Physics Lab Report Sample

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.

The law of conservation of mass states that matter can be changed from one form into another, mixtures can be separated or made, and or substances can be decomposed, but the total amount of mass remains constant. Taking this law from a different view we can state that the total mass of the universe remains constant. Whenever matter undergoes change the total mass of the products will be the same as the total mass of the reactants. For example, in this experiment sodium hydroxide and copper sulfate, the reactants have a total mass of 21.4 grams. The total mass of the products, copper hydroxide and sodium sulfate, was 21.13 grams. The 0.27 grams was a result of the solution staying on the thermometer that was used to measure the temperature. This law was formulated in the end of the 18th Century. It marked the beginning of modern history.

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?

Students will carefully observe acts of aggression and prosocial behavior on television, report their observations, and analyze their data to draw conclusions.

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

When you are doing the displacement method there can be an error on how much volume of water you accurately pour in.

This science fair project will test which antacids are most potent in neutralizing lemon juice. When an acid and a base combine the base will neutralizing the acid in a chemical reaction; this is how antacids work as well. Antacids are substances that will neutralize stomach acidity which in return relieves heartburn, indigestion, or stomach pain.

From the first test, which had the dummies sitting upright, and the data was: 41ft/sec, 54 milisec collision time, and 21g-force exerted on the

I will be doing my science fair project on what ingredient will best activate a package of dry yeast. Dry yeast was developed by Fleischmann's company during WW11, so that people in the army did not have to get their yeast refrigerated, while still being able to easily make bread. Activating means to cause an act or function. Activating dry yeast makes the yeast makes it thick, bubbly, and foamy. It will be an off white in color and sometimes appear to be more of a light brown. Yeast is single-celled fungi. There are roughly over 600 species of yeast that we know of. Many of which can be distributed greatly in nature. Where exactly can we get yeast? This may be a common question one may have about yeast. Yeast can be exudates in plants. This includes cacti and the sap of the plants. Also, yeast can be found in the skins of fruits like grapes, apples, and peaches. You may also get yeast from the skin of berries.

This experiment involved the work of two people, with one person dropping the ball, while the other person recorded the experiment allowing for a display of data. Firstly, place one ball on the top pan balance to find the mass of the ball, repeating for each ball. This is to ensure that each ball has a different weight, without being too similar. Make sure to choose three completely different balls. For example, a golf ball, tennis ball and basketball.

This review of literature discuss the main terms,and ideas related to the experiment conducted,and seeks an explanation on why it happen. The topic will cover kinetic energy, gravity,velocity, and force of impact. Even if we know the process of conservation of energy to an object that is falling allowing us to predict its impact velocity, as well as the kinetic energy. However we cannot predict the impact force without knowing how far it will travel after impact.

“The Weighing of the Scales” is about twins who have been different from one another since birth. The short story focuses mainly on the older Jaclyn, between her and her sister’s twenty-ninth and thirtieth birthdays. The story depicts Jaclyn losing her job, her house, then asking to move back in with her mother and sister. After these events occur and Jaclyn has been moved in for a few days, Lillian confronts her about knowing the truth about her losing her job. Jaclyn begs Lillian not to tell their mother who has just pulled into the
