• Laboratories have now become indispensable in schools, factories and researchinstitutes to test, confirm, or demonstrate on a small scale, phenomena andprocesses which occur in nature or which may find application in industry or be ofimportance to science

• The equipment of a chemical laboratory varies according to the nature of the work,which is to be carried out It may be intended for the student to put to the test histheoretical knowledge/ school laboratory, for the technician/ technologist to verifyand check processes to be employed in the factory/ works laboratory or to help thescientist and research worker to discover or confirm scientific facts/ researchlaboratory

• Every chemical laboratory should be provided with running water, gas andelectricity The water supply is conducted from the mains by means of pipes, thepiping terminating in taps under, which there are sinks to take away waste waterand other non-objectionable liquids When one needs water one turns the tap onand stops it flowing by turning the tap off Similarly, a system of pipes is attached tothe gas main from where gas reaches the various kinds of burners They serve forproducing flames of different intensity, the Bunsen burner being the most commontype used

LESSON 4 – Text 1

“Voice” refers to the way the verb is used in the sentence Remember

that a sentence has to have a subject and a verb, and many verbs require direct objects Here’s an example of active voice:

subject verb direct object

Babe hit the baseball

doer action receives action

In passive voice, the subject of the sentence also receives the action.

The doer of the action is someone else Here’s an example of passive

voice:

subject verb

The baseball is hit by Babe

receives action action who did the action
