Activity: to identify different instruments for measuring [lo 2.3]

It is very important to be able to measure accurately. Long ago, people determined their mass with the help of stones. A stone of a particular mass was taken as the standard unit. If a person's mass was equal to eight such stones, for instance, the mass was given as eight stone. Since that time, technology has advanced and extremely accurate instruments have been developed for measuring.

The following is a list of some instruments that are very useful:

burette; gas sprayer, measuring cylinder, balance; callipers, measuring rod, digital mass meter, pipette, ruler, tape measure

ASSIGNMENT 5

Try to provide the correct names for the measuring instruments in the following illustrations:

Assessment

Learning Outcome 2: The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard 2.3: We know this when the learner interprets information by identifying key ideas in text, finding patterns in recorded data, and making inferences from information in various forms (e.g. pictures, diagrams, text).
