Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

Thales was the next person in the chronological history of philosophy. He was an astronomer and a

the test tube. On the temperature graph, the highest point was at 27ºC, which means that

Used to see if the temperature of the water is at 37oc – 40oc and if

22. Pushing the stopper to make sure it is firmly attached to the mouth of the syringe, press the plunger inward.

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

2. Read and record the temperature of the gas using the thermometer attached to the container.

* By using the dropper and measuring cylinder, an amount of 5ml milk was placed in the test tube

My calculated volume values were found by using the Charles’ Law formula: V1/T1=V2/T2. My Trial A values (20 mL and 293.15 K) were the V1 and T1 values. The temperatures measured in Trials B, C, D, and E were the T2 values. The quantitative relationship between the volume and the absolute temperature of a gas is summarized in Charles’ Law. This law states that at constant pressure, the volume of a particular sample of gas is directly proportional to the absolute temperature. In other words, there is a direct relationship between temperature and the volume of gas. In an actual laboratory, it must be ensured that the hot water is below 50ºC. If it is not, the sealed syringe will soften and it could explode.

In this gummy bear lab, the goal was to see the movement of water in cells depending on the concentration of solutes in the environment. The control group was the type of water used. The research question for this experiment was, how does concentration of solute in the environment affect water movement in cells? The hypothesis thought of for this question was that the salt water would enlarge the gummy bear the most. The distilled water would not enlarge the gummy bear as much as the salt water.

13. You will need to be able to convert many different units to ensure you can keep up with documentation errors successfully.

Galileo(1564-1642) Made the telescope better and he used the telescope to observe planets, and he proves kepler’s theory, saw the imperfection of planets, and saw a storm on a planet also saw craters.

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

Aristotle was one of the most important western philosophers. He was a student of Plato and the teacher of Alexander the Great. He wrote on many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, biology, and zoology. I found that his biggest impacts on modern society were in the subject areas of ethics, and zoology.

The earliest philosopher/scientist are called Pre-Socratic philosophers. They came before the great philosopher Socrates. Thales is to be the first. Thales is referred to as the father or founder of philosophophy/science he lived in the sixth century BCE. Thales began to search for the unity principle, which is the ground of all things.
