Introduction
A student was running an experiment. She laid out all her materials on a table. The materials she needed to complete this experiment was two containers, table salt, a tablespoon, tap water, and two fresh eggs. One of the containers was filled with 1 ½ milliliters of water and the other container was also filled with 1 ½ milliliters of water but 6 tablespoons of salt added to it. The container with salt was stirred until the salt has completely dissolved. Then one egg was placed in the container that had 1 ½ milliliters of water and the egg immediately sank to the bottom of the container. Then another egg was placed in the container with 1 ½ milliliters of water and 6 table

Archimedes wanted to melt the gold material into a known volume and weigh it, thus determining the density. But the king would not allow this. So Archimedes thought about this for some time, until one day while bathing, he noticed the water level increased as he entered the tub, proportionally to his volume. This meant that he could put the difficult-to-measure crown in water, and instantly know the volume of the crown by measuring the displacement of water. At this point, Archimedes leapt up from the tub and ran through the streets shouting "Eureka! Eureka!" What Archimedes came up with was a relationship between the volume of a solid and the volume of a fluid, which directly relates through the density equation, to a relationship between the density of a solid and a fluid, and the mass of a solid and a fluid. He also determined that the buoyant force, the mass of an object out of the fluid minus the mass of the object in the fluid, is equal to the weight of liquid displaced by the object. Archimedes determined that by measuring the weight of the water increase when the wreath was submerged, he was actually measuring the buoyant force acting on the wreath. And from this, he could divide by the density of water, and find the volume of the crown.” (AUVSI
3. The beaker was filled with water and the metal was placed in the water.
Thorough analysis of the graph displayed enough evidence suggesting that an increase in substrate concentration will increase the height of bubbles until it reaches the optimum amount of substrate concentration, resulting in a plateau in the graphs (figure 2). Hence; supported the hypothesis.
To start the lab, we got an egg and placed it in different substances to see how the egg would react to the substances. The first day we weighed the egg before putting it in a cup of vinegar, the egg weighed 55.47 grams, we left the egg here for approximately forty-eight hours. The second day, the egg was still in the vinegar. The third day we moved it into the corn syrup where it stayed until the next morning, the egg weighed 76.66 grams.
Archimedes principle says that the magnitude of the buoyant force always equals the weight of the fluid displaced by the object. This buoyant force always acts upward through the point that was the center of gravity of the displaced fluid. In the case of floating objects the buoyant force is equal to the force of gravity on the object. Knowing that the change in pressure is equal to the Buoyant force per unit area (ΔP = B/A) we see that B = (ΔP)A and ΔP = ρgH where ρ is the density of the fluid g is the acceleration due to gravity and H is the height of the fluid displaced.

According to the graph on amylase activity at various enzyme concentration (graph 1), the increase of enzyme dilution results in a slower decrease of amylose percentage. Looking at the graph, the amylose percentage decreases at a fast rate with the undiluted enzyme. However, the enzyme dilution with a concentration of 1:3 decreased at a slow rate over time. Additionally, the higher the enzyme dilution, the higher the amylose percentage. For example, in the graph it can be seen that the enzyme dilution with a 1:9 concentration increased over time. However, there is a drastic increase after four minutes, but this is most likely a result of the error that was encountered during the experiment. The undiluted enzyme and the enzyme dilution had a low amylose percentage because there was high enzyme activity. Also, there was an increase in amylose percentage with the enzyme dilution with a 1: 9 concentrations because there was low enzyme activity.
The experiment is aimed at giving a better understatement of osmosis process and the different conditions in which osmosis occurs.
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
The materials I need for this experiment are table salt, Epsom salt, kosher salt, sea salt, fifteen clear cups, ice cubes, and a stop watch.
that yields no solution and conscious thinking will not help you." No matter how much thinking you do if you are stuck thinking about it for long periods of time will not help you. The real answer will come to you when you think you are not thinking. By taking your mind off the bigger picture you will discover the answer while doing a task that is unrelated to the subject. This is what made Asimov develope the Wureka Phenomenon. Asimov further explained this by giving the reader multiple examples one of them being the crown made for Hieron II. The king was afraid that he had been tricked and that all of the gold he had given to the goldsmith hadn't all been used in his crown and substituted with an inferior metal, copper that was much less valuable. Archimedes, a Greek scientist and philosopher, was called in on the problem. At the time the only way to measure volume was to completely destroy the crown but the king would not allow that. Archimedes pondered how he would change the way to measure volume and got nowhere. He went to the public baths and noticed how water splashes out when he gets in the bath. As the water spilled out he discovered the modern use of finding volume in irregular objects such as a crown.
NOTE: The stirring rod was not used in the First and Second experiments, as it was not available. A substitute we used the thermometer.
After Galileo found out the moon wasn't flat, he began mounting a body of evidence that supported Copernican theory and contradicted Aristotle and Church doctrine. In 1612, he published his Discourse on Bodies in Water, refuting the Aristotelian explanation of why objects float in water, saying that it wasn’t because of their flat shape, but instead the weight of the object in relation to the water it displaced.
To test this, we set up two experiments. The first experiment we set up had three cups. In each cup a potato slice and a different liquid was put in. In the first cup was filled with distilled water. The second cup was filled with salt water and the third was left empty.
Archimedes was a Greek mathematician and scientist. He was born in Syracuse, Sicily in the year 287 B.C. He was educated in Alexandria, Egypt. Due to the lack of information about Greek mathematics, many Greek mathematicians and their works are hardly known. Archimedes is the exception. Archimedes was very preoccupied with mathematics. For instance, he often forgot to eat and bathe because of his always wanted to solve problems.
...5 when he was killed. When the Roman general found out this distressed news, it is said that he ordered Archimedes to be buried with honors. “A sphere carved within a cylinder covers the tomb of Archimedes. This is based on a remarkable invention made by Archimedes proving that the sphere has two thirds of the volume and surface area of the cylinder.” Because of this, it is very obvious that Archimedes was proud of his discovery about the ratio of the sphere and the cylinder.
