Evaluate the scenarios below, each of which demonstrate the transfer of kinetic energy.

Scenario 1: Thermometer

Scenario 2: Guitar Strings





The red liquid in the thermometer moves up and down the tube.

The guitar strings vibrate once the first was strummed.


Select one scenario and use it to support the following claim:


“When kinetic energy of an object changes, energy is transferred to or from the object.”


When constructing your argument to support the above claim, be sure to:

use necessary and sufficient evidence.
state the flow of kinetic energy.
use scientific reasoning to describe and explain the changes in observable features before and after the interaction (transfer of kinetic energy).
