One of my favorite TV shows is Mythbusters on the Discovery channel. One of my favorite episodes was when they drove a full size bus off of a jump. They were testing what was done in a movie when a full size bus was drove off an highway bridge where there was a piece not conected and the the bus reached the other side and the bus didn't even fall off, there must have been some good speacial effects in that movie. They conected remot controls to the bus and drove behind it in a truck. They missed the jump so many times!! but finaly got it, it was awesome when the bus went off because they had a camera inside whith a manakin guy who went bouncing around everywhere. The bus was destroyed and they didn't even get close to the mark that they were supose to hit for the movie, must have been lots of speacial effects.

Another episode of mythbusters that I watched, they were testing grese fires. The myth was a 30 foot fire ball from an 8oz cup of water in oil. The flame got higher than 30 feet. this has a lot to do with sience because the water goes from room temp to the heat of the oil 400 some degres and explodes.

Almost everything involvs energy, like: potential, kinetic, chemical, sound, gravitational, mechanical, motion, nuclear, heat and light, and some others.
Everything we do involves those energies. Example: if you are in your car, driving along, that is kinetic energy. but if you are at a stop light that is potential
energy
. I remember it as you have the potential to move by you aren't actually moving.

Static Electrictiy:

Do you remember when you were on the playground in elementry school, and went down the slide then went up to someone and "shocked" them?
That little shock was a buch of electrons which are particles of an atom being let out all at one time, because you build them up as you go down the slide.
Other static electricity:
  • socks or shoes on carpet- also building up electrons, and all let out at once whith one elecrical shock.
  • a ballon rubbing on your head- actually pulls the electrons out of your hair leaving a positive charge (protons/nutrons) in your hair.

Current Electricity:

Current electricity is the electricity that you use in your house. If you plug something in to the wall, there is a constant flow of electrons to the wall
outlet.

A light bulb is an example of current
electricity because when the light is
on there is a constent current of electron
flowing to the light bulb.


The Invention of the Light Bulb:


Invention: electric light bulb

When: in 1879

Function: An electric lamp in which a filament is heated to incandescence by an electric current. Today's incandescent light bulbs use filaments
made of tungsten rather than carbon of the 1880's.

Inventor: Thomas Alva Edison

Birth: February 11, 1847 in Milan, Ohio

Death: October 18, 1931 in West Orange, New Jersey

How the earthquake in Chile could change the Earth's axis:

The 8.8-magnitude earthquake that jolted Chile on Saturday was felt as far away as São Paulo. But NASA scientists are proposing that its repercussions are truly global in a geophysical sense: it likely shifted the Earth's axis by about eight centimeters.

The fault line under Seattle could be bigger than anyone thought, according to new research conducted by a University of Washington graduate student.
Beth Martin found evidence that could mean quakes along the fault line could be larger, and even trigger a tsunami.
The Nisqually earthquake that rocked the Northwest eight years ago was a 6.8 magnitude.
The quake, centered deep in the Earth, caused a lot of shaking and some damage.
But the ground didn't rise up like it did 1,000 years ago. That's when scientists believe a 7- to 7.5-magnitude earthquake hit the more shallow Seattle fault zone that runs from Sammamish, through Seattle and out toward Bremerton.
Scientists believe some areas rose 18 feet during the quake, that the southwest tip of Bainbridge Island rose out of the Puget Sound, and so did much of Alki Point in West Seattle, which is now full of homes.
The quake also generated a tsunami - a wave possibly six feet high - when it hit Elliott Bay in Shoreline.
And now Martin says she's gathered evidence that the Seattle fault zone could be much bigger than we think, and a quake could spread damage much further west.
Martin's evidence comes from, of all things, clams. They're carbon-dated back to that big quake and found in soil samples she took in the tide lands near Gorst, much further west from where scientists believed the fault ends.
"So somehow this area went from a tide flat with clams in it to a cedar forest. So that's my evidence that everything went up," she said, pointing to the soil sample.
If the shallow Seattle fault is longer, scientists say another quake could do more damage and trigger a bigger tsunami.
Scientists say they aren't sure exactly where the fault line begins and ends.
And in case you were wondering, yes, an earthquake underneath Lake Washington could generate a tsunami.

An earthquake is a naturally induced shaking of the ground. Earthquakes are
caused by the fracture and sliding of rock within the earth’s crust. The earth’s
crust is divided into eight major pieces (or plates) and many minor plates. These
plates are constantly moving, very slowly, over the surface of the globe. As
these plates move, stresses are built up in areas where the plates come into

contact with each other.

Signs Of Global Warming:

We are seeing extreme signs of global warming this year, like we have never seen in years past. Just hear in Western Washington our "winter" has been more like spring or summer. The flowers have bloomed already and are starting to fall, because we get cold spells too. Just a few days ago it was snowing, when the day before it was over 60 degress.

Radiating Heat:

Radiating Heat is the heat that radiates off of things.
Example 1: If you have ever walked by a big TV when it has been on for a while you can feel the heat coming off of it.
Example 2: If you rub your hands together for about 5 seconds then put them as close to your cheeks as you can without touching you can feel the heat coming off your hands.

Sound Waves


Sound is a series of longitudinal or compression waves that move through air or other materials. Sound does not travel in a vacuum.
Like any waveform, sound has the characteristics of wavelength, frequency, amplitude and speed or velocity. Sound waves are created by the vibration of some object, like the cone in a radio loudspeaker. The waves are detected when they cause a detector to vibrate.

