Review the names and functions of the flower parts. Using the pollination diagram on the

overhead, demonstrate how pollen is transferred from one flower to the next.

For pollination demonstration using the overhead, you can stick a bee cutout on the eraser

end of a pencil and let it fly from anther to pistil.

Have real flowers available for students to examine closely with a magnifying glass or handlens. We recommend Easter Lilies, Day Lilies, Asian Lilies, or Tulips. (Caution, lily pollen

can stain clothes.)
