3. Importance and organisation of science laboratory
The new approach to science education give prominence

activity oriented subject.Specially arranged place is needed in
higher classes for conducting the activities.A school laboratory
is essential to transact scince in the activity based method.
There are few things to be remembered while organising a
science laboratory.They are ;
4. Make a list to be taken care of when
equipping a science laboratory
Make a list of apparatus and chemicals
needed
It is good to have enough apparatus
proportionate to the number of students
Glass apparatus need to be kept safely in
separate almirahs
Arrange chemicals in their alphabetical
order
Bottles must be labelled clearly
After use apparatus must be cleaned and
kept back in their respective places
5. The walls of the laboratory can be decorated with
pictures of scientists and diagrams of apparatus
Useless substances,broken glass,chemicals,solid
waste etc:must be deposited in a separate basket
A basket full of water must be kept not only when
experiments are being done but always
6. ACCIDENTS AND FIRST AID
Accidents may happen in the laboratory.So it is necessary
to keep a first aid kit.Possible accidents and their
remedies in the laboratory
a. Wounds :- apply cotton dipped in tincture iodine
b. Burns from fire :- cover the portion with linen dipped in
vaseline
c. Burn from acids :- wash with plenty of water and then

7. A first aid kit must contain the following :
Rectified spirit,scissors,dressing gauze,linen,
Forceps,bandage,plucker,cotton,eye dropper,
Plaster,glycerin,tincture iodine,acetic acid 1% sodium
bicabonate,milk of magnesia,carbonate acid and vaseline
8. REGISTERS IN THE LABORATORY
1. Permanent Stock register :- which contains details
of articles which are not liable to be broken or
consumed
2. Breakable stock register :- it includes articles of
glassware,flask,test tube,beakers,watch
glass,funnel,burettes
3. Consumable stock register :-it includes chemicals
and other fluids liable to be consumed
4. Order register :-it includes the record of the order
sent for the purchase of new apparatus
5. Requirement register :-This includes items required
for this priority should be given to those of
