Light & Sound

Bright, dark, loud and quiet

What your child practices

Sources of light and sound, loud and quiet, high and low sounds, shadows, and how light passes through glass but not walls.

Maine Learning Results learning standard: 1-PS4-1; 1-PS4-2; 1-PS4-3 · sound and vibration, seeing only with light, and how materials block or let through light

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
