in the plastic industry and used as the base compound for the manufacture of polycarbonate plastic and the resin lining of food and beverage cans. BPA is also used an additive in other widely used plastics such as plyvinyl chloride and polyethylene terephthalate. BPA can leach from these polycarbonate containers under heat and either acidic or basic conditions, as these environmental factors accelerate the hydrolysis of the ester bond linking BPA monomers, leading to the release of BPA with…

Would you stop having children, or not have any children at all if it meant you were saving the planet? The earth’s population is currently 7.3 billion, and according to CBS News, it will increase to 11.2 billion by the end of the century (Schupak). This means that at the current rate at which humans are reproducing, there will not be enough natural resources to sustain life on earth. No more fresh-water. No more trees. No more oil. Mankind will be driven to extinction without these crucial…

million barrels of oil each year” (Schriever). This substantial amount of valuable product could alternatively be used to “keep a million cars fueled for a whole year” (Schriever). Additionally, plastic water bottles are made entirely out of polyethylene terephthalate (PET) plastics. PETs are recyclable, but not biodegradable and break into smaller but everlasting fragments over time. These seemingly harmless fragments “absorb toxins that pollute our waterways, contaminate our soil, and sicken…

list of systems within the body, but the most frequent networks that are messed are the thyroid and the pituitary. These regulate weight gain/loss, growth hormone, and body consumption. The second chemical that affects the human body most Polyethylene Terephthalate (PET), which is used to hold soft drinks, water, juice, ketchup etc. This plastic is considered ‘safe” according to recent research, but there are several issues that should have awareness. Antimony, a metalloid element with toxic…

The purification of bottled water often sounds healthier because it is said to take out the dangerous chemicals that can be found in tap water. However, when tested some cannot tell the difference between tap water and the purified…

Bottled water is an easy alternative when people are on the go. It is harder to find water that is clean to fill reusable water bottles with. According to Pricilla Torres, quoted by Lemanski, “Most of the bottles are made of a plastic called polyethylene terephthalate, or PET, which is supposed to be generally safe, but if heated, the plastic could leach chemicals into the water. There are hazards linked to these chemicals, but ‘the exact health risks are unknown’” (301-02). Although, according…

Introduction and Overview: For this extended essay, I will be working on building and optimizing different sized water rockets to find out the optimum amount of fuel (water) for each the different rocket sizes. I will be measuring the ranges at which each rocket will fly to find out the optimum fuel level. A brief summary of water rockets: A water rocket is made up of a selection of parts to provide its successful launch: the nose cone which will make the rather snub-nosed end of the large…
