SCI207 final lab paper

The process of producing my Senior Science SciTech Final Summative was quite lengthy and moderately difficult. To start, choosing a connecting course was difficult as I only had Advanced Functions and English as options. When I did choose a course to connect to, it was fairly easy to find a topic relating to Physics as I could choose anything as long as I created a research report to satisfy the requirements to my connecting course. Moving on, the research component was quite difficult and I found it to be the hardest part of this summative. This was due to the fact that the topic I chose was not fairly established. Although there was research available for me, I often found myself connecting the dots, as it was not so straightforward. However,

Please briefly describe the different types of water pollution mentioned throughout the "Poisoned Waters" video. Fertilizers, Nitrogen and Phosphorous caused algae which poisoned the waters. It caused a dead zone. The farmers who own chickens was allowing the manure to pollute the water. The humans race is all responsible as we pollute our water by throwing garbage into it. Soap, household cleaning agents, toothpaste, and other plastic, lubricant and fuels are all poisoning our water.

In contemplating my topic to write about I was having a mild amount of difficulty, not too much but you could say I was confused. Then I heard a knock at the door, when I answered I was given a pamphlet that informed me of the contamination present in out water. One of the issues involved talked of superfund contamination clean up, this was new to me so to the internet I went.

The discovery of free fetal DNA circulating in maternal blood during pregnancy revolutionized noninvasive prenatal diagnosis. Advancements in prenatal diagnosis in the past decade have enabled clinicians to accurately diagnose genetic abnormalities in the fetus earlier and without risk of miscarriage as is associated with amniocentesis and chorionic villus sampling. Sequencing and analysis of the fetal genome has not only improved prenatal diagnosis of chromosomal aneuploidies, but also subchromosomal aberrations and monogenic disorders. This lends parents earlier and more specific information that may guide their decisions during pregnancy to benefit

Domesticated animals are not overly significant to a family. Families typically raise a couple of chickens and ducks. They are allowed to forage around the house during the day, feeding on insects considered pests like ants and sometimes are given maize. At night they are kept in chicken coops tended to by the children.(Johnson) As a people, the Matsigenka are very adaptive and catch all kinds of fish in many different ways.

Students at East Pennsboro Middle School were asked to perform tests on the creek in an attempt to conclude if the creek was or was not polluted. Before going to the creek, one can hypothesize, “If we test the Conodoguinet Creek for signs of acid rain, eutrophication,

It smells like rubbing alcohol. Then they separated the solid from the liquid with a coffee filter. This is the purple liquid separates from sugar-like substances, pebble-like substances and the pieces of aluminum-like foil. Shelstie manually separated the rocks from the sand from the aluminum foil. Then they did fractional distillation. They separated the purple liquid. Now they have 2 liquids that are clear. From fractional distillation, they found that the boiling point of liquid #1 is 74 degrees celsius and 99 degrees celsius for liquid #2. From the coffee filter paper, they did paper chromatography and found out the purple water contains blue and pink color to make purple. They did another smell test. Liquid #1 which they believe is ethanol smells like rubbing alcohol. Liquid #2 smells like nothing and they believe it is water. They found much more characteristic properties of the solids and liquids. The density of liquid #1 is .98 g/ml and .94 g/ml for liquid #2. The density of the pebbles is 1.66

The water is a medium dark color. The fish is still moving. The plants looked chewed up.

The lower the metal is in the group the faster it will react with water. This was seen to be true for both groups one and two. In all cases the metals reacted to form Hydrogen Gas ad a solution that was alkaline. Down the group the electronegativity decreases which results in a metal element losing its valance electrons more easily and hence reacting more

Remove the coffee filter from the funnel after all of the water sample has drained through it. Observe if there are any organisms large enough to see without magnification on the filter paper. Quickly draw them for later identification and include in your lab report.

Depending on the extent of the damage, you can recognize a flood-damaged vehicle by the oil in the car. In a deep flood, water will flood the engine and mix with the oil in the car. If this happens, you’ll see water mixed in the oil on the dipstick. Any bubbles of water, even one, is a sign that you should avoid the vehicle altogether.

Light reflecting off of oil on the surface of water functions in much the same way that light reflecting off of the front and back surfaces of glass does. When light goes reflects off of glass, depending on the thickness of the glass, a different percentage of the light reflects. This percentage can range from zero to sixteen percent. As the glass gets thicker and thicker, it becomes clear that the amount of light reflected works in a cycle. The amount of reflected light starts at zero percent and becomes greater and greater till it is at sixteen percent, and then it goes back down to zero percent. This cycle repeats

The purpose of this lab is to identify the unknown volatile liquid, by finding its molar mass and comparing it to the known molar masses. There are two ways to identify a possible molar mass, and they are to use the Kjeldahl method or the Dumas method (Simmone, Simmone, Eitenmiller, Mills & Cresman, 1997).

There are two major problem regarding groundwater. First, groundwater contamination which also caused by surface water contamination. Pollutants from surface water, such as fish kills, discoloration and odor, is brought downward by water travelling through soil which cause the groundwater contamination (Kenski 3). Because groundwater is less visible compare to surface water, it is hardly noticed and cleaned. Consequently, groundwater quality becomes poor and needs another long procedure to revert it back to usable freshwater. Groundwater contaminations happen around the world that contribute to world’s water shortage.

Water is indispensable for sustaining life on earth. Millions of people lack access to clean water owing to geographical and anthro- pogenic factors. Ground water contamination has always been a reason of concern and it is very
