The Sky
    • Have you ever looked
      up at the sky and
      wondered what’s up
      there?
    • This presentation
      will tell you what’s up
      there and how to
      spot it.
             First Step
• You need to work out which way North
  is.
• Easy, use a compass, or if you stand
  facing the direction of Cheltenham from
  Gloucester, you will be facing East.
• Use your map skills to find North.
        What can you see?
• You can see stars, the moon and some of
  the planets.
• The planets you can see are Venus,
  Mars, Jupiter and Saturn.
• You can also see groups of stars, which
  are called Constellations.
             Stars & Planets
• At first glance, they all look the same, bright
  white dots.
• Stars twinkle and planets don’t.
• WHAT???
• If you look at a star it will blink at you, like a
  light being turned on and off very quickly.
• A planet won’t blink.
• Planets often appear earlier than stars and
  are lower in the sky.
• They are also often brighter.
How to know what to look for?
• The best way is to use a star chart.
