Science Differentiation in action
How can we measure length?
• Ruler or metre stick
• Opisometer
• Trundle wheel
• Callipers
• Vernier callipers
metres (m).
Length is measured in __________
Science Differentiation in action
How can we measure area?
Regular shape
Use a ruler to measure the length
of each side. Multiply one side by
the other to find the area.
l
b
Irregular shape
Use graph paper. Draw around
the object and then count the
squares inside the lines.
metres squared (m2).
Area is measured in__________________
Area = l x b
You must know
the area of each
square on the
graph paper.

How can we measure volume?
Regular object
Use a ruler to measure length,
breath and height.
l
b
h
Multiply length by breath by
height.
Irregular object or liquid
Use a measuring cylinder.
How?
metres cubed (m3).
Volume is measured in ________________
(v = l x b x h)
Science Differentiation in action
How can we measure mass?
Place the object on an
electronic balance.
Mass is measured in ____________
Kilograms (kg).
