(4.6) Force, Motion and Energy
By fourth grade, students are ready to learn that energy exists in many forms, including mechanical, sound, electrical, light, and heat/thermal. They begin in-depth explorations of electricity, such as building electrical circuits, and they learn about conductors and insulators. Students also design an experiment to test the effect of a force on an object.
(4.6A) Forms of Energy
The student is expected to differentiate among forms of energy, including mechanical, sound, electrical, light, and heat/thermal.
(4.6B) Conductors and Insulators
The student is expected to differentiate between conductors and insulators.
(4.6C) Flow of Electricity in Circuits
The student is expected to demonstrate that electricity travels in a closed path, creating an electrical circuit, and explore an electromagnetic field.
(4.6D) Effects of Forces on an Object
The student is expected to design an experiment to test the effect of force on an object such as a push or a pull, gravity, friction, or magnetism.
