ADAPTATIONS BY ANIMALS
As we mentioned earlier, plants and animals differ from each other in one aspect in particular. Animals move, while plants are anchored. Animals are dependent on other animals for their food, or they live from plants. Some animals live on dry land, while others live in water. Some animals have only two legs, others have four or even more legs. Some even have none at all!
Animals are divided into groups on the basis of the characteristics. Lets us take a closer look:
MAMMALS
Mammals feed their young with milk that is produced in the body of the female.
The young are born alive.
Mammals are the only animals with hair or fur (except for the dolphin and the whale).

Some people say that elephants have very large ears so that they can hear well. Other people say the large ears play an important role in cooling down their bodies.
What do you think?

Is the elephant a herbivore, a carnivore or an omnivore?

LEARNING OUTCOME 2:CONSTRUCTING SCIENCE KNOWLEDGEThe learner will know and be able to interpret and apply scientific, technological and environmental knowledge.
We know this when the learner:
2.1 recalls meaningful information: the minimum requirement is to describe the properties and characteristics of objects, substances and organisms in simple terms;
2.2 categorises information: creates own category of objects and organisms and explains own rule for categorisation;
2.3 interprets information.
Task:
Some say the large ears serve to cool the animals. There are small veins just under the skin on the surface of the ear. Heat is lost through these veins and this prevents overheating.
The elephant is a herbivore.
