Reading Scales with missing numbers
E.g. Find how big each small division is on this beaker
500
400
1) Count number of jumps =
4
2) Find value between the two numbers =
300
200
400 - 300 = 100
3) Divide value by number of jumps =
100 ÷ 4 = 25
100
Therefore each little division is 25ml.
What is the value of each little jump?

Meniscus
The meniscus is the
curved surface of liquid in
a cylindrical container.
Read from the BOTTOM of
the meniscus.
Important Point
• Read a scale at eye level
• Not from an angle
