What I Can Do
PERFORMANCE TASK: 1 Think, Therefore I Am...An Engineer!
Performance Content: Create a device that shows conservation of mechanical energy and
answer the questions that follow on the activity you have chosen.
(A) DIY MINIATURE SWING
Objective: To design and build your own miniature swing that will demonstrate the
relationships between forces and energy to motion.
Materials:
Set of Popsicle stick and chopstick (banana cue stick)
• String
Stick gluel Glue Gun
Things to do:
1. Name your swing. (5 pts)
2. Draw the blueprint on a bond paper (10 pts)
3. Include the following in the blueprint (drawing):
Highest Potential Energy (Hi PE)
- Lowest Potential Energy (Lo PE)
Highest Kinetic Energy (Hi KE)
- Lowest Kinetic Energy (Lo KE)
Demonstration:
1. State the name of your model.
2. Identify the components of the amusement ride.
3. Identify where PE and KE are maximum or minimum.
4. Define total mechanical energy,
5. Derive a conclusion that the total mechanical energy of the system remains the same.
