Unit 2.2 Forms of Energy
Students in grade 4 investigate observable effects of light using a variety of light sources. Students predict, describe, and investigate how light rays are reflected, refracted, and absorbed. They also describeor show that heat can be produced in many ways. These concepts should be taught at the reinforcementlevel of instruction.
Fourth-grade students demonstrate an understanding that heat moves from warm objects to cold objects until both objects are the same temperature. Students draw, diagram, build, and explain a complete
electrical circuit, which should be taught at the reinforcement level to the drill-and-practice level of instruction. In addition, students use experimental data to classify a variety of materials as conductors or insulators.
