Listed below are the Disciplinary Core Ideas (DCI) for Physical Science and bullet points for their specific grade band progression.


PS3: Energy

PS3.C: Relationship Between Energy and Forces

Primary School (K-2)

A bigger push or pull makes things speed up or slow down more quickly.

Elementary School (3-5)

When objects collide, the contact forces transfer energy so as to change the objects’ motions.

Middle School (6-8)

When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object.

High School (9-12)

When two objects interacting through a field change relative position, the energy stored in the field is changed.
