LAB #3 – Measurement: Volume
Introduction
Volume is the amount of space
occupied by matter - solid, liquid, or gas. Objects occupy space within a
gas, liquid or even within a solid. We
measure volume in units of mL for liquids and cm3 for solids.
Problem
●
A: How can we find the volume of a
rectangular object?
●
B: How can we find the volume of an
irregularly shaped object?
Hypothesis
A:
|
B.
|
Materials
A: Rectangular
shaped objects
B: Irregular
shaped objects
A: Ruler
B: Graduated
cylinder
Procedure A
1) Use a metric ruler to measure the
dimensions of your rectangular objects; measure to the nearest tenth (0.1) cm.
2) Calculate the volume in cm3 of your rectangular object by multiplying the length (cm) times the width (cm) times the height (cm). V = L x W x H
3) Record your measurements in the data table.
2) Calculate the volume in cm3 of your rectangular object by multiplying the length (cm) times the width (cm) times the height (cm). V = L x W x H
3) Record your measurements in the data table.

Procedure B
Use a graduated cylinder to measure
the volume of an irregular shaped solid.
1. Fill the graduated cylinder to 50
mL or 25 mL (depending on the size of graduated cylinder you have) and record
this into your notebook.
2. Carefully drop the object in on
an angle.
3. Subtract your initial volume from
the new water level.
Results
1. New Volume ------------à _____mL
Initial Volume ------------à _____mL
Volume of irregularly shaped object:
_______mL
2. New Volume ------------à _____mL
Initial Volume ------------à _____mL
Volume of irregularly shaped object:
_______mL
Analysis
1) What is volume?
2) A. Why would a scientist measure volume? B. Give two examples of a situation in which
a scientist would measure the volume of a liquid. C. Give two examples of a situation in which
a scientist would measure the volume of a solid.
3) Where do you encounter volume on a day to day basis?
4) How does understanding volume assist you in your life?
5) If you wanted to measure the volume of an irregular shaped
object, what is the name of the device you would use?
6) One side of a cube is 5 cm long; what is its volume? (Don’t
forget units!)
7) How are cubic centimeters and milliliters related?
Conclusion
Ch. 1 Test Tips and Hints
A scientific _________ is an explanation of a
pattern observed in the natural world, whereas a scientific ________ is a rule
that describes a pattern that is repeated in nature.
