Physical Science
During this week-long institute, we discussed mechanical and chemical energy as it pertains to the 4th grade NGSS: PS3.
4th Grade Energy Performance Expectations
4th Grade Energy Performance Expectations
4-PS3-1 Use evidence to construct an explanation relating the speed of an object to the energy of that object.Clarification Statement: noneAssessment Boundary: Assessment does not include quantitative measures of changes in the speed of an object or on any precise or quantitative definition of energy.
4-PS3-2: Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.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: 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-PS3-4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.Clarification Statement: Examples of devices could include electric circuits that convert electrical energy into motion energy of a vehicle, light, or sound; and, a passive solar heater that converts light into heat. Examples of constraints could include the materials, cost, or time to design the device.Assessment Boundary: Devices should be limited to those that convert motion energy to electric energy or use stored energy to cause motion or produce light or sound.
