Sources of light
Sources of light are things that give off light. Examples of sources of light are lamps, torches, candles, fire and the sun.
Sources of light game - Try getting various objects and see if they give off light in a dark room. Notice how shiny objects such as a mirror or a shiny spoon do not give off light which means that you won't be able to see in the dark with those objects. These objects are reflective and they simply reflect the light.
Sounds
We can hear sounds through our ears. The sound travels in invisible sound waves from the object to our ears. The further away the object is the quieter the sound is. If the object is near the object is louder.
