Science Fair Question : Can You Accurately Measure Pi Through Scientific Experiments?

5. Restate your predictions that were correct and give the data from your experiment that supports them. Restate your predictions that were not correct and correct them, giving the data from your experiment that supports the correction.

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

There are several sources of error to this experiment due to random and systematic errors. The only source of random error was the measurement that we took through the graduated cylinder which was only accurate to the nearest 1%. We took the largest error from this one percent, which was +/- 3. The largest relative error this yielded was only 3%, so this did not affect how precise this experiment was too much. We can still make this more precise by making the masses of the water larger. For example if we started the masses at 300mL and went up by 50mL, the largest error this would yield would be 2% due to the largest error being +/- 5. This would cause smaller errors in the amount of water.

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.

Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.

Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this.

Which of the following conclusions is most valid, given the results of experiment 1? 6-8.2

Predict what will happen and run the simulator three times, recording your data for each run. Answer the following:

The experiment is repeated twice and an average is obtained. This ensures the consistency of the measurement as the reading is triplicated, thus reducing anomalies. It can be seen that the reading obtained were around the same value. This proves that the results are reliable.

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.

All of the tests were fair enough. Our first experiment was ⅓ (667 milliliters) and that test went very well. Our second experiment was ½ (1000 milliliters),⅓ (667 milliliters), and ¼ (500 milliliters). We tested all three bottle and it came down to two water amounts which were ½ (1000 milliliters) and ⅓ (667 milliliters). We used a mountain dew round cylinder bottle in all of our tests because it was the best type of bottle more than the rest of the bottle and we did a lot of research and that bottle was the most common bottle to build a bottle rocket . We filmed videos on both water amount and they both went really high except there was a .2 second difference between the two amounts. Overall the group decided that ⅓ was the highest since it beat ½ by .2 seconds. Some Manipulated variables are The water

Pi has been used for the past 250 years. The first zero in pi comes after the first 31 digits. Archimides was the first person to study pi in the ancient times.

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me
