HANDOUT: Story: The Very Important Journey
HANDOUT: Step by Step Conception “Y” Activity
ANSWER KEY: Step by Step Conception “Y” Activity
SLIDE: Fertilization
SLIDE: Implantation
SLIDE: Sperm Production
INTRODUCTION:
This lesson brings together the anatomy and physiology from previous lessons to
explain in detail the process of fertilization and conception.
APPROACHES/STRATEGIES:
A. GROUND RULES (5 min)
Ensure ground rules are established before beginning this lesson. For classes that
have already established ground rules, quickly reviewing them can promote a
successful lesson.
B. CONCEPTION/ FERTILIZATION STORY (15 min)
This story explains how sperm production, ovulation and conception are related. It
walks through the stages of fertilization and implantation, and provides a detailed
explanation of how each step fits into the process.

GRADE 5 ANATOMY & PHYSIOLOGY LESSON 6
1. Distribute the Very Important Journey handout to
students.
2. Have students follow along with their handouts
C. CLASS DISCUSSION
These questions allow students to review their
knowledge of the process of conception, fertilization and
implantation.
1. What is the process called when the ovum is
released from the ovary?
• This process is called ovulation, and it starts in
females during puberty.
You may want to
show or hand out the
diagrams of sperm
production,
implantation, and
fertilization as you
read the story to
illustrate where the
journey is taking
place.
2. What happens during the process called ejaculation?
• This is when sperm cells mixed with semen, are released out the end of
the penis.
• This can happen during sexual intercourse, masturbation, or sometimes
when a boy is sleeping which is called a wet dream.
3. When the sperm cells find the ovum in the fallopian tube all the cells try
to break through the outer layers of the ovum cell. What is it called when
one successfully breaks through and attaches to the ovum?
• This is called fertilization, one of the two processes before conception is
complete.
4. What is it called when the sperm and ovum cell which have joined
together, travel into the uterus and attach to the uterine lining?
• This is called implantation.
• This process completes the whole process of conception.
5. Who can you ask if you still have questions about sexuality?
• Parent
• Trusted Adult
• Teacher or Guidance counsellor
• Doctor or Nurse
D. STEP BY STEP CONCEPTION (15 min)
Students demonstrate knowledge of the components of
the human reproductive system and the process of
conception.
1. Using the Step by Step Conception handout and
cards cut out each individual step, and shuffle them.
2. Hand out steps and the “Y”. Have students place
each step in order along the “Y”
3. Use Answer Key to ensure all steps are in the
correct order.

If you would like to
do this activity as a
larger group, you can
make your own “Y” on
Newsprint, and
enlarge the cards.

GRADE 5 ANATOMY & PHYSIOLOGY LESSON 6 HANDOUT
A VERY IMPORTANT JOURNEY
Once upon a time there were two important cells. One cell was made and stored in a testicle, and it was called a sperm cell. The other was stored in
an ovary and was it was called an ovum. These two cells had a very important journey to make! For if they were to meet one another an awesome
event would happen. The sperm cell had the longer journey to make. The sperm cell needed to travel from the testicle through the vas deferens all
the way to the urethra and out of the end of the penis into the vagina, then through the cervix, through the uterus, and into the fallopian tube. There
it would meet the ovum.
As the sperm cell travelled through the vas deferens it mixed with other fluid and was now called semen. The process where semen leaves the
penis is called ejaculation. In order for the two to meet, the ovum would mature and leave the ovary. It would travel out of the ovary and into the
fallopian tube. The process where the ovum leaves the ovary is called ovulation. This full journey is able to happen through sexual intercourse, this
is when a man’s penis enters the women’s vagina, sperm cells in semen squirt (ejaculate) out of the end of the penis and inside the woman’s
vagina. Hundreds of millions of sperm cells ejaculate out of the penis, however only around 1,000 make it as far as the fallopian tubes. The Semen
containing sperm travel from the vagina, through the cervix into the uterus in search of the ovum.
Once the sperm found the ovum they started to try to break through the outer lining of the ovum. One sperm cell broke through the lining and
attached to the ovum. This breaking through and attaching process is called fertilization. Once one sperm cell enters the egg none of the other
sperm cells that made the epic journey can enter. The two cells now became one. This new cell began to divide into two identical cells, and those
two into four, and those four into eight and so on, until many cells formed a larger ball of cells. This new ball of cells continued to travel through the
fallopian tube into the uterus. Once this cell entered the uterus, it found a comfortable place to rest, and it attached itself to the wall of the uterus.
This is called implantation. Once implantation has happened, the process of conception is complete, and the ball of cells begins to grow into a baby.
The awesome event has happened, and a new journey has begun: the journey of the developing baby.
