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.

Observing waters properties on a penny
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
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
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.
