Solar Vehicle

For my solar vehicle project i choose to design a boat. At first i was going to make a boat out of four water bottles rubber banded together. My water bottle project wasn't so successfully i couldn't find a way on how not to get the motor wet. I got a bit frustrated..but then my friend Chris brought in cookies to class and with his cookie tray i figured that it would be possible to make a boat with it. Chris helped me out on placing the motor.

The power of the sun is going to work by allowing my boat to move on water. With the solar panel i will receive enough sunlight to power my motor and allow my boat to move by spinning the propeller.

The design of my boat vehicle is pretty basic the boat is basically the lid of a cookie box and my propeller is a wooden popsticle stick with my name on it .. and the motor is on the inside. The spinning metal of the motor is poked though the cookie lid and there is black plastic piece of scrap under to make it balance and it is tapped so it wont move.

My project although is still unfinished. I have to add, of course the solar panel and also some kind of pieces on the bottom of my solar panle to make it stay put and recieve enough sunlight.

The Wiches Broom

Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. This is the west end of the Veil Nebula Nebula. The rampaging gas gains its colors by impacting and exciting existing nearby gas.

Galileo's use of the telescope is so valiable to science becasue we wouldn't be able to see and obsevate all this stuff that are thousands or even millions of miles away, it also wouldnt of given the scientist throughout the years the idea of the invention of creating the highly developed telescopes that we have today.

how humans affect climate

                 How Humans affect climate change

One way humans affect climate change gradually is by millions of people around the world burning of gasoline by automobiles that release carbon dioxide and other types of air pollution that contribute to global climate change. The largest climate contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. One large impact that affects the earths climate is the burning of coal in factories and also in restaurants causing an abundant of smoke and smog that pollute the air in the atmosphere. This usually occurs in large cities such as Los Angles and New York.

Coriolis effect 

The Coriolis effect is an intertial force, it is a deflection of moving objects.
The two reasons for the coriolis effect are

• the Earth rotates eastward
• the tangential velocity of a point on the Earth is a function of latitude

Jet Streams

Jet streams are fast flowing, air currents found in the atmospheres.

Trade Winds

The trade winds are the prevailing patterns of easterly surface winds found in the tropics.The trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere.

Cyclones

A cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth.

Anticyclones

An anticylcone is the oppisite of a cyclone, it is a weather phenominon. they are defined as as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern Hemisphere.
