BIG IDEAS
P4.2 Energy Transformations Energy is often transformed from one form to another. The amount of energy before a transformation is equal to the amount of energy after the transformation. In most energy transformations, some energy is converted to thermal energy. |
Standards Covered:
P4.2A Account for and represent energy transfer and transformation in complex processes (interactions). P4.2B Name devices that transform specific types of energy into other types (e.g., a device that transforms electricity into motion). P4.2C Explain how energy is conserved in common systems (e.g., light incident on a transparent material, light incident on a leaf, mechanical energy in a collision). P4.2D Explain why all the stored energy in gasoline does not transform to mechanical energy of a vehicle. |
9 Pretest and DifferentiationIf you score a 90% or above on this pretest on your first attempt you will not need to complete any of the practice for this unit and an accelerated assignment will be provided. The pretest is not open internet or buddy or book. This pretest will be timed and may only be completed in class.

PRACTICE
Voice Thread or other (20-30 min) Create a voice thread reviewing the energy transfer in any example in the PhET simulation below. Use the video example as a guide as to what you will create. Be sure to include: a. all energy types identified in your voice or text b. all transfer of energy (change of energy from one form to anther) identified in your voice or text c. digitally share with teacher upon completion