Light Waves



Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. Water vapor in the atmosphere can also break apart wavelengths creating a rainbow.

Cones in our eyes are receivers for these tiny visible light waves. The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us.
The color of an object that we see is the color of light reflected. All other colors are absorbed.
Light bulbs are another source of visible light waves.

Microwaves:



Microwaves have wavelengths that can be measured in centimeters! The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven.
Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke.
Shorter microwaves are used in remote sensing. These microwaves are used for radar like the doppler radar used in weather forecasts. Microwaves, used for radar, are just a few inches long.

Ultraviolet Waves:



Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet. The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy.

The near ultraviolet, abbreviated NUV, is the light closest to optical or visible light. The extreme ultraviolet, abbreviated EUV, is the ultraviolet light closest to X-rays, and is the most energetic of the three types. The far ultraviolet, abbreviated FUV, lies between the near and extreme ultraviolet regions. It is the least explored of the three regions.

Our Sun emits light at all the different wavelengths in electromagnetic spectrum, but it is ultraviolet waves that are responsible for causing our sunburns. To the left is an image of the Sun taken at an Extreme Ultraviolet wavelength - 171 Angstroms to be exact. (An Angstrom is a unit length equal to 10-10 meters.) This image was taken by a satellite named SOHO and it shows what the Sun looked like on April 24, 2000.
Though some ultraviolet waves from the Sun penetrate Earth's atmosphere, most of them are blocked from entering by various gases like Ozone. Some days, more ultraviolet waves get through our atmosphere. Scientists have developed a UV index to help people protect themselves from these harmful ultraviolet waves.

X-Rays:



As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength. This is partially because X-rays have very small wavelengths. It is also because X-ray light tends to act more like a particle than a wave. X-ray detectors collect actual photons of X-ray light - which is very different from the radio telescopes that have large dishes designed to focus radio waves!

X-rays were first observed and documented in 1895 by Wilhelm Conrad Roentgen, a German scientist who found them quite by accident when experimenting with vacuum tubes.
A week later, he took an X-ray photograph of his wife's hand which clearly revealed her wedding ring and her bones. The photograph electrified the general public and aroused great scientific interest in the new form of radiation. Roentgen called it "X" to indicate it was an unknown type of radiation. The name stuck, although (over Roentgen's objections), many of his colleagues suggested calling them Roentgen rays. They are still occasionally referred to as Roentgen rays in German-speaking countries.
The Earth's atmosphere is thick enough that virtually no X-rays are able to penetrate from outer space all the way to the Earth's surface. This is good for us but also bad for astronomy - we have to put X-ray telescopes and detectors on satellites! We cannot do X-ray astronomy from the ground.

•The distance form Earth to Mars is 55.7 million km.
The Atmosphere:
•The atmosphere of Mars is very thin, in this environment without oxygen and special gear. The atmosphere is mainly composed of 95 percent carbon dioxide. However, at times, the atmosphere can also contain dust particles.
The Land:
•Mars is called the "red planet" because of the iron-oxide dust that gives it the red color. The fourth planet from the sun is a cold world, as one might expect, with the only "water" so far discovered in the form of ice at the poles.
The Size:
•Mars is roughly half the size of the Earth. It has a diameter of 4,222 miles, compared to Earth's 7,962 miles at the equator. Mars is 53% as large as our planet; this means that Mars has a gravity that is less than 40% of what we feel on Earth. Mars has an atmosphere, but it is less than one percent of ours and is comprised mostly of carbon dioxide.
A Day On Mars:
• Just like Earth, Mars has sidereal days and solar days. A sidereal day is the length of time Mars takes to complete one rotation on its axis compared to the background stars. A sidereal day on Mars is 24 hours, 37 minutes, and 22 seconds. A solar day is the length of time it takes for the Sun to return to the meridian. Because Mars is orbiting around the Sun, this position moves a little bit every day. The solar day is 24 hours, 39 minutes and 35 seconds.
Mars has two moons they are:

Light Travleing

Have you ever heard of a light year?

A light year is the distance light travels in one year.

It takes time for light to travel even though it travels so fast.

The sun is 93,000,000,000

It takes eight minutes for the sun's ligh to reach earth.

The weather is different in different places, as you probably know. This summer I am going to Minnesota and in the summer it is warmer there than it is here in Seattle. There is also more consistant warm days compare to here where we have three days of sun and 100 degree wheather then rain. There are more bugs there too if you are going to the midwest you better bring long clothes and bug spray, because there's a lot of mosquitos.

Why do you think it is warmer and colder in the summer and winter in the midwest?​

Minnesota is in the middle of the U.S and Washington is near the water. Western Washington is like a big rain forest with changing teperatures.

Why do you think there are more bugs (mosquitos) in the midwest?

Minnesota, the land of 10,000 lakes+. Mosquitos are atracted to water, and in the summer is when the come out more they are atracted to light and must be atracted to heat too.

When you are at the beach have you ever wonder how and, or why the ocean's tides rolls in and out? The moon is what pulls the earths tides. It is amazing that the moon has enough gravitational force to pull our tides, but it does. On the apollo 11 mission to the moon the astronats could barely stay on the moon because there was so little gravity. They could jump up high in the air. It is almost like the earth and the moon are fighting with eachother, becuse the moon pulls the water out and the earth pulls it back in. If the moon can pull the whole ocean shores how come it doesn't pull the water out of our cups? Now that I don't know.
