Water Olympics Lab Write Up

In station one, we explored the idea of density. Density is the amount of cmpactness in an object. We used oil and water, and observed the density of each substance. when pouring the two back and forth, the oil moves slower and the water moves faster and more choppy then the vegetable oil. Seeing this, oil was presumed to be more dense, so I made a hypothesis that if testing the density of oil and water, oil is more dense than its counterpart of water. After a trial of both, it turns out that water has a density of 0.96 g/ml and oil is 0.88 g/ml. Therefore, the given hypothesis stated previously was proven incorrect, showing that density cannot be predicted by looking at something, When looking at a mixed …show more content…

When the water gets to the brink of the cup where it should overflow, surface tension retains the liquid in the cup, this concept is shown at station three. When at station three, to test the surface tension of oil and water, we placed paper clips on the top of the cups of both liquids. The paper clips in the oil sank to the bottom and didn’t create a dome of oil, showing oil has low surface tension. Water did create a dome on the surface and let the paperclips float. The “film” that the water makes allow the clips to rest on the top of the water. Surface tension is important to living things because in marine ecosystems, there might be some bacteria or particles that are on the surface of the water, that if they got into the water, they could hurt animals or break ecosystems. If an oilspill were to occur, those potentially harmful particles and substances will go into the wate, because the oil will disrupt the surface tension, causing the animals to be sick.

At station five, the mixing of water and oil or detergent was tested. When adding the oil, the oil just sits on top of the water, and when you mix the two, the oil divides into smaller bubbles of it above the water. This shows that water cannot dissolve lipids, although it is coined as a “universal solvent”. When adding detergent to water, it sinks to the bottom of the beaker. When mixing them together, the detergent dissolves in the water. This shows once again, that water dissolves most substances, except

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

Our hypothesis was partially correct, the property changing substances did have the weakest coherency with the lowest drop counts of 23(carbonated), and 14(soap), and pure water did have the strongest bond. What we also found was the the salt also dampened the liquid’s ability to hold onto a penny in large volumes, as all the different salts had a drop average of 24(28x2 & 16), five less than Tap water’s drop count (30). This led us to conclude that pure water has the strongest bond and that all foreign materials weaken the coherency of water. This evidence has led me to believe that similar substances are attracted and are more coherent towards themselves, in this case the water pieces get separated and generally less connected on a really small level due to the obstruction of foreign objects, this is why the different salts perform better than the huge air bubbles or the slippery properties of soap since the latter is more obstructive and the former dissolves with the water and blocks less. When studying a few other groups’ conclusions and data we did indeed find differences: some groups had differing data where a solution had better coherence than water itself which led to differing conclusions.

Density is the calculation or equation of mass divided by volume and it can be used to identify different substances. Density is always the same in one object or substance because density is a constant ratio. Objects have “lighter” densities will float while objects that are “denser” will

Many religions use water to purify and cleanse. In the Catholic religion, priests use water to baptize. In the Hindu religion, people use it to cleanse themselves before prayer. Water is often viewed as holy and sacred by these and many other religions, and is commonly associated with life and purity. However, Rudolfo Anaya in his book, Bless Me, Ultima, takes a completely different turn on this commonly used symbol.

Rene Descartes invented the Cartesian Diver, which is an object that floats but sinks when pressure is applied. Rene Descartes created a way to demonstrate the idea of buoyancy and the ideal gas law. The name of the Cartesian diver came from the inventor Rene Descartes. Some objects float in water because of the difference in density of the water. Water is much denser than air, which means when the eyedropper begins to suck in water, the density becomes greater then its overall surroundings.

Sometimes the relationship between two generations is very complicated. “My Father Is a Simple Man” by Luis Omar Salinas and “A secret Lost in the Water” by Roch Carrier explore these universal themes, the greatness of love together with the unavoidability of conflicts between two generations through the depiction of the speakers’ personal experience with their fathers. In “My Father Is a Simple Man”, the speaker expresses his love for his father deeply by highly complimenting that his father has sincere “kindness and patience” (Salinas 23) to take the speaker on “lifelong journey” (Salinas 9-10). In the end of the poem, the speaker firmly believes that he should “have learned” (Salinas 36) something from his father which states a manifestly

What significant physical properties of blood determine the shape of a blood drop in flight? A blood drop, which can be either a single drop or in large volumes, are held together by strong cohesive molecular forces that produces a surface tension within each drop and on the external surface. Surface tension are forces that pulls the surface molecule of liquid toward its interior, and decreases, as the force pulls the surface, causing the liquid to resist penetration. Gravity begins accelerating the drop downward, and the trajectory will take the drop to the floor or ground or whatever other object intervenes in its flight.

In this experiment, a virtual program designed to demonstrate the swimming of a virtual fish, was used. This program is called SWIMMY. SWIMMY was used in this experiment to determine the circuits that are used in the movement of an animal. This is done by presenting the neurons and the neural circuits in a body which can allow and show the movement of the fish’s tail virtually. The movement of the fish tail occurs by the activation of motor neurons.

if you put a thin layer of petroleum jelly on a glass surface, small water droplets could stick with the greasy surface and would not descend under the force of gravity. Glycerine is totally miscible and does not have that kind of effect on water droplets. Both petroleum jelly and glycerine appear like a slimy material,

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
