Group of Animals...

Does this fish has SCALES..or NOT 

Hi everybody..


As i teaching year 3 Science Students last week, i remember that animals can be categorized to many groups.
Animals can be group by looking at their EXTERNAL FEATURES...
For examples, fish has their own fin, scales and tail...
Cat also has tail, no scales but it has furs, whiskers, claws and legs...
Snake also has scales as the fish, and the tail also
So, i can group all of these 3 animals in one group.....the group of animals with TAILS...hehe..


But when we study the animals thru real SCIENCES, they are not in the same group....
So now...just for fun... i wanna group the animals in ZOO NEGARA MALAYSIA into 3 GROUPS :


1.  ANIMAL WITH LEGS
Tigers, Lions, Birds, Elephants, 
Giraffe, Zebra, Goats, Deer, 
Monkeys, etc...
...too many of themm..


2.  ANIMALS WITH HAIR
Elephants, Goats, Tigers, Deers, 
Mousedeers, Giraffe, 
Monkeys, Zebras, ets...


3.  ANIMALS WITH SCALES
Fishes, Snakes, 
What else do you think ?...
try to figure it out....hehehe
...ask your children......
