Key Info
  • Sun and shadows
  • Duration: 01:05
  • How you can tell the time of day from shadows cast by the sun. The sun is our main source of light. Nuclear reactions at the core of the sun create energy in the form of heat and light. The light reaches us in just eight minutes and the earth depends upon it to grow and survive. The earth moves around the sun and, depending on the time of day, shadows formed by its light will be longer or shorter.

Ideas for use in class
