About this worksheet

Light and sound are different forms of energy that children can investigate with simple observations. Sound is made when matter vibrates, and changing a vibration can change what we hear. We see an object when light reaches it and then reaches our eyes. Materials may let most light through, some light through, or almost none through. This worksheet rotates among vibration evidence, light-source reasoning, material tests, and communication uses so it does not collapse two broad ideas into one repeated question. Support items use bells, drums, lamps, and clear or opaque materials. Challenge items ask students to choose a fair test or infer what changed from evidence. No decorative sound-wave or lamp picture is used because the current visual contract has no exact renderer for those investigations. Encourage your child to say what was observed before explaining it: the ruler moved back and forth, and a sound was heard.

What your child will learn

  • Connect sound with vibration
  • Explain why light is needed for sight
  • Compare how materials transmit light
  • Choose evidence from a fair light or sound test

Worked example

A plucked rubber band moves back and forth and makes a sound. The visible motion is evidence that vibration and sound occurred together.

Common mistake

Saying eyes send light outward, rather than recognizing that light must reach an object and then the eyes.

Helpful hint

Look for a vibration in sound tests and a light path in seeing tests.
