Procedure and dataBlock of wood |
Materials for all: Block of wood. Meter stick. Graduated Cylinder. Ruler. Caliper. 5 peices of paper.
First off we had to determine the length, height, and width of the wood. Using the vernier caliper, we determined them to be: L: 5.06 cm
W: 2.08 cm H: 5.1 cm |
|
We took 5 pieces of paper and stacked them, at which point we used the caliper and ruler to measure it's thickness (width).
W: (of 5 sheets) .2 mm |
The cylinder |
Next we took the caliper and measured the diameter as well as height of the cylinder.
D: 1.2 cm H: 10.8 cm. |
The room |
To measure the room, we used the meter stick and measured the height from the floor to the ceiling, and then took the length and width of the room.
L: 12.80 m W: 7.87 m H: 2.90 m |
Data analysis |
Ok, using all this data we can do some math work and find out the volume of the block of wood.
Volume of wood: 2.08 x 5.06 x 5.1= 53.68 cm^3 We can divide to find the thickness of a single piece of paper. Paper thickness: .2mm/5 sheets of paper= .08 mm We can also calculate the volume of the cylinder: (1.2/2)^2 x 3.14 x 10.8 = 12.21 cm^3. Finally, we can calculate the volume of the room. Room volume: 2.90 x 12.80 x 7.87= 292.13 m^3. |
in conclusion |
Basically the point of this exercise was to:
1) Re-familiarize ourselves with measurements and how to take them with the Vernier Caliper. 2) Understand and practice having a blog-format for a lab report. I would say that these goals were met with great success. |
