MY SCIENCE FAIR PROJECT

Silly Putty History

James Wright, an engineer at General Electric's New Haven laboratory, invented silly putty in 1943 when he accidentally dropped boric acid into silicone oil. Dr. Earl Warrick, of the Dow Corning Corporation, also developed a bouncing silicone putty in 1943. Both GE and Dow Corning were trying to make an inexpensive synthetic rubber to support the war effort. The material resulting from the mixture of boric acid and silicone stretched and bounced farther than rubber, even at extreme temperatures. As an added bonus, the putty copied newspaper or comic-book print.


How Silly Putty Works

Silly Putty is a viscoelastic liquid. It acts primarily as a viscous liquid, it can also have properties of an elastic solid, too. Silly Putty is primarily polydimethylsiloxane (PDMS). There are covalent bonds within the polymer, but hydrogen bonds between the molecules. The hydrogen bonds can be readily broken. When small amounts of stress are slowly applied to the putty, only a few of the bonds are broken. Under these condition, the putty flows. When more stress is applied quickly, many bonds are broken, causing the putty to tear.

RELIGION IN SCHOOL

WHAT IS INTELLIGENT DESIGN AND DO YOU THINK IT SHOULD BE TAUGHT IN PUBLIC SCHOOLS?

Well I think intelligent design should be taught in public schools. The reason why I think it should be taught in public schools is because when you have faith in something you will stick to what you believe in. When they teach intelligent design in schools, they can tell you that you don’t have to believe in God but that intelligent design is a way of life that people and or some scientist figured out that there is a creator or one who had a plan for being on earth.

The idea that an organism’s complexity is evidence for the existence of a cosmic designer was advanced centuries before Charles Darwin was born. Its best-known exponent was English theologian William Paley, creator of the famous watchmaker analogy. If we find a pocket watch in a field, Paley wrote in 1802, we immediately infer that it was produced not by natural processes acting blindly but by a designing human intellect. Likewise, he reasoned, the natural world contains abundant evidence of a supernatural creator. The argument from design, as it is known, prevailed as an explanation of the natural world until the publication of the Origin of Species in 1859. The weight of the evidence that Darwin had patiently gathered swiftly convinced scientists that evolution by natural selection better explained life’s complexity and diversity. “I cannot possibly believe,” wrote Darwin in 1868, “that a false theory would explain so many classes of facts.”

If they can teach the theory of evolution, and it is still not a known fact that we were apes or monkeys and scientist are not sure that we were monkeys and etc… We should be able to learn about Intelligent Design because we as students need to be aware of what is going on and know our history about science.

Geometry Project-Koch



NHD Topic Essay

My topic is on the Los Angeles riots. My topic took place in Los Angeles California in South Central. It all started in 1992. The famous Rodney King was beaten severely by L.A cops. Mostly African Americans and Hispanics were harassed by cops because of their race. A lot of people were stealing from stores and etc… They figured they wouldn’t get caught because of all of the commotion that was going on.

I chose this topic because it seemed so fascinated to learn about. This topic grabbed my attention because I seen a movie about the L.A riots, which I really enjoyed and had entrance in. In numerous occasions of rioting, arson, and looting were taking place at the time of the riots in L.A. Live helicopter news reports showed the air over several neighborhoods appeared to be filled with smoke. Los Angeles Fire Department officials report that as many as nine (9) large stores are burning, and that numerous cars have been "torched" in an attempt to block intersections. That is what I seen in the movie. Also the movie was based on a true story. So I figured why not do a NHD project that I will really enjoy and have a little bit of knowledge about already.

I want to learn more about the L.A riots. I want to know if there were any court cases other than Rodney King, where cops got arrested or charged with any accounts. I also want to know if any large gangs or organized groups got busted.

The L.A riots connect to this year’s theme “Conflict and Compromise” because the conflict was that cops were taking advantage of certain people. People was robbing and stealing from stores. The compromise was that it all ended slowly but surely.

FOR IMMEDIATE RELEASE-EMERGENCYNET NEWS SVC.-04/30/92-1700CDT

MAJOR RIOT IN LOS ANGELES, THIRTEEN DEAD, 192 INJURIED
Los Angeles, CA - Following a jury verdict which acquitted four L.A.P.D. officers of charges resulting from the video- taped beating of motorist Rodney King, Southcentral Los Angeles erupted in a violent and deadly outburst of arson and shooting. Local police and emergency medical services officials report the deaths of as many as nine (9) people and injuries to another 138.

As the sun rose over Los Angeles, more than forty (40) major fires still burned out of control. They were part of an estimated 140 fires that were set in the Southeast and Southcentral parts of the city. During the night, firefighters and paramedics were hardpressed to keep up with the requests for emergency response to more than 140 fires. Reportedly, they came under sniper fire on several occasions, from rooftops surrounding the fire scenes. One Los Angeles firefighter is reported in stable, but serious, condition at an area hospital following his being shot in the face while fighting a blaze.

According to a police spokesman at least five (5) people have been shot by police and one was killed in a gun-battle in the city's Inglewood area. A spokesperson for the Daniel Freeman Hospital says that they have treated at least fifty (50) citizens with "riot-related" injuries. Emergency Medical Services (EMS) officers say that all available city ambulances are "on calls" and that mutual aid from Los Angeles County and Orange County has been requested. At least 192 people are reported to have been taken to various hospitals in the L.A. metropolitan area.
