                   Bees and honeycombs




Why does the bee choose a hexagon for the shape of its cell
               when it builds a honeycomb?

Which regular polygons will tessellate?

Find which of the following six polygons tessellate. Trace and
cut out from card a few of each polygon. Are they any other
regular polygons which you should try?




Can you explain why only shapes which tessellate would be
useful for building a honeycomb?

Materials you will need :
several sheets of card      a ruler    scissors    tracing paper

    Pupil Guidance :

  1. You will need at least 36 of each tessellating polygon.
     Cut them out of card to the sizes on the given sheet.

  2. Draw a square of side 30cm on a large sheet of paper to
     represent the space available for the honeycomb inside
     the hive. Choose one of the polygons and cover as much
     of this square as you can with a tessellation.
     Find the total length of the network of the sides of the
     pieces which you have used. This total length gives you a
     measure of the amount of wax which a bee would use to
     make this cross section.

  3. Repeat with each of the tessellating polygons. You should
     use the same number of pieces in each case. Find the
     total length of the network of sides for each attempt.

        Copy this table and enter your results.

Name of polygon         Number of           Total length of the
                       polygons used         network of sides.



  4. Which shape would use the most wax in a honeycomb?

    Which shape would use the least wax?

    Which shape do the bees actually use when they build
    honeycombs? Can you suggest a reason for their choice?
