A source of light makes light. The Sun and other stars, fires, torches, and lamps all make their own light and so are examples of sources of light.
Some animals, such as fireflies and glowworms, are light sources. They make their own light to attract mates.
When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it.
Smooth, shiny surfaces such as mirrors and polished metals reflect light well. Dull and dark surfaces such as dark fabrics do not reflect light well.
Light travels in straight lines. When light hits an object, it is reflected (bounces off) and enters our eyes. This is how we see the object.
