what i learned in the electricity lab today 7/23/2012

I learned how to spell electricity which I didn’t know how to spell before. I also learned that voltage=current times resistance. I found out that protons are 1000x bigger than electrons.

Electricity is the movement of electrons and we create power by tapping in to the current of energy and make a new circuit, wich can be used to supply power to any object that needs it. Currents require a full connection to function properly.

If a river were to describe what a current, voltage, and resistance were this would be the anser.

Current: The width of the river.

Voltage: The steepness of the drop the river is on.

Resistance: How hard it is for the river to flow.

This is what I learned in Mr.Patels science class on 7/23/2012

Tesla VS Edison

The rivalry between Nikola Tesla and Edison started after Tesla was working for Edison, (after he had just invented the light bulb) and was told to fix the bugs in Edison’s new form of moving electricity which was called DC, or direct current.  When Tesla did this, it upset Edison, so he did not pay Tesla money he said he would.  After that happened, Tesla quit.  Edison then vowed to discredit Tesla’s work.

In 1888 Tesla developed a better way to move electricity.  When Tesla found this way, he named it alternating currents or (AC), replacing the bad direct currents, or (DC).  The main difference was DC couldn’t be sent long distances and AC could.  This was the start of long distance electric broadcasts, like TV and radio.

When George Westinghouse heard of AC, he offered to help fund the idea by paying Tesla $2.50 dollars for every kilowatt sold.  After he received the money, Nikola Tesla finally had the money needed to continue his experiments on his own.

In the First World War, the United States Government needed ways to fight the Germen submarines, they went to Edison.  When Tesla heard, he offered to make a way to see submarines using electrical pulses.  These pulses later became known as sonar.  Due to Edison getting the first opportunity to develop technology for the United States, sonar would not be fully realized for another 25 years.

When Edison was trying to disprove Tesla’s inventions, he accidentally invented the electric chair.  Edison was trying to prove his DC was safe by putting it in people, unfortunately this ended up becoming the way to put people to death.   When Tesla did the same with AC, he ran it through his body to power a light bulb without harming himself.  To more fully impress the crowd, he then shot it out of his finger into the crowd.

In the end, a prize was created to celebrate creative minds.  Tesla ironically received the Edison Prize.  So all of Tesla’s great idea’s which help shape todays modern technology, was sadly frowned upon when first introduced.  At the end, it was a hit to the face when he received a medal named after his lifelong rival, which really should have been named after him.   When Tesla died in 1943, over 2000 people attended his funeral.

famous Latino scientist

The famous Latino scientist i researched was Pedro Flores. He is know for bringing the yo-yo to America. He   came to America in 1915 and attended high school for 2 years at the high school of commerce in California. Then he attended 2 collages Berkeley and Hastings collage of law. He first started to make yo-yo’s in Santa Barbra, California. In the 1930’s to the 1932’s Pedro sold his interests of the company to Donald Duncan for around $250,000. In 1954 he started the Flores Corp. of America witch didn’t make yo-yo’s for long only in the 1950’s.

squid struchure essay

The squid’s body is made up of 2 main body parts the mantle, which contains the internal organs, the jet propulsion system, the fins, and the digestive and reproductive systems. The other main part is the head which contains the eyes, beak, and tentacles which serve as arms for grabbing food.

 

The mantle is a ½ inch thick skin like substance which protects the internal organs such as the 3 hearts, the gills, the stomach, the ink sack, and the reproductive system. The mantle is also covered in small dots called chromatophores which allow the skin to quickly change from the colors red and white. The jet propulsion system allows part of the mantle to take in water then quickly shoot it out the other side to push the squid forward.

 

The general size of a small squid is 1-2 feet. Some squid that were found size to about 46 feet or 13 meters. Some people believe in a version of a giant squid normally referred to as the kraken! This is also another name for a 1,000 pound squid found of the coast of Antarctica which at the time was the largest cephalopod found in that time.

 

The head of the squid despite belief has NO brain. It holds the beak which is NOT made of calcium like human teeth, but is made of chitin and a cross link protein substance which is tough like calcium. The squid has 2 eyes one on each side of the head, the eyes are surprisingly big for its size. At the bottom of the head are 8 tentacles and 2 arms.  People think they just have suckers but in each sucker is a small ring of teeth.

 

Inside the mantle for female squid is a sack to hold the eggs. For male squid when they mature one of the tentacles instead of having suckers and teeth have padding like substance for mating. When mating season comes around a male squid puts the special tentacle in the female to release special male squid stuff to fertilize the eggs.

 

Some weird things about the squid are when a tentacle is cut of it will not grow back. The material which makes the tentacles is called muscular hydrostat. The ink sack is hidden by 2 nidamental glands which are anterior to the gills. The stomach of the squid lies directly in the middle of the entire body. THE END

First homework assignment!

Hi Robert Van Oden my partner is Victor is blog info is victorpascual64.wordpress.com we are studying the basic inner working of squid also weaknesses and all appendages.

 I found an article at national geographic and it talks about the squids ability to use its arms teeth to grab pray and drag them to the mouth. The squid has 6 legs or just normal appendages to help grab objects and 2 special arms for sharp teeth that are longer. This gives the squid a huge advantage for hunting other animals. This is the article :http://animals.nationalgeographic.com/animals/invertebrates/giant-squid/

 

The second article I found was explaining the basic layout of the squid and how the parts would be used in everyday life or survival. The teeth are in a small circle with around and average of 8 to 10 teeth. Each tooth is a small little razor like tooth good for holding on to pray while the squid devourers it. This is the article : http://www.sardineking.com/squid.html

 

The last article I found talks about the squids eating pattern. I found that the most affective way for a squid to catch and kill prey is to chase it until is is tieed then use jet propulsion to boost toward the prey and devour. They Manley eat small fish and other squid. This is it http://jeb.biologists.org/content/203/18/2851.full.pdf

These are the basic workings of squid witch help them survive daily life.! ALL DONE 🙂

first day

It’s weird to be in class in the summer, its funny 2 days ago i was playing home run derby with chunks of concrete and a sledge hammer with my older brother. My interests are music and soccer and old stuff so history i guess. I was really mad that Spain won the euro cup in 2012 and the world up in 2010. My history in science involves fire, and mixing chemicals to make fuel for fire. I also learned to make tiny explosive toys like cherry-bombs.

I guess my expertise would be chemicals mixing and using. One thing i know that i don’t know that i would like to know is how do bears run so fast because they are REALLY big?
