Essay about Lab 1-Measurement, Length, Mass, Volume, Density & Time

6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

1. What do you think would happen if you threw a block of Styrofoam™ into the water? The Styrofoam will float

Determine the volume of the magnet and metal bolt to +/- 0.1 mL using units and sig figs carefully. Measure the mass and calculate the density of the magnet and metal bolt using the correct significant figures and units. Show work for full credit. (2 points)

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.

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

3. Experiment: Use the Gizmo to find the carrying capacity with Ample, Moderate, and Little land. List the carrying capacities below.

I took the graduated cylinder and started filling it up with water until the bottom of the meniscus was to the the 100.0 mL mark with the assistance of a dropper pipet. I then took the 13 x 100 mm test tube and slowly poured the water from the graduated cylinder into the test tube until it was full to the top. I then poured the water in the test tube out into the sink and put the graduated cylinder on the counter so I can get an accurate measurement of the lower meniscus to record on my data table. I once again followed the same procedure again filling a second test tube with water from the graduated cylinder then setting it on a straight surface to get an accurate measure of the volume to

that were not correct and correct them, giving the data from your experiment that supports the corrections.

1. During gym class, four students decided to see if they could beat the norm of 45 sit‐ups in a minute. The first student did 64 sit‐ups, the second did 69, the third did 65, and the fourth did 67.

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

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

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.

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.

Another example of when measurements such as length, width, and volume would be important is in a situation where one is buying a fish tank. Depending on the number of fish you would like to buy, you will need a fish tank that has the capacity to hold a larger volume of water. However, you may also have a limited space that you can put your fish tank in, such as on a stand that may not be very long or wide. You would use the length and width of the location for the tank to determine the maximum size of the tank. You would also use the length, width, and height of the tank to determine its volume or water capacity, allowing you to adjust any dimensions depending on the amount of fish you would like to keep in the tank.
