4-PS3-3 - Ask questions and predict outcomes about the changes in energy that occur when objects collide.

Clarification Statement - Emphasis is on the change in the energy due to the change in speed, not on the forces, as objects interact.

Assessment Boundary - Assessment does not include quantitative measurements of energy.

4-PS3-3 - Ask questions and predict outcomes about the changes in energy that occur when objects collide.

Clarification Statement - Changes in energy can include a change in the object’s motion, position, and the generation of heat and/or sound.

Assessment Boundary - Analysis of forces or quantitative measurements of energy are not expected in state assessment.
