it  completely  disappears  from the

          sky. The whole  process  is reversed

          until the full moon appears in about

          a month. The different shapes of the
          moon that we see are called the phases


          of the moon.

              Out     How many days does it take for a
                      new moon to become a full moon?                            Phases of the Moon
          Sun

          The sun is a star and the ultimate

          source  of  all  kinds of  energy we

          have on Earth. We can see the sun

          in the sky during the day. The sun is

          the nearest star to the Earth. As the
          sun is the closest star to the Earth,
                                                                               The Sun and the Earth
          it appears to be much bigger than the other stars.

          The sun is a huge ball of hot gases. It gives us heat and light. All the eight

          planets revolve around the sun in their fixed orbits. The sun’s gravitational

          force holds the Earth and the other planets in place.

          We get enough light from the sun to allow living things to grow.



           Think &    We  all  know that  the  Earth  rotates  around the  Sun, and  the  moon rotates
           Answer
                      around the Earth. What happens when the moon comes between the Earth
                      and the Sun?



          Stars

          Stars are the heavenly bodies that have light

          of their own. We see many stars at night. They
          are very big, but they look very small as they

          are very far away from us.
