How Length Affects Pitch Lab Report

    One possible source of error that can affect the results was that a mercury thermometer was used instead of an electronic one. The use of a mercury

Look at the calibration marks on your ruler to determine the degree of uncertainty and number of significant figures that can be made when measuring with a ruler.

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.

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.

There are two main errors that could happen in this lab. The first being human error when weighing the elements. This would result in more reactants which would cause more products and a misreading

This lab is all about measurements and recording them properly. The lab first introduces to use the measurement of centimeters, millimeters, and meters to measure different household objects in our everyday life. We were given the task to use the provided ruler and measure a CD, key, spoon, and a fork in centimeters and then convert our findings to give us the appropriate units of millimeters and meters for each object required in the exercise.

The purpose of this lab was to find out how the amount of time that has elapsed affect the position of the car away from the point of origin. Our hypothesis was if the time elapsed is longer, then the car is going to be further away from the point of origin. In this lab the independent variable-what you are changing is time. The dependent variable-what you are measuring is how far the car is from the point of origin after a certain amount of time (3 seconds, 6 seconds, and 9 seconds). The controls-things that stay the same throughout the whole lab is the car we used, the meter stick that we measured in centimeters with, and the 40 centimeters of tape that we used to mark the position of the car. Materials we used was a car, 40 centimeters of

The purpose of these experiments was to familiarize one’s self with laboratory equipment as well as becoming competent with different types of units as well as different methods of measurements.

The subject stands on the platform. The platform becomes unstable and the subject sees a square box in the monitor that is placed before them. Then the subject needs to shift one’s weight toward the direction of the box so the cursor in the box moves and get inside of the box and hold for 2 sec. Then repeat the process and wait for the next box to appear. The maximum time allowed is 300 sec.

On a website I found that people were testing if the size of the ball affected the speed(Brooks). But through my thorough search I didn’t find any experiments with people testing anything with the relations of music like my experiment. I was pretty amazed because you would think that there would have been something because it is two large topics in one. Music and Baseball.

To gather our information, we set up a pendulum and raised its height to 70 cm. In the wake of doing this we joined the string to the highest point of the pendulum and

Biltmore Stick. The Biltmore stick is a calibrated 25-inch scale stick used to help determine the volume or scale of standing trees. It is held horizontally against the tree 4.5' above the highest ground level of the tree, 25" from the eye. The left side or starting end of the stick is held at the edge of the tree and the size is read from the stick at the other edge. This will give the BHD of the tree. The number of 16' logs is determined by pacing 66 feet from the tree and holding the stick vertically 25" from the eye with the opposite end at cut off stump height.

Increase the length of string by about 15cm and measure the total length of the string. Record this length in the data table. Repeat this step along with steps 5-7 nine more times.

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.
