1. What types of potential energy does
the spring possess?
TYPES OF
ENERGY FOR A
SPRING
CONTINUED
• Both elastic and gravitational.
2. How does the potential energy change
as the kinetic energy increases?
• The potential energy decreases.
3. How does the potential energy change as
the kinetic energy decreases?
• The potential energy increases.
4. What causes a change in the amount of gravitational
potential energy?
• The position of
TYPES OF
ENERGY FOR A
SPRING
CONTINUED
the spring, the higher it is, the
greater the gravitational potential energy.
5. What causes a change in the amount of elastic
potential energy?
• The shape of
the spring, when it is compressed it has
the greatest elastic potential energy.
6. What happens to the energy as the spring bounces
off the ground and then comes back down again?
• The energy continually transforms into a different
type.
7. What is happening to the spring when it has the
greatest kinetic energy?
TYPES OF
ENERGY FOR A
SPRING
CONTINUED
• It is moving fast.
8. What has the energy transformed into when the
spring finally comes to rest?
• Energy of heat, as it moved through the air there
was friction and the energy caused the air to
heat up, thus transferring the energy to a
different system resulting in the spring finally
coming to rest
COMIC STRIP
• Every group will get a comic strip paper and will draw a multipanel (3-5) comic strip of an acrobat performing on a pole (stick
figures). I will replay the video
• Label the following on the comic strip (can use labels multiple
times)
•
•
•
•
•
•
Elastic potential energy
Gravitational potential energy
High kinetic energy
Low kinetic energy
High potential energy
Low potential energy

Carousel to visit the cartoon strips of other student groups
Leave a sticky note (or write on a piece of loose-leaf paper) for each
group asking one question about their LABELS (not the drawing)
Afterwards, return to your own cartoon and make changes to the labels
based on your observations of others and questions that were asked
You will individually (Level 0) revise definition for kinetic energy, revise
level of confidence in your understanding (1-4, 1 being no confidence, 4
being totally confidence)
You will individually (Level 0) revise definition for potential energy, revise
level of confidence in their understanding (1-4, 1 being no confidence, 4
being totally confidence)
COMIC STRIP THINK/PAIR/SHARE
1.) Where was elastic potential energy evident with the acrobatic act?
•
The pole had elastic potential energy
2.) On what property was the amount of elastic potential energy based?
•
The shape of the pole, the more bent it is, the greater the amount of elastic
potential energy.
3.) Where was gravitational potential energy evident with the acrobatic act?
•
When the acrobat was off the ground, she had gravitational potential energy
COMIC STRIP THINK/PAIR/SHARE
4.) What variable impacts the amount of gravitational potential energy?
• The position, the higher off the floor, the greater the gravitational potential
energy
5.) Where was kinetic energy evident with the acrobatic act?
• There was kinetic energy evident when the acrobat was moving
6.) What property impacts the amount of kinetic energy?
• The greater the speed, the greater the amount of kinetic energy.
7.) How are the amount of kinetic energy and the amount of potential energy
related to one another?
• When one is high, the other is low.
LAW OF CONSERVATION OF ENERGY
• How can the Law of Conservation of Energy
be defined using this observation?
• Energy is not created nor destroyed; it
is transformed from one form to
another.
•

ANTICIPATION GUIDE
• On the right-hand side that says “After
Lesson” you will answer the same
True/False Questions.
• If you don’t need to correct your answer,
then just put the same answer down. But
every box should be filled out.
• When you are done you will tell your
shoulder partner which answers you
changed or didn’t change and why.
TYPES OF FORCES
JANUARY 15TH TO JANUARY 17TH
FORCE CHALLENGE
Write your prediction how you could use forces to get the ball into the cup
without touching the ball.
HOT QUESTIONS
• What force(s) were at work?
• How were the forces similar?
• How were they different?
TYPES OF FORCES
https://www.youtube.com/watch?v=STQRUzalH2M
EXPLORE TYPES OF FORCES
• Take a sheet of paper and divide it into 3 sections
• In each write one of the following sentences:
• How can objects be moved?
• Is there force on an object that is not moving?
• How can objects be moved without touching them?
• With your group make a claim related to one of the problem statements
• Hang your problem around the room
• Individually go to each paper and write an observation that you made that
could serve as evidence to support the claim
GROUP DISCUSS
•
What characteristic do gravitational, magnetic, and electrical forces have in common?
•
In what ways do gravitational, magnetic, and electrical forces differ?
•
Are there forces acting on objects that are holding still? Explain.
•
What are some other forces?
•
Which can be categorized as non-contact forces and which as contact forces?
•
What does “non-contact force” mean?
•
In what ways are electrical forces similar to magnetic forces?
“TEN FREAKY FORCES OF NATURE”
• Write down places where a force caused motion (4 examples)
• Think back to the places where a force cause motion, write down what type of
force caused the push or pull.
• List the contact and non-contact forces in the story
