I Title: Measurements

II Purpose: Practice in Measurements

III Equipment: any typical textbook, meter stick, metric ruler, vernier

IV Procedure:
1. Measure the length, width, and height of the book. Record.
2. Calculate the surface area (approximately) of this 3-D object. Record.
3. Calculate the volume of the book. Record.
4. Use the vernier to estimate the thickness of a page. Record.
5. Think of an alternative way to determine the thickness of a page. Explain your method, and Record.

V Data
1. The length x width x height of object, in cm: _______ x _______ x ________

2. The surface area of the object: ___________ cm2.

3. Volume of the object: ___________cm3.

4. Thickness of one sheet in the book ___________ cm.

5.Alternate method to find thickness (explain).

6.Thickness of one sheet using this method: ______________cm.

VI Results: In this section, explain how successful you were at achieving the Purpose.

VII Error
A. Qualitative – sources of error
1. Personal – what things did you or your partner(s) do to screw things up, if anything at all?
2. Systematic – what was wrong with the equipment that caused the lab to go “bad”, or, what external factors (hurricane, earthquake, etc) contributed to difficulties in this lab?
3. Random – there are always random errors, unless you do this lab exercise 5 times and take an average
B. Quantitative – NA

VIII Questions
1. What is a vernier caliper?
2. What is a micrometer caliper?
