[4.PS.3.3] - 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. State Assessment Boundary: Analysis of forces or quantitative measurements of energy are not expected in state assessment.
[4.PS.3.1] -
Use evidence to construct an explanation relating the speed of an object to the energy of that object. State Assessment Boundaries: State assessment will be limited to analysis of kinetic energy. Accounting for mass, quantitative measures of changes in the speed of an object, or any precise or quantitative definition of energy is not expected in state assessment.
[4.PS.3.2] -
Make observations to show that energy can be transferred from place to place by sound, light, heat, and electric currents.
Clarification Statement: Evidence of energy being transferred can include vibrations felt a small distance from a source, a solar-powered toy that moves when placed in direct light, warming a metal object on one end and observing the other end getting warm, and a wire carrying electric energy from a battery to light a bulb. State Assessment Boundary: Quantitative measurements of energy are not expected in state assessment.
