  • Slide 2
  • In your notebook write the following: Three things you already know about the Sun Two things you find interesting about the Sun One question you still have about the Sun (C) Copyright 2014 - all rights reserved www.cpalms.org
  • Slide 3
  • The Sun is a star. It is a large ball of gas. The provides energy for us on earth. The Sun is a yellow star. It is a main sequence star. It is really hot. It produces energy through nuclear fusion Question- Why does it have temperatures? How is the Sun similar to Earth? (C) Copyright 2014 - all rights reserved www.cpalms.org

  • Radiation-energy transfer as particles or waves Hand wiggles like a snake or wave up and down Conduction- energy transfer by touching Clap hands together Convection- energy transfer by circulation or movement in a liquid or gas Hand moves in a circular path (C) Copyright 2014 - all rights reserved www.cpalms.org
