MS-PS3-6 ENERGY

OKLAHOMA ACADEMIC STANDARD FOR SCIENCE:
MS-PS3-6 ENERGY
6TH GRADE
OBJECTIVE:
Students who demonstrate understanding will be able to construct, use and present arguments to support the claim
that when the kinetic energy of an object changes, energy is transferred to or from the object.
CORE IDEAS: CONSERVATION OF ENERGY AND ENERGY TRANSFER
When the Kinetic Energy of an object changes, there is inevitably some other change in energy at the same time.
CLARIFICATION STATEMENT:
Examples of empirical evidence used in arguments could include an inventory or other representation of the energy
before and after the transfer in the form of temperature changes or motion of an object.
ASSESSMENT BOUNDARY:
Assessment does not include calculations of energy.
MATERIALS REQUIRED:
•
•
•
•
•
Gravitate Kit
o 2 rubber hoses
o Braces
o Legs
Measuring Tape
Balls of varying sizes and weights
Scale (for weighing balls)
Stopwatch
PREPARATION:
1. Set up the track.
2. Ask the students what data they want to collect to support the statement that, “when the Kinetic Energy
(motion energy) of an object changes, there is inevitably some other change in energy at the same time.”
3. Record base measurements:
a. Measure and record the track length L. _____m
b. Measure and record the track height H. _____m
c. Measure and record the mass of the ball(s). _____kg

4. Create a data table to record their data elements (or use the table on page 3). For example:
a. Record forms of energy observed. (Kinetic, Potential, etc.)
b. Record evidence of energy transfer. (sound, change in motion, change in speed, etc.)
c. What are your deductions/conclusions based on this evidence? (friction, heat, motion transfer, etc.)
PROCEDURE:
Note: Guide the students through the first experiment; then let them conduct experiments.
Ask the students to write down each step of each experiment.
Conduct the experiment(s).
1. Record the weight of 2 balls.
2. Place one ball at the top of the track and the other at the bottom of the hill.
3. Start the stopwatch as you release the ball at the top of the track. If the top of the track is flat, you may need to
give it a gentle push.
4. Ask the students to list any evidence they observe that energy was transferred.
5. Ask the students to tell you what deductions or conclusions they can draw from this evidence.
6. Repeat steps 1 through 6 allowing the students to conduct the experiment.
Assess: Ask questions to help the students identify the various forms of energy and evidence of energy transfer.
