picture was a dinosaurs foot. It taught me that even though you may think something is one thing it turns out to be another. That is basically what perspective is all about.
An example of perspective : one day my friend hit me in the face. I immediately thought he did it to be mean. After asking why he hit me he told me there was a fly. That one little detail widened my perspective. Perspectives can change just like that.
In the field of science perspective is not just a term it can also be different studies. Astronomers use far away perspectives. While doctors may need a microscope to see what there studying. As astronomers we need perspective to even imagine just one solar system let alone the galaxy. In astronomy perspective is huge.

The enigma box

2008-08-29T12:27:00.000-06:00

The five skills of a good scientist are important. I had to use 4 of the five skills were important to this observation.I had to use my senses i had to predicted make a model.And finally had to infer. They came in handy.

The enigma box is a mystery to me. There are two holes, the big one on the top and the small one on the top. A tube was jutting out of the bottom. The experiment is, a person pours water in the top. No water comes out of it till250 ml.when it started dripping. Then at 400 ml. it started pouring.

I believe that inside the enigma box is a container on a point. When the water gets full enough it tips the container spilling the water. Were then the water goes into a funnel that leads into the tube. Like at water world with a huge cup that tips on the people. Just without the funnel.

My prediction was wrong. In the enigma box was one single tube when the tube filled up the air pressure kept it going. Until it filled up only a few drips of water came out. The enigma box was really based on air pressure. That is my observation.
