What will happen to Earth during an eclipse of the Moon?

                        The pictures below show the difference in the level of the sea tide at
                        a jetty during the crescent moon phase and an eclipse of the Moon.

             What can you predict from the level of sea tides during an eclipse of the Moon?







                                                  Pinhole Camera


            Make a pinhole camera using a pair of scissors, adhesive tape, pin, two pieces
            of white cardboard, and aluminium foil.
                                                                        Be careful when using
             Steps:                                                     scissors and pins.

               Make a square hole           Paste an aluminium            Make a few holes on
               in the centre of the         foil to cover the hole.       the aluminium foil. The
               cardboard.                                                 holes made are known
            4.                                                            as pinholes.



                                                                           An eclipse of the Sun
                                                                           can be viewed safely

              Allow the sunlight to pass
              through the pinholes until it forms
              a clear image on the surface of
              the other cardboard.                                                                   175
