Entry 18: Reflective Time for Science (Light Energy)

My parents on the light when they watch the television,the basement of our condominium lights up when nighttime falls,the street lamps lining the street also light up at night,the lights at the bus stop illuminate it and while walking back home at night , we use it to find our way home.Light helps me do my homework at night and practically helps our whole family do lots of stuff.I think a world without light is as good as a world without sight,we need light to do almost everything and without it the world will be covered in darkness.
