IV.1.m.6


LSD Units
 
5d

Investigate electrical devices and explain how they work, using instructions and appropriate safety precautions.
Key concepts: Flow of electricity for energy or information transfer. Safety precautions for using electrical appliances; grounding. Documentation for toys and appliances - wiring diagrams, written instructions. (See PCM-IV.2 m.3, transformations of energy.)
Real-world contexts: Situations requiring assembly, use, or repair of electrical toys, radios, or simple appliances, such as replacing batteries and bulbs; connecting electrical appliances, such as stereo systems, TV's and videocassette recorders, computers and computer components.

IV.2.m.4


LSD Units
 
5d

Describe common energy transformations in everyday situations.
Key concepts: Forms of energy, including mechanical, heat, sound, light, electrical, magnetic, chemical, food energy. See PME-IV.1 m.5 (electricity in circuits), PCM-IV.2 m.1 (energy in changes of state). Total amount of energy remains constant in all transformations.
Real-world contexts: Motors, generators, power plants, light bulbs, appliances, cars, radios, TV's, walking, playing a musical instrument, cooking food, batteries, body heat, photosynthesis (see LO-III.2 m.3, LEC-III.5 m.2).
