TEACHING AIDS

2.1  USES of COMMERCIALLY-AVAILABLE PLASTIC-BASED BOTTLES AS
AIDS

Some of the suggested commercially available plastic based bottles are bottled fruit
juices or mineral water.
I would like to choose these materials as my teaching aids due to several reasons:
i) Plastic-based bottled juices or mineral water are easily available from a small
minimarket to large supermarket and even vendor machines.
ii) They are easily available at reasonably low price and thus making it affordable as a
classroom teaching aids without creating burdens for parents.
iii) They are available in various dimensions for a certain volume. For example, a bottle
of 500 mL for a particular brand may be sold with different dimensions from other
brands. This inadvertently enables the students to understand the concept of volume
measurement in different types of similar containers. 

v) They can be recycled which is in support of government policy and at the same time
create awareness among students in regards of recycling.
v) They can also be reused as mediums for craft arts teaching among students.

2.2  USES of KITCHEN UTILITIES AS AIDS

Some of the suggested kitchen utilities are drinking glasses and bowls. I would like to choose
these materials as my teaching aids due to several reasons:

i)    Drinking glasses or bowls is necessary in every kitchen utilities list thus there is no problem of availability. Besides, they are available in plastic or paper-made form that reduces the risk of harm due to the fragility of glasses or bowls made of glass or ceramics. 

ii)   It does not create burden to parents since it is already available in each houses.

iii)  They are available in various dimensions for a certain volume. For example, a glass of 250 mL may be available with different dimensions. This inadvertently enables the students to understand the concept of volume measurement in different types of similar containers. 

iv)  Students can easily associate with such aids since they are common use items in households.
