      Over the thousands of years, sediments enters
      the mould to make a cast fossil.
      An animal dies. It gets covered with sediments
      which eventually become rock.
      An erosion and weathering take place,
      eventually the fossil becomes exposed.
      More layers of rock cover it. Only hard parts of
      the creature remain such as the bones and teeth.
      Changes in sea level take place over a
      long period.

6) True or false?

     An archaeologist studies fossils.

7) Soil is made      up      of a        mixture       of   things.     Name
      two of them.

                                                                                   and objects that do not reflect well.
1) Write true or false next to each statement.
                                                                                     Objects that reflect well             Objects that do not
    Light travels in zigwigzag lines.                                                                                          reflect well
    Light travels in zigwigzag lines.

    When light hits an object, it stops.

    We see when reflected light hits our eyes.

2) Draw lines to show                       how          light   reflects    off
       these two different surfaces.
                                                                                   4) Name three light sources.
                                                          A rough and
                                                         uneven surface.

                                                                                   5) Fill in the missing words in the passage below:

                                                                                      The                 control the amount of

6) Match the words to the correct definitions:                        8)  Say whether each statement is true or false.

                                                                       A shadow is caused when light
