Light

Today I learned about light.  Light from the sun makes life on earth possible.  Without the sun, there would be no plants and without plants, there would be no air.  Without both plants and animals there would be no food.  Everything on earth would die and life wouldn't be possible.  Without the sun, evaporation wouldn't be possible, weather wouldn't be possible and neither would we!
We did an experiment where we could see light rays.  It was really cool.
