NGSS MS-PS3-5
The Standard
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.

What This Standard Means
What Students Need to Do
- Students compare an object’s motion before and after an interaction and decide whether its kinetic energy increased or decreased. They use observations, such as speed or temperature changes, to argue that energy moved into or out of the object.
What Mastery Looks Like
- Students can identify the direction of energy transfer from a before-and-after motion record. They support the claim with specific evidence and explain why it shows a kinetic energy change, without calculating energy.
Common Misconceptions
- Students often say energy disappears when an object slows or appears from nowhere when it speeds up. They may confuse speed with force or assume a direction change at constant speed always changes kinetic energy. They may also miss that warmer brakes or surfaces provide evidence of energy transfer.
How to Assess It
- Exit ticket: A toy car rolls onto carpet and slows. State whether energy moved into or out of the car, then cite one observable piece of evidence.

Ways to Teach It
Roll a marble into a stationary cup, record both objects’ motion before and after, then draw arrows showing the direction of energy transfer.
Discuss this prompt: A soccer ball stops in mud; where did its kinetic energy go, and what evidence supports your answer?
Sort scenario cards into energy transferred in, energy transferred out, or no kinetic energy change, then justify each choice with motion evidence.
Examine bicycle braking, then explain how slower wheel motion and warmer brake pads show energy transferring from the bicycle.
