How we explain it

Children can open this short lesson before they practice.

  1. The sun, a flashlight and a candle make their own light.
  2. We need light to see colors.
  3. Light passes through clear glass but not through a wall.

Example: Does a spoon make its own light? A spoon can shine, but only when light hits it. It does not make light. Answer: no
