[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.
[4.ESS.3.1] -
Obtain information to describe that energy and fuels humans use are derived from natural resources and that some energy and fuel sources are renewable and some are not. Clarification Statements: Examples of renewable energy resources could include wind energy, water behind dams, tides, and sunlight. Non-renewable energy resources are fossil fuels and nuclear materials.
[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.3.4] -
Apply scientific principles of energy and motion to test and refine a device that converts kinetic energy to electrical energy or uses stored energy to cause motion or produce light or sound.* Clarification Statement: Sources of stored energy can include water in a bucket or a weight suspended at a height, and a battery.
