analyzes information from
experiments, simulations,
and multimedia with that
gained from reading text
on the same topic. In
addition, the student’s
prior knowledge is used to
present their viewpoint.

information from
experiments, simulations,
and multimedia with that
gained from reading text
on the same topic. Student
shows some
understanding of the topic.
Developing (16-15 points)
Student partially analyzes
information from
experiments, simulations,
and multimedia with that
gained from reading text
on the same topic. Student
shows little understanding
of the topic.
Why do objects with more mass weigh more than objects with less mass? All
objects have weight on Earth because their mass is affected by Earth’s
gravitational force. Because the mass of an object on Earth is constant, the
relationship between the mass of an object and its weight is also constant. You
will measure the mass and weight of several objects to verify the relationship
between mass and weight on the surface of Earth.
MATERIALS
• double pan balance (metric)
• spring scale (force meter)
• classroom objects
• Ziploc bag with a hole punched

PROCEDURE
1.Use the table below to record your data.
Object
Mass and Weight Measurements
Mass (g)
Weight (N)
Stopwatch
Toy car
Wooden sphere
Calculator
Steel sphere
D size battery
2.Using the metric balance, find the mass of the six objects listed in the data
table. Record the mass for each item, using the appropriate label (g).
3. Using the spring scale, find the weight of each object. Record the weight for
each item, using the appropriate label (N). You may need to put some objects
in the Ziploc bag and hang it on the spring scale to measure the weight.
4. Identify the variables for this experiment:
Independent: ______________________________________________________
Dependent: _______________________________________________________

ANALYZE THE RESULTS
1.Using your data and the graph below, construct a graph of weight (y-axis)
versus mass (x-axis). Draw a line that best fits all your data points.

2. Does the graph confirm the relationship between mass and weight on Earth?
Explain your answer using evidence from the graph and the textbook .

Student Set-Up–1
Concept Level–2
Clean Up–1
MATERIALS
The materials listed are for each group of 2–3 students. A set of metric masses
may be used as objects, but at least one random object should be included. Objects
must be measurable with the spring scales and metric balances.
SAFETY CAUTION
Remind students to review all safety cautions and icons before beginning this lab
activity.
PREPARATION NOTES
If metric masses are used, put a small piece of opaque tape over the stamped value
for mass. Ensure all objects are easily picked up with the spring scales. Use string
to create a “handle.” Choose at least five objects for each group.
