Reproduction for year 6

2. Unit 1 interaction-
Reproduction

3. Female reproductive system
Once a month a
women´s ovary will
release an egg.
This will normally
take place 14 days
after the start of
the period.
The egg goes through the fallopian tubes where the
egg slows down (every 28 days). This is where the
egg Will meet the sperm cell.(fertilisation)

4. Male reproductive system
What does each part do?
Testicle- Makes the
sperm (very important)
Scrotum- The skin that
holds the testicles. This
part protects the testicles.
Penis- Where the sperm
and urine travel
Prostate gland- This gland
produces some of the liquid
part of semen.
Seminal vesicles-Similarly,
this gland also produces some
of the liquid part of semen.
Vas deferens: Tubes which go from the
testes to the seminal vesicles, through
which the sperm travels.

5. Why do we need to reproduce?
What would happen if we did not?
Can you think of any examples of
animals did not reproduce enough?

6. Genes
Human beings pass on some
characteristics to their offspring
through genes.

7.  Your genes are part of what makes you the person you are. You are different
from everyone alive now and everyone who has ever lived.
 DNA
 But your genes also mean that you probably look a bit like other members of
your family. For example, have you been told that you have 'your mother's
eyes' or 'your grandmother's nose'?
Genes influence what we look like on the outside and how we work on the
inside. They contain the information our bodies need to make chemicals
called proteins. Proteins form the structure of our bodies, as well playing an
important role in the processes that keep us alive.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic
acid'. The DNA molecule is a double helix: that is, two long, thin strands
twisted around each other like a spiral staircase.

8.  Genes
 A gene is a length of DNA that codes for a specific protein.
So, for example, one gene will code for the protein
insulin, which is important role in helping your body to
control the amount of sugar in your blood.
Genes are the basic unit of genetics. Human beings have
20,000 to 25,000 genes. These genes account for only
about 3 per cent of our DNA. The function of the
remaining 97 per cent is still not clear, although scientists
think it may have something to do with controlling the
genes.

9. Humans have about 24000 genes.
Parents pass onto their children
characteristics such as eye and hair
colour.
Which part of the eye gives it its colour?

10. Analise and organise:
making your album
 Our lives have different stages which we pass through from birth to death.
 Each stage has its own characteristics and marks our passage through life.
Make your album analysing and organising your different stages. Ask and
interview your parents to get information, for example, When you were a
baby, did you grow by breast feeding or bottle feeding ? Weight? Height?
Were you active or quiet? When did you start talking? When did you start
walking?....
 Stage 1:baby, cannot walk or talk (0-12 months)
 Stage 2: toddler, starts walking and talking (1-3 years)
 Stage 3: child, fully mobile, learning to function in society
 Stage 4: adolescent, becoming independent
