Lesson Plan: Fertilization Science • Second Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the structure of sperm and that of egg cells (ova) in humans and explain how fertilization occurs.
Objectives
Students will be able to
- describe the basic structure of an egg cell (ovum) as a relatively large spherical cell with a nucleus, surrounded by a jelly coat,
- describe the basic structure of a sperm cell as a cell adapted for movement with a long tail, a midpiece, and a head containing the nucleus,
- outline how the structures of sperm and egg cells make them well adapted for their functions in fertilization,
- outline the basic events that occur during fertilization when a sperm and an egg cell fuse to form a zygote,
- describe the movement of the sperm and the egg cell prior to fertilization and implantation, including the movement of cilia in the oviducts,
- recall that a zygote will develop into an embryo, a fetus, and then a baby.
Prerequisites
Students should already be familiar with
- the fact that males and females have different reproductive systems,
- the fact that males and females can mate to produce offspring,
- the fact that ovulation occurs during the menstrual cycle.
Exclusions
Students will not cover
- the details of the acrosome or the zona pellucida,
