Science Fair Research Paper Zachariah Alzubi and Yosef Ismael Best Methods of Recycling Plastics Recycling has grown rapidly over these past few decades. Almost every single household in America has a recycling bin. You can find recycling bins anywhere like in your school or at a dumpster nearby and I’m sure there are plenty at home. You can almost recycle anything from glass, to Styrofoam, and especially plastic. There are many things around your house that are probably made of plastic, if you’re

MEASUREMENTS IN SCIENCE Introduction: In this lab, a sample of metal and a sample of plastic were identified using their respective densities. Different materials have a unique density which is defined to be the amount of mass inside a specific volume of the material. The density does not change with the size or shape of the object, so it can be determined using any size sample of the material by dividing its mass by its volume. The mass of a material can be found easily using an electronic balance;

EXECUTIVE SUMMARY Formosa Plastic Group (FPG) was founded in 1954 and headquartered in Taipei, Taiwan with over 47,000 employees. FPG was the largest private diversified chemical company that produced and sold a broad range of products which mostly related to plastic. It also operated 6000 bed hospital, medical college, a nursing school, and a technical college. FPG was organized into three major corporations and other affiliated companies. Those three major corporations are Formosa

Baycol is a drug containing 0.2, 0.3, 0.4 or 0.8 mg of the active ingredient cerivastatin sodium and inactive ingredients: mannitol, magnesium stearate, sodium hydroxide, crospovidone, povidone, iron oxide yellow, methylhydroxypropylcellulose, polyethylene glycol, and titanium dioxide. Cerivastatin sodium is sodium (C26H33FNO5Na) with molecular weight of 481.5 and the following chemical structure: Clinical Pharmacology Baycol is a drug that was used to reduce cardiovascular diseases created by

Strain 4. Procedure (Determination of Tensile Properties) 4.1 Materials General Purpose Polystyrene (GPPS), High Impact Polystyrene (HIPS), High Density Polyethylene (HDPE) and Polypropylene (PS). 4.2 Equipment Lloyd Tensile Testing Machine 4.3 Steps 4.4 Experimental Precaution: 1. Check the force that is applied in the load cell is correct. 2. Take into account the zero error when measuring

In order to better understand this lab one must first understand about polymers and their monomer units. Polymers are substances containing a large number of structural units joined by the same type of linkage. The small molecules that make up these polymer chains are called monomers. Polymers in the natural world have been around since the beginning of time and are found many places in nature. Starch, cellulose, and rubber all possess polymeric properties. Cellulose and starch are actually polymers

(Ke E 10,11) Explain, using a diagram, the use of Fractional Distillation in an Oil Refinery. How is this method used to help produce chemico-technical products (fuels,solvents, etc). Due to having different boiling points the substances in the crude oil can be separated if/by using fractional distillation. The crude oil is braked down and its steam condenses at different temperatures in the fractionating column. Every fraction contains hydrocarbon molecules with very similar numbers of carbon atoms

Aquaponics is a combination of two words: Aquaculture and Hydroponics. Definition: It is the system that combines the conventional aquaculture with the hydroponics in a symbiotic environment.’ This is an age-old practice of plant cultivation utilizing the water from the aquaculture system where the by-products are broken down by the bacteria and utilized by plants as nutrients, and the water is then sent back to the aquaculture system. This works as a perfect symbiotic environment where the fish

the mould is left to cool the hollow component is removed Advantages of blow moulding: Can easily produce high or low number of components. There are many different materials to choose from and also tooling is cheaper compared to injection moulding. The component is fully produced instead of just a part being produced and also there are no cores. Disadvantages of

PHASE BEHAVIOR:- Melting Point:- The temperature at which polymer transmit into crystalline form to determine the melting point. The polymer of low-molecular substance exist very low melting point and this happened when polymer chain is dispersed. In physical state melting point is very difficult to calculate. Polymer will decompose at high temperature rather than melts. It is also known as crystalline melting temperature. Glass Transition
