The Sun

Poster Activity

gravity and the sun
Gravity and the Sun
  • Gravity powers the Sun
  • Mass and gravity create extreme pressure and temperature at the core. (millions of degrees)
  • Conditions at the core cause hydrogen to be converted to helium
  • Nuclear fusion creates tremendous amounts of energy (millions of H-bombs)
  • Interesting Facts
    • The Sun is made of mostly Hydrogen and Helium
    • The Sun loses 4 billion Kg of mass per second (converted to energy)
    • Energy created at the core can take years to reach the surface
    • The surface of the Sun glows at a temperature of 5700 degrees
create a small poster of the sun
Create a Small Poster of the Sun
  • Use pages 335 to 340 of the textbook as a reference.
  • Your poster must show the following information:
    • The fuel and energy creation process at the core
    • The range of temperatures found on and within the Sun
    • The types of radiation given off by the Sun
    • Sunspots and how they help us determine the Sun’s rotation period of 27 days
    • The particles from the sun that are responsible for auroras on Earth
    • How communication satellites are affected by activity at the surface of the Sun.
