Measure Volum EmyPresentation Transcript

•
• 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.
• VOLUME
• 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
• Length Weight Volume Area Capacity Volume Descriptive language Big, little, large, small, and tiny Describe size of containers Sort out tiny buttons to fit in an egg cup Put the large pebbles into a pile in the garden
• Volume Size, fit, too big, too small, same, more, different Comparing two models to see which one is larger or smaller Length Weight Capacity Area Volume Comparative language
• 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.
• 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.
• Measuring scale
• Reading scale
• 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)
• litres (l) millilitres (ml)
÷ 1000 x 1000
• Teaching & Learning Activities
• Change litres to millilitres
• 1 l (litre) = 1000 ml (millilitres)
= 1000 ml 1 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
• Addition method
• Example :
• 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
