instructions on how to

carry out the activity.• Teacher directs the

students to carry out the

activity.•Teacher and students

discuss the answer.

VARIATION AND FACTORS THAT CAUSE VARIATION


BY THE END OF THE LESSON :

A student is able to :

• State what variation is

• List variation in humans

• Identify factors that cause


THE MEANING OF VARIATION

The diffrences among individuals of the same

species.


The students are differ :

• Height• Weight• Hair type• Skin colour


There are 2 factors thatcaused variation.

• Genetic Factors

• Environmental Factors


GENETIC FACTORS

1. Genetic factors are inherited.

2. The examples of variations caused

by the genetic factors are :


Types of blood


Colour of eyes


Colour of hair


Types of ear lobes


Types of hair


Pattern of thumb print


Ability to roll the tongue


ENVIROMENTAL FACTORS

1. Environmental factors are

not inherited.

2. The examples of variations caused

by the environmental factors are :

Expose to excessive sunlight

Before joining After joining

The skin colour of the boy has changed. He is tanned.
