5.)Give students a copy of the Life Cycle of Gymnosperms, (this should be with your resource material, or get a copy from (thinkfinity.org).
6.)The teacher will use a transparency on an overhead projector or SMART board to go over and explain the Life Cycle of the Gymnosperm.
7.)Be sure to review meiosis (cell division of the sex cells)as you go over the lesson. Meiosis should have been covered earlier.
