3.  Definition
 A model is a recognizable representation of a
real thing three dimensionally,that is height
width and depth is felt as reality
K.BASAVANTHAPPA

5.  solid models:it is the replica of an original
thing made with some suitable material like
clay plaster of parise wood,iron etc.
 Eg.globe,clay model

7.  Are the replicas of the original things to show
internal parts of a thing
 eg .cross sectional model of human body

9.  these models are either actual working things
or their miniature replicas

 eg.a motor,a generator

11.  sand models:made by using sand,clay,saw
dust,
 eg.tribal village ,forest area

13.  scale models: in order to form a correct idea
of an object scale models are used
 Eg:models of organs of human body

15.  Cardboard
 Plastic

16.  1.accuracy
 2.simplicity
 3.utility
 4.solidity
 5.ingenuity
 6.useful

17.  1.model heighten reality of things and make
learning direct and meaningful as they are three
dimensional
 2.models illustrates the application side of
certain principles and laws
 3.models simplifies the complex subjects
 4.models are lasting and helping as a teaching
aid
 5.still models are easy to make with discarded
materials
 6.reasonable size and easy to carry


28.  Mould can be made up of plastic material to
stimulate some life object
 Eg.body which shows evidence of trauma
infection ,disease,surgical intervention

 2.ideas can be easily moulded into shape
 3.easy to handle
 4.long lasting

31.  It is a three dimensional arrangement of
related objects models and cut outs to
illustrate a central theme or concept
 The objects are placed in a big box or show
case with a glass covering and background
printed with a a shade or a scene
