Title: Measuring Mass and Volume

Name: _____________________ Per: ___

Unit: Density 7.1.2

Introduction:

Mass and volume are two very important ways to determine how much of a substance we have. Mass describes how

much matter is in an object. Volume describes how much space something takes up. Mass is measured on a triple

beam balance and is reported using the metric unit known as ‘gram.’ One gram is about equal to the mass of a large

paper clip.

Background Information:

Mass (the measure of how much matter is in an object) is measured in two ways:

1) Triple beam balance.

2) Digital scale.

Steps:

When you find the mass of an object, first

measure it on the triple-beam balance.

2. Then check your answer on the digital scale.

3. Record your answer and include grams for your units.

Volume (the measure of how much space something takes up) is measured in three ways for solids:

1) For cubic or rectangular shapes, use the formula “length x width x height” with the unit in cubic

centimeters (cm

Materials: Ruler, calculator

Steps:

Use a ruler to measure the length, width and height.

Be VERY precise. Record measurements in cm.

2. Use the formula V = l • w • h and record your answer with cm

for units.

2) For irregularly shaped objects, use water displacement with the unit in milliliters (mL).

Materials: Lunch tray, cup w/ water, graduated cylinder

Steps:

Pour enough water from your cup into the graduated

cylinder to reach a height that will cover the sample. Read

and record the initial volume.

2. Slightly tilt the graduated cylinder and carefully place the

sample into the water. Avoid splashing.

3. Place the graduated cylinder upright on the table and get at eye-level to read the level of the water. If the

sample floats, use a pencil to gently push the top of the sample just under the surface

of the water (don’t submerge your pencil). Record the number of milliliters for this

final water level.

4. Find the amount of water displaced by subtracting the initial level of the water from

the final level. This volume equals the volume of the cylinder in cm

(we use cm

for solids

and mL for liquids).

5. Record this volume in the chart on the activity sheet.

6. Remove the sample by pouring the water back into your cup and taking the sample out of

your graduated cylinder.
