How energy travels around
CONCEPTUALObserve and provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents
Mastery Evidence
- Give at least one example of energy transfer by each: sound, light, heat, electric current
- Explain that energy moves from a source to a destination through these means
- Describe how electric currents transfer energy from a battery to a bulb through wires
Assessment Prompt
“Can [child] give examples of how energy moves around — like heat from a radiator warming a room, light from a lamp reaching your eyes, or electricity flowing through a wire?”
