QUICK LAB
OBJECTIVE
Mass and Weight
In this lab, you will compare the mass and weight of five
different objects using a balance and a spring scale.
• Describe the
relationship between
mass and weight.
MATERIALS
PROCEDURE
1. Using a triple-beam or electronic balance, measure the
mass of five small objects. Record the masses in grams
in the chart below.
2. Using a spring scale, find the weight of the same five
objects. Record the weights in consistent units.
Mass (g)
(x – axis)
For each group
• balance, triple
beam or
electronic
• graph paper
• small objects (5)
• spring scale
For each student
• safety goggles
Weight (N)
Toy Truck
Block of Wood
Scissors
Nail
Spoon
3. On a piece of graph paper (on back), make a graph of weight versus
mass using your five objects.
a. Label X and Y axis with appropriate title
b. Plot data points
c. Using the ruler, create line of best fit to show the general
trend of your data
d. Add a title (already done for you)
(y-axis)

4. In the space below, write a sentence that describes the relationship between
weight and mass. (look at the general trend of your data)

5. The objects were not moving when you measured their weights (using the
spring scale). What was balancing the force of gravity pulling them downward?
