Energy Transfer Demo- Diagram

  1. Draw a Diagram of what you saw in the demo.

Draw all of these items:

  • Pickle
  • Power socket
  • Cord
  • Nails

Label all of these:

  • Kinetic Energy (KE)
  • Potential Energy (PE)
  • Electrical Energy
  • Heat Energy
  • Light Energy

in some places, you might have 2 labels!

2) Use the highlighters at your table to color code your diagram.

Pink = Potential Energy Purple (both colors) = TRANSFER of energy

Blue = Kinetic Energy

Two Types of Energy Transfer

Energy can be transferred:

  • From one object to another

AND

  • From one type (form) of energy to another

Include 1 example of each type of energy transfer that you saw in the pickle demo

Energy Transfer- Why does it happen?

Table Talk:

The video said:

“We know that the amount of energy in the universe always stays the same”.

Explain how this could be possible, using what you know about Energy Transfer.

Law of Conservation of Energy

Energy cannot be created or destroyed, only transferred from object to object or form to form.

Extension:

Think of an experiment that could prove the Law of Conservation of Energy using Energy Transfer as evidence.
