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
Using descriptive language
Full and empty.
Big, little, large, small, and tiny.
Volume and Capacity
This is the amount of space something takes up. There can be liquid volume or solid volume.
Only containers have capacity. The capacity of a container is the maximum volume of liquid it can hold.

3. Children don’t conserve volume
until they are much older
Using the same piece, make another model
5. Displacement activity:
What happened when an
object is dropped into it
Use language: same, more, different

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