Observing Water's Proprties

2009-05-11T15:08:00.000-07:00

The observations that we did were about the properties of water and what are they. The properties consist of a negative charge and two positive charges.
The prediction that I thought of was that the polar molecule would be destroyed when it flows down something or is desroyed by other molecules.
The outcome of the procedure was that the polar molecules stayed together and actually made bonds with other molecules.
This happened beacause the one of the positive charges and one of the negative charges of another polar molecule got attracted together. The polar molecule stayed together because they would not break their bonds with another polar molecule. Bonds tend to form and disconnect very often.

This is a polar molecule.

A nebula.

The last blog post that I will make is right here. The things I'm going to talk about is what were my favorite topics in lessons from Science class.
In Astronomy, my favorite topic that we went over was when we were studying astronomers that thought what the solar system was formed like. When we were studying about astronomy, I liked what I found out about other ways to look at the solar systems or nebulas.
In Weather and Climate (Earth's Atmosphere), my favorite topic was when we studied about weather fronts. When we were studying about weather fronts, I finally knew what the curve and arrows or half circle meant on a weather channel.
In Geology, I liked the volcano field trip. When we were studying volcanoes, the volcano from the inside became more clearer than what I studied back in 3rd grade.
In Weathering and Erosion, I liked when we studied plate tectonics. The plate tectonics are the plates that are under the ocean and make earthquakes.
In Earth's Water's, I liked to find out about what are polar molecules. The polar molecule is a molecule that is made up of two positive charged and one negative charged particle.

Where Does Colorado Springs Water Come From

2009-04-30T07:28:00.000-07:00

About 75% of the water that Colorado Springs uses is from mountain springs in the areas of Aspen, Leadville, and Breckenridge-Colorado. Protective pipes transfer this water down from the mountains to be stored in local reservoirs like Rampart Reservoir and Catamount Reservoir.
Rampart Reservoir is a 500 surface acre lake located between the United States Air Force Academy and Woodland Park-nestled in the middle eastern slope of the Rocky Mountains. Catamount Reservoir is a 210 surface acre lake on the North Slope of Pikes Peak.

Penny Lab

2009-04-20T14:06:00.000-07:00

The Penny Lab is an activity to see how many water droplets can go on top of a penny without the water coming off the penny.
I thought that there would only be 4 water droplets that would be able to get onto the penny.
I found out that 9 water droplets could go on top of the penny without it coming off.
The water molecules inside the water droplets were constantly breaking apart with their positive and negative charge. Also, water molecules were bulding up inside the water droplet, so it would eventually come off the penny.

Water

I am a tourist looking at dam. I'm at the Hoover Dam, between Nevada and Arizona on the Colorado River. The Hoover Dam is very large, about 1244 feet long and 726.4 feet high. The sight from the helicopter is great, you could see Lake Mead from where the helicopter flew over. Most of the sounds are water moving, cars, and helicopter. This dam revels that Earth's water is very unpredictable from the time that the Hoover Dam wasn't built to the time it was built. A relationship between humans and Earth's water is trying to learn more about the Hoover Dam. This large dam one of the largest dams in the world. Also the Hoover Dam is probably going to stay the longest to stay standing.

6. People can protect themselves from danger of earthquakes by: bolting their house to a good foundation, bolting bookshelves to a wall, strapping a water heater to a wall, have beams bolted tightly to each other, bolting a brick chimney securly, and having no heavy objects above a bed. Also, taking cover under a strong table or inside a bath.

Atmospheric Factors Affecting Earth

2008-11-17T17:09:00.000-08:00

This is my paper.

Ozone

2008-11-11T07:59:00.000-08:00

The ozone is a layer inside the stratosphere that protects Earth from UV radiation. Without the ozone, we would all be burned due to UV radiation. Ozone depletion is when a hole in the ozone appears. This is a sign of global warming caused by smog and other gases.

Greenhouse Effect

2008-11-11T07:45:00.000-08:00

The greenhouse effect is when light from the sun travels into a glass like containment. The light gets into the glass like containment and tries to get back out. The glass protects the light so it will never come out until the light is absorbed. This is what happens with atmosphere. The sunlight travels to Earth and tries to go back out. But the troposphere acts like the glass of the Earth. The sunlight is either absorbed into the Earth, goes back out to space, or gets absorbed into gas molecules.

London Type Smog

2008-11-04T07:52:00.000-08:00

London-type smog was caused mainly by air pollution due to combustion of coal and emission of sulphur dioxide (SO2) and dust. Such pollution mixed with fog can produce droplets of sulphuric acid (H2SO4) suspended in the air. When in 1952, in London, the concentration of SO2 during a smog event exceeded 3.5 mg per 1m3 of the air (or 3500 ug per 1m30), it caused massive cases of decease(Note: 1mg is 0.001g; another unit is 1 ug which is equal to 0.000001 g. So 1g=1000 mg or 1000000 ug).

The Atmosphere

2008-10-29T07:24:00.000-07:00

Early Greeks considered "air" to be one of four elementary substances; along with earth, fire, and water. Air was viewed as a fundamental compound of the universe. Measurements such as temperature and pressure not only help us predict the weather, but also help us look at long-term changes in global climate. Nitrogen takes 78% of the Earth's atmosphere. Oxygen is 21% of the atmosphere. Carbon monoxide is very deadly to humans, animals, and plants.

Constant Components : Nitrogen (N2) 78.08%, Oxygen (O2) 20.95%, Argon (AR) 0.93%, Neon, Helium, Krypton 0.0001%

Variable Components : Carbon Dioxide (CO2) 0.038%, Water Vapor (H2O) 0.4%, Methane (CH4) Trace, Sulfur Dioxide (SO2) Trace, Ozone (O3) Trace, Nitrogen Oxides (NO,NO2) Trace

Space Exploration

2008-10-08T07:37:00.000-07:00

The Space Program

The space program is a program that let humans go in space
The space program started in 1958
NASA stands for National Aeronautics and Space Administration
The first human to orbit Earth was Yuri Gagarin, aboard Vostok 1
The first American in space, Alan Shepard, was aboard Freedom 7
The first American to orbit Earth was John Glenn, aboard Friendship 7
Between 1969 and 1972, the United States and the Soviet Union sent many unpiloted spacecrafts to explore the moon
In July 1969, three American astronauts circled the moon aboard Apollo 11
Once in orbit, Neil Armstrong and Buzz Aldrin entered a tiny spacecraft called Eagle
On July 20, the Eagle descended toward a flat area on the moon's surface called the Sea of Tranquility
The Eagle landed and said that they landed safely on the moon and the mission control in Houston, Texas cheered and whooped
"One small step for man, one giant leap for man kind." , stated Neil Armstrong

A lady is playing with that playset. It is on a magizine, that a man is holding. This man is on cruise ship. The cruise ship is on a poster which is on a bus. That is in a city, on a t.v. A man is watching it, in the desert, ona poststamp. The poststamp is in Jamaica. And a man is watching them, in a plane, that is over a sea, that is in the world. The world is in space. The space is infinite.

Enigma Box

2008-08-29T07:41:00.000-07:00

A black box that has two holes, one small and one large. There is a tube at the bottom that drips once every time it is filled with water. After at least 470 ml of water it poured out water. A bucket that is under the tube is being filled when it pours. At least one minute after the it starts it stops.

It might have to do with the shape of the box. The water might be building up and when it overflows it might go over an edge and hit a lever that might open a trap door. It also might have to do with the water. It also might have to do with the tube. Maybe it is just curved upward to point to the top so it can capture water when it fills up.

Inside the box is a tube that curves like a fish that was sketched.
