LESSON CONTENT

MEASURING LIQUIDS

Liquid is measured using standard measuring instrument like measuring cylinder and beaker to get it quantity and amount of volume.

MEASURING THE VOLUME OF LIQUIDS IN MM3 AND CM3

Liquids like water, kerosene, petrol, oil can be measured. Graduated jars, measuring cylinder, pipette can be used to measure the volume of liquids.

Units of Measurement of Liquids:

1000 CUBIC millimetres (MM3) = 1 cubic centimeter (cm3)

1000 cubic centi metres (cm3) = 1 cubic decimeter (dm3)

1000 cubic decimeter (dm3) = 1 cubic metre (m3).

1 cubic metres = 1000 litres.

IMPROVISING A MEASURING CYLINDER

Measuring cylinder can be gotten by making use of the following materials: paper, cardboard, empty jar, ruler and pen.

INSTRUCTIONAL PROCEDURE

• The Teacher revises the previous lesson (Measurement).
• The Teacher introduces the lesson through question and answer (MEASURING LIQUIDS).
• The Teacher explains the lessons.
• The Teacher write the note on the board.

LEARNERS ACTIVITIES

Learners participate in the class discussion

LESSON EVALUATION

1. State three ways by which Liquids can be measured.
2. The unit of volume is __________________
3. Mention three local materials that you can used to make a cylinder.

CONCLUSION: the teacher summarize the lesson.
