Seasons
  Lab
Seasons are caused by a
 combination of 3 things
  Is this how the Earth is
oriented in reference to the
            sun?
The Earth’s Northern axis
is always tilted toward the
        North Star
Direct sunlight transforms into
 more heat than indirect light
The Earth revolves
 around the sun
               Rotation
• Spin on axis
• Determines length of day


              Revolution
• orbit around
• Determines length of year
               How the Earth moves                      North Star
                 around the Sun
To determine seasons draw the equator at a right angle to the tilt
Then analyze which hemisphere receives more sunlight.
               Identify the Seasons
              Explain the Seasons                           North Star

                    Spring Between winter and summer

                                     Going from Summer to Winter


              Find Summer and winter first
In summary…
   Beginning Days of the Season
• Equinox
  – Daylight equals night time.
  – Sun is over equator
• Summer Solstice
  – Longest day of the year
  – Sun over North pole for northern summer
• Winter Solstice
  – Shortest day of the year
  – Sun over South pole for northern winter

                     Look closely at where the Sun is
                  hitting the Earth during each season:
