Measurments Lab
PURPOSE: The purpose of this lab activity is to practice:
- using a meter stick, a Vernier caliper, and a micrometer
- recording measurements and estimating their uncertainty
- calculating using significant digits.
- choosing an appropriate measuring device.
EQUIPMENT:
meter stick
Vernier Caliper
Wood Block
metric ruler
micrometer
cylinder
meter stick
Vernier Caliper
Wood Block
metric ruler
micrometer
cylinder
PROCEDURE:
Variables:
Independent - measuring tools
Dependent - height, width, length and/or diameter.
- The independent variables are the tools used, which will help give the most appropriate measurement. The proper independent variable will be chosen to measure the dimensions of various objects.
Length - 76.1 mm
Width - 74.1 mm
Height - 11.6 mm
- Multiply (length x width x height)
76.1 x 74.1 x 11.6 = 65412.5mm³ or 6.54 x 10³ mm³
2. Find the volume of a cylinder.
- Measure radius and height of cylinder using the Vernier Caliper and metric ruler respectively
Diameter - 10.1 mm ---> Radius - 5.05mm
Height - 100.65 mm
- Multiply πr²h
3.14 x 5.05² x 100.65 = 8.06 x 10³ mm³
3. Find the thickness of a page of paper in your text book.
- Measure thickness using micrometer
Thickness = .04 mm
4. Find the volume of the room
-Measure height, length, and width of the room using a meter stick
Length - 9. .3 m
Width - 7. 6 m
Height - 2 . 7 m
- Multiply (length x width x height)
9. 3 x 7. 6 x 2 . 7 = 190.836³
Conclusion
The purpose of the lab was to measure different objects that we were given by using the metric measurments and using the best tool of the tools given in order to find the unkown variable that we were given. The micrometer was the best tool to measure the thickness of a piece of paper, but the meter stick was the best tool to use for measuring the room. All the measurments that were obtained by using the tools were accurate but not perfect in measurement because of human error and slight inaccuracy in the tools.
