2. Conservation (keabadian) is one of fundamental
idea in learning of volume.
If we rearrange a set of counters in different ways,
we do not alter the number of the counter.
Conservation of liquid
-If we empty the water from one container into
another differently shape container, the volume of
water is still remain.
Conservation in Capacity
4. Volume and Capacity
• Volume
This is the amount of space
something takes up. There can be
liquid volume or solid volume.
• Capacity
Only containers have capacity. The
capacity of a container is the
maximum volume of liquid it can
hold.
5. 1. Language development : size,
fit, too big, too small
2. Can be develop through
making comparisons
-Which one smaller or larger,
and begin to develop the
volume concept.
3. Children don’t conserve volume
until they are much older
4.Playdough
- Making models
- Using the same piece, make another model
5. Displacement activity:
- What happened when an
object is dropped into it
- Use language: same, more, different
7. Volume
Size, fit, too big, too small, same,
more, different
Comparing two models to see which
one is larger or smaller

8. Volume – Measuring in Litres
The litre (l, l, L) is the standard unit of
volume.
Measuring scale 1
Measuring scale 2
9. Activity 1- Measuring in litres
Materials :
some jars, large bottles, food cans,
jugs, teapots and other containers.
10. Sort them into 3 groups.
(a)Those that you think will hold about 1
litre of water.
(b) Those that you think will hold less
than 1 litre.
(c) Those that you think will hold more
than 1 litre.
11. Results….
• Check whether you were right by pouring
water from a 1-litre measuring jar into
each container.
• Worksheet
12. Measuring in millilitres
The millilitre (ml, mL) is the unit
commonly used in measuring the
volume of small containers.

Reading scale
13. Activity 2 – Measuring in Millilitres
• A medicine spoon holds 5 millilitres (ml).
Estimate first and then use a 5 ml spoon
to measure the volume.
14. Continue….
• Try another container and estimate
the volume of each container.
• Check for the actual capacity.
• Worksheet 1
• Worksheet 2
15. Capacity - Comparison
• One to one comparison
• Many to one comparison
• Interactive activity
16. Capacity - Conversion
• 1 l (litre) = 1000 ml (millilitres)
litres (l) millilitres (ml)
÷ 1000
x 1000
17. Teaching & Learning Activities
(a) Change litres to millilitres
1 l (litre) = 1000 ml (millilitres)
= 1000 ml1 litres
