Pestle Analysis Lab Report
ABSTRACT, EXPERIMENT AND OBSERVATIONS:
ABSTRACT:
The objectives are to understand and apply the means to measure distance, mass, volume, density and time using different scientific tools and methods. Precision, Accuracy, etc. would be utilized from the past learned skills and applied to future labs while working on calculations.
EXPERIMENT:
Throughout physics(labs), measurements are determined with help of experimental data manipulation. In the lab it is detrimental to know how to measure length, mass, and time in accurate and precise manner.
MATERIALS: • 3 Box-like objects (block, thick book, shoebox, etc.)
• 2 Pencils or pens
• 1 Chair or step stool
• 5 Circular objects of different size (cups, plates, etc.)
• 1 Computer and …show more content…
Record all measurements in Data Table 2. Units should be in centimeters and recorded to the nearest half-millimeter as before.
4. Calculations:
a. Find the volume of the object using the three different sets of measurements. Remember, the volume of a rectangular box is: v = length × width × height. Show the units as cubic centimeters when recording the calculated volume in Data Table.
Exercise 3: Graphing Data and Determining π : In this exercise, you will choose circular objects and measure the diameter and circumference of these objects. Measurements will then be used to graph and calculate the slope. You will then compare the value of the slope to the true value of pi and calculate percent error.
1. Before beginning, set up a data table similar to the Data Table 5: Determination of π, in the Lab Report Assistant section.
2. Select five circular objects of different sizes, such as an AAA battery, a screw cap from a soft drink bottle, the cardboard center of a paper towel roll, cups of various sizes, or plates of various sizes.
3. Use the metric ruler or tape measure to measure the diameter D in centimeters of each object to two decimal points and record in Data Table …show more content…
What is the slope of the line? What does it represent? Record the slope of the line for each object in Data Table 5.
8. Calculate the percent error of this value obtained from the slope from the true value of π and record in Data Table 5.
** NOTE: Circumference is 2pir and diameter is 2r.
Exercise 4: Density Measurements
In this exercise, you will use different methods to calculate the density of a metal bolt. You will then compare the accuracy of these methods.
1. Before beginning, set up a data table like the Data Table 6: Density measurements, in the Lab Report Assistant section.
2. Find the mass of the bolt using a digital scale and then compare this value to the mass of water displaced by a bolt. Use the following steps:
a. Use the digital scale to find the mass in grams of the metal bolt. Record the mass next to “Mass using scale (Ms)” in Data Table 6.
b. Fill the graduated cylinder to exactly the 10-mL line with water. Tilt the graduated cylinder at a 45 to 60 degree angle and allow the bolt to slowly slide down the side of the cylinder until it rests at the bottom. Be careful not to allow any water to splash out of the graduated
