Can we observe an
                              eclipse of the Sun
                              with our naked eyes?
                                                       Oh, no you can’t! Looking directly at
                                                       the Sun or an eclipse of the Sun with
                                                       our naked eyes can damage them
                                                       permanently.



                       We should use suitable filters such as special glasses
                       when watching an eclipse of the Sun.



            What are other safe ways to observe an eclipse of the Sun?

             1.  Sketch and label the positions of the Sun, Earth,
               and the Moon correctly during an eclipse of
               the Moon and an eclipse of the Sun.                                             MOON
             2.  Colour your sketch.                                                   EARTH
