Transcript of Measure Volum Emy
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
• Capacity– Full and empty.
• Volume– Big, little, large, small, and tiny.
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.
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 volumeuntil 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

Volume – Measuring in Litres
The litre (l, l, L) is the standard unit of volume.

Activity 1- Measuring in litresMaterials :
some jars, large bottles, food cans, jugs, teapots and other containers.
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.
Results….
• Check whether you were right by pouring water from a 1-litre measuring jar into each container.
• Worksheet
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.
Continue….
• Try another container and estimate the volume of each container.
• Check for the actual capacity.• Worksheet 1
• Worksheet 2
Capacity - Comparison
• One to one comparison
• Many to one comparison
• Interactive activity
Capacity - Conversion
• 1 l (litre) = 1000 ml (millilitres)
l i t r e s ( l ) m i l l i l i t r e s (m l )
÷ 1000
x 1000
Teaching & Learning Activities
(a) Change litres to millilitres
1 l (litre) = 1000 ml (millilitres)
= 1000 ml1 litres
Addition Method
• Example :
2 litres = ? Millilitres
2 litres = 1 litre + 1 litre
= 1000 millilitres + 1000 millilitres
= 2000 millilitres
Multiplication Method
1 litre = 1000 millilitres
2 litres = ? Millilitres
2 litres = 2 x 1 litre
= 2 x 1000 millilitres
= 2000 millilitres
(b) Change Millilitres to Litres
(i) Addition method
Example :
2000 Millilitres = ? Litres
2000 millilitres = 1000 litres + 1000 litres
= 1 litre + 1 litre
= 2 litres
(ii) Division Method
Example :
1000 millilitres = 1 litre
2000 millilitres = ? litres
2000 millilitres = 2000 litres
1000
= 2 litres
