**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.
