Xenon
<view this essay>.... and most of the other noble gases were discovered by Sir William
Ramsey and M.W. Travers from England in 1898. The two scientists discovered it
mistakenly while experimenting with crude krypton, another noble gas. They were
separating the elements in the crude krypton through a process called fractional
distillation. In fractional distillation, the process separates two elements
that have different boiling points. Basic-ally, when a sample is heated, the
faster element leaves first, leaving the second element behind. Krypton was
known to have a boiling point at a temperature that is lower than xenon. So the
scientists could predict that heating .....

Preserve The Forests
<view this essay>.... direction of our only planet.
In order to preserve the beauty of this planet, we must cease the clear-
cutting of forests. All old growth forests have been around for multiple
centuries and are cut down daily in a matter of hours in order to produce more
buildings and houses in this already over-crowded world. If the rate at which
we cut down trees is continued without any regulation, the forests will all be
gone in ten years, so we should do mankind a favor and try to preserve what is
left. If the old growth forests are gone, then they can never return because it
takes over five generations to produce one and at the rate that the human
population is incr .....

Bottle Rockets
<view this essay>.... be propelled by something, for our rockets we used regular air and compressed it. Upon releasing the stopper Newton’s first law went into effect which states that for something to move a force must act upon it in this case the gas moving out of the bottle. When the stopper was pulled the pressure in the bottle forced its way down, which applied the force to start the motion of the bottle. His 3rd law can also explain this because the water going down forces the rocket in the exact opposite direction the water goes. Which is why one time when we shot the rocket it flew at an angle. Also it shows why the launchers had stoppers, because if they didn’t the cor .....

He did not understand that the rings were separate from the planet, so he described them as handles. has a dense atmosphere mad up of 88% hydrogen, 11% helium and the remainder comprises traces of methane, ammonia, ammonia crystals , and such other gases as ethane acetylene, and phosphine. has an average temperature of negative one hundred and seventy six degrees Celsius below zero.

Seeing The Vessels Of The Retina
<view this essay>.... blind to be able to see.
I guessed that a person could not see the blood vessels in the back of
their own eyes.
EXPERIMENT
My experiment was not about the tiny blood vessels that you can easily
see on the surface of the eye. It's to do with the larger vessels
All I had to do was take a person into a dark room with my flashlight.
I had them cover their left eye and look down at the floor with their right eye.
I held the flashlight up towards the ceiling under their right eye, but they
kept looking at the floor, not the light.
RESULTS
I am writing down what everyone recorded for me. I am first:
JOSH: I could see black blood vessels with orange i .....

Nuclear Energy
<view this essay>.... kinetic fission particles, only that the properties
of the nuclear energies nucleus are radioactive. These radioactive nucleuses
can be contained and used as fuel for the power. Most of this power is fueled
by uranium isotopes. These isotopes are highly radioactive. The isotope
catches the fast moving neutrons created by the splitting atoms, it repels the
slower moving protons and electrons, then gathers the neutrons and pulls them
inward. While all these atoms are flying about they smash together then split
many of many times, this is when the reactor grabs and pulls in the frictional
energy to be processed into electrical watts.
This usually causes hea .....
