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.

Weather fronts

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.
