Light Around Us
Light helps us see. A source of light is anything that produces light.
- Natural light: the sun, stars, lightning, fireflies.
- Man-made light: lamps, torches, candles, phone screens.
Sound Around Us
Sound is made when something vibrates. Sources of sound include drums, bells, birds, cars and people talking.
Interesting fact: The sun is a natural source of both light and heat. We must never stare directly at it!
