Science Revision Half-Yearly’s Name the lenses found in a microscope. Eyepiece or ocular lens Objective lens Recall the units used to measure microscopic objects. Micrometres Recall what happens to the field of view as the magnification used increases. As the magnification increases‚ then the amount of the specimen you can see (the field of view) gets smaller. Name two different types of: Light microscope- monocular microscope and the binocular microscope. Electron microscope- transmission

Chemistry paper I decided that I would do technology. Some of the topics I chose for my paper was how chemistry helps with technology by helping with Forsenic Science‚ Crime Scene Investigations‚ the wiring of bombs‚ fireworks and guns preventing premature detonatations‚ and Engineering. Chemistry deals with technology and sciences since technology is used to make experiments. Another example of everyday use is the computer that helps you in your research and communications.

Forensic Science has contributed to our world a great deal. People often misunderstand Forensic Science and believe it is much more capable than it really is. As a matter of fact what you see on T.V. is around 80% false or over exaggerated in some way. To Start of‚ Criminal Investigation is the largest and most known form of Forensic Science. Some of the more known areas include; Fingerprinting‚ Ballistics‚ DNA Identification‚ Fiber Samples‚ Computer Animation‚ Documentation analysis‚ etc. To

Citric acid reacts rapidly with iron‚ but is not itself the rusting of iron. The water in the lemon juice helps iron rust‚ but in the presence of air. The same happens when you open bottle of Coca-Cola‚ including citric acid‚ phosphoric acid‚ carbonic acid and other things in the fall for the taste. Citric acid has an advantage over some other acids‚ because it is less corrosive‚ not as dangerous to the environment‚ while remaining efficient‚ cheap (but not as cheap as the old battery acid).

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

Context of Nursing Paper: LIGHT POLLUTION Global Context of Nursing Paper NURS 4100 Section M March 31‚ 2010 York University Global Context of Nursing Paper: Light Pollution Over the past decade evidence has been mounting that excessive outdoor lighting is not only an aesthetic issue‚ but a potentially hazardous environmental one as well (Berg‚ 2009). Research has shown that excessive lighting is directly responsible for the exponentially growing problem of light pollution (Chepesiuk

Westwood College Project 1 Physical Science Research Paper Evan Duran PHYS212 October 8‚ 2013 Physical science is the study of physics and chemistry of nature. From the materialist and functionalist viewpoints it overlaps the life sciences where ecology studies the evidences of historical facts or evolution. Physics along with Mathematics and Chemistry is one of the fundamental sciences because the other natural sciences like biology‚ geology etc.‚ deal with systems

Process of Photosynthesis Photosynthesis is process by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the air in the presence of light. Green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis
