A good taxidermist must be able to reproduce life like, three-dimensional representations of animals for permanent display. The job incorporates many crafts, such as carpentry, tanning, molding, casting, and artistic talent. C. The majority of taxidermists are se

THC Tetrahydrocannabinol (THC) is the active chemical in cannabis and is one of the oldest hallucinogenic drugs known. There is evidence that cannabis extracts were used by the Chinese as a herbal remedy since the first century AD. Cannabis comes from the flowering tops and leaves of the hemp plant, Cannabis sativa (shown in the picture on the right). For centuries this plant has been wi

Ten Thousand Leagues Under The Sea Cousteau, Jacques-Yves «koo stoh, zhahk eev», (1910-1997), was a French oceanographer, author, and motion-picture producer. He developed many techniques for undersea exploration. In 1943, Cousteau helped invent the aqualung. This breathing device enables a diver to move about freely under water for long periods. Cousteau also developed the first underwa

Tencel Tencel is a cellulosic fiber made from wood pulp from trees grown on special tree farms in the USA where the trees are constantly replanted. The fiber is produced via a special "solvent-spinning" process using a non-toxic solvent that is 99 percent recoverable and recyclable. Because no toxic chemical products are produced during the process, there are no harmful fumes released in

Genetically Modified Organisms Informing The Queens College Campus about Genetically Modified Organisms Background Information: As we discussed in class, Genetically Modified Organisms (GMOs) are a rapid growing problem. They range from the fruits, vegetables, and milk to the animals we use as food. Introducing foreign genes can be combined into the cells of an organism through

The Universe Explained “I want you to share my excitement at the discoveries, past and present, which have revolutionized the way we think. From the Big Bang to black holes, from dark matter to a possible Big Crunch, our image of the universe today is full of strange sounding ideas, and remarkable truths. The story of how we arrived at this picture is the story of learning to understand

The Battery The Battery The battery is a device that converts chemical energy into electricity. Like most important inventions, this device has many different versions originating from the 19th century, making the history of the battery quite interesting. The battery is a combination of many different elements that have spawned new and inventive ways of creation through the comprehe

The Effects Of Human Stomach Acid On E.coli Introduction Livestock, especially cattle, serve as a reservoir of the E.coli bacterium. The microbes live in the bovine gastrointestinal tract, though usually causing no harm to the host. A small share of the bacterium can be shed, however, through the animals’ feces. If at slaughter, the meat becomes contaminated with traces of the harmf

The Brain Parts of the Brain The cerebellum is part of the lower hindbrain, and is important when performing tasks that require timing for example a baseball player hitting a baseball. It also helps in judging whether or not one sound is louder than the other. The cerebellum is the part of the brain that controls moves of attention from one stimulus to another. The cerebral cortex i

The Brain The brain is surrounded by three layers of connective tissue. These three layer nourish and protect the brain. Covering the brain and these three layers of connective tissues is the skull. The skull encases the brain, and is part of the skeletal system. The first layer fo the brain is gray. It is gray because of the billions of neurons. Underneath the gray material is whi

The Brain Of An Athlete Neuron in Action What is the brain' How does the athlete’s brain develop and achieve with precision the complex connections and interactions needed to perform' How does the brain adapt itself to such demands' From the cell to the performance, what have researchers discovered' How does belief, self-talk act as performance enhancement in the intrecate b

The Combustion Of Alcohlos How much heat is given out by alcohols' Plan In this experiment I will test different alcohols to find which gives off the most heat during combustion. The alcohols I am going to test are methanol, ethanol, propanol, butanol, and pentanol. The heat comes from the bonds being broken (endothermic) and made (exothermic). Each bond needs a different amount of e

Amethyst The name for the mineral amethyst comes from the Greek word amethustos which means not drunken. In the first century a famous Greek god wrote that amethyst was named for its color being nearly the same as the color of wine. Early Greeks believed that drinking wine from an amethyst cup would prevent intoxication, or getting drunk. Amethyst is a purple gemstone. Iron and manganese

The Cretaceous Extinction The Cretaceous Extinction There are many therioes and ideas on what caused the Cretaceous extinction but I’m going to focus more on the asteriod theory. Some therioes include: volcanic activity, an exploding supernova, and starvation etc. and I will cover them but mainly on the asteriod theory. The reason is because the asteriod theory is the most common and

Ammonia Production Social Relevance Report Ammonia Production What is Ammonia' Ammonia is a colourless alkaline gas with the formula NH3 and is made up of one part nitrogen and three parts hydrogen. It is lighter than air and has a sharp, stinging odour. Ammonia can be inhaled safely if it is greatly diluted in air, but concentrated ammonia gas can cause suffocation and death. A

The Diamond The Diamond, mineral form of carbon, valued as a precious stone, and also used for various industrial purposes. Diamonds occur in various forms, including the diamond proper, bort, ballas, and carbonado. Bort is an imperfectly crystallized diamond, extremely hard, and dark in color. The term bort sometimes is applied also to minute fragments of gem diamonds. Ballas is a compa

The Disasters Of Cloning Disasters of Cloning It’s amazing how advanced our science and technology has developed over the years. Who would have thought that the creative mind of an intelligent author could actually bring truth to a far-fetched concept' In 1932, Aldous Huxley’s A Brave New World introduced the phenomenon of human beings brought to life, not within a mother’s womb, but in

The Drug Known As LSD The drug known as LSD Introduction LSD has always been a center of controversy in American society, often times because people have been miseducated about its affects or exposed to the media bias. Its physiological affects on the brain and body have become more and more apparent in the last few decades when research neuroscience peaked. The psychological affe

The Human Genome Project The idea of the Human Genome Project first began in a vague way in the 1970s when biologists started to investigate human genes at the molecular level. As biochemical analysis of DNA became possible, it became clear that certain segments of DNA were associated with particular conditions. A range of countries began to map parts of the human genome in the 1980s b

The Effects Of Salt On The Boiling Point Of Water Lab Report PROJECT TITLE The Effect of Salt on the Boiling Temperature of Water PURPOSE OF THE PROJECT To find out how table salt affects the boiling temperature of water. HYPOTHESIS Adding table salt to boiling water will cause the water to boil at a higher temperature. MATERIALS AND EQUIPMENT Table Salt

Ampicillin Resistance The purpose of this lab experiment was to see if a person could use a plasmid (R plasmid) vector containing certain fragments of foreign DNA for ampicillin resistance to be used to transform E. coli (Escherichia coli) cells to give the E. coli cells ampicillin resistance. Ampicillin resistance is needed in order for the E. coli to have the ability to survive in an a

The End Permian Mass Extinction The End Permian Mass Extinction Introduction Think of a world which existed 290 million years ago. As you look out over the terane in front of you, you think that you are on an alien planet. You see volcanoes spewing ash and lava. Beside them is the ocean which is swarming with many different species of echinoderms, bryozoans and brachiopods. As you look

The Ethicality Of Science The Ethicality of Science by Ryan Potter “The world has achieved brilliance without conscience. Ours is a world of nuclear giants and ethical infants” General Omar Bradley.
