Worksheet Overview

QUESTION 1 of 10

Babies grow and at around 12 months they become toddlers. Toddlers become children at about 3 years. Children between the ages of 10 to 15 experience massive changes in their bodies. Fast growth takes place during this period. This period is called puberty and finishes by the age of 18. Usually girls go into puberty before boys.

 

Spots or acne

 

Sex hormones released by the ovaries and testes start off puberty. Sex hormones can cause acne (spots) and emotional changes, too. This includes boys and girls becoming more interested in each other. The period during which all the physical and emotional changes take place is called adolescence.

 

The changes that take place during adolescence in boys and girls are summarised in the table below:

 

Development of male characteristics Development of female characteristics
stronger body smell stronger body smell
voice deepens 'breaks'  
testes and penis get bigger menstruation
testes start making sperm ovaries start releasing eggs

  • Question 1

What age marks babies becoming toddlers?

CORRECT ANSWER
12 months
EDDIE SAYS
Obviously, because everyone's different, growth changes happen at different times for different people, but babies start to toddle around relatively unaided from about a year old.
  • Question 2

At what age do toddlers become children?

CORRECT ANSWER
3 years
EDDIE SAYS
Toddlers gradually morph into children as they become a little more independent, walking and running with only occasional mishaps, chattering away and learning social skills and these changes mean that by the time they're about 3, we refer to these little ones as 'children' rather than 'toddlers'. School beckons!
  • Question 3

What is the name of the period during which fast growth takes place in children?

CORRECT ANSWER
puberty
Puberty
EDDIE SAYS
This growth spurt is really quite marked and many young people find this a trying time ("growing pains"), let alone all the changes that their bodies start going through. Puberty is the name given to this time of massive bodily growth and change.
  • Question 4

Is this statement true or false?

 

Girls usually go into puberty before boys.

CORRECT ANSWER
true
EDDIE SAYS
Obviously, everyone's different, but as a trend girls tend to start puberty at a slightly earlier age than boys do.
  • Question 5

Complete this sentence:

CORRECT ANSWER
EDDIE SAYS
Sex hormones are released by the testes and ovaries and are responsible for starting off puberty. Throughout the years over which the bodily and emotional changes take place, these sex hormones have an important role to play in directing those changes and the development of the adult body.
  • Question 6

What is the name of the spots that are seen on the face of some teenagers?

CORRECT ANSWER
acne
Acne
EDDIE SAYS
Acne has so many names: spots, zits, blackheads and so on and people are affected by acne to differing extents. Because they are caused by these hormonal changes, which result in substances being released from skin pores, simply washing our faces with soap and water can make a real difference. There are lots of facial products out there too and, for some unlucky folks, the acne is so bad that they have to seek medical treatment to clear it up.
  • Question 7

What is the name of the period in life where physical and emotional changes take place in teenagers?

CORRECT ANSWER
adolescence
Adolescence
EDDIE SAYS
So, adolescence is a period of life when teenagers go through all these physical and emotional changes - it's a bit like a caterpillar turning into a butterfly: you have to go through this rather difficult stage to emerge as a beautiful butterfly, ready to spread your wings and explore the world!
  • Question 8

What is a common physical change that both boys and girls experience?

 

Two answers apply.

CORRECT ANSWER
underarm and pubic hair grows
stronger body smell
EDDIE SAYS
Testes is clearly a boy thing and girl's hips widen during adolescence. However, in both boys and girls underarm and pubic hair grows and body smell becomes stronger.
  • Question 9

Tick two changes that take place in girls during puberty.

CORRECT ANSWER
breasts develop
hips get wider
EDDIE SAYS
During puberty, girls' breasts develop and their hips get wider, both of which are changes to prepare the young woman's body for bearing children: wider hips to allow the baby to be born and breasts to provide milk for the baby.
  • Question 10

Tick two changes that take place only in boys during puberty.

CORRECT ANSWER
chest hair develops
testes and penis get bigger
EDDIE SAYS
For adolscent boys, their testes and penis grow, ready for having sex, and hair often develops on young men's chests, as well as on their faces. Both girls and boys develop hair under their arms as they mature.
