Have a container, and a measuring jug. Investigation: Have a container, and a measuring jug. Estimate the capacity of the container in • millilitres, and/or • litres and millilitres, and/or • half or quarters of a litre. Measure the capacity of the container using the scale on a measuring jug. Record the container’s capacity as the volume of water it can hold when filled to capacity in Reflection: How can we measure volume and capacity in litres and millilitres, millilitres, and halves and quarters of litres? Problem Solving Annie filled a container with water to half a litre. How many millilitres of water does Annie have? Problem Solving Annie filled a measuring jug with water to 1 litre. How many millilitres of water does Annie have? Measurement and Geometry 45

Record the volume of water. Investigation: Select an object with curved surfaces that will sink and a measuring device with a scale in millilitres. Pour a volume of water into the measuring device, for example, 500 millilitres or 1 2 litre. Record the volume of water. Estimate the volume of water the object will displace. Submerge the object in the water in the measuring device to measure the volume of water it displaces. Record the volume of water the object displaced as the volume of the object. Reflection: How can we measure the volume of objects using displacement? 350 mL Problem Solving This picture shows the water level in a measuring container before an object was submerged. This picture shows the water level in a measurement container after an object was submerged. What is the volume of the object? 700 mL Measurement and Geometry 45

Have 2 or more containers, and a measuring jug. Investigation: Have 2 or more containers, and a measuring jug. Measure the capacities of the containers using the scale on a measuring jug. Record each container’s capacity as the volume of water it can hold when filled to capacity in • millilitres, and/or • litres and millilitres, and/or • half or quarters of a litre. Place the containers in order of capacity. Reflection: How can we measure, compare and order volume and capacity in litres and millilitres, millilitres, and halves and quarters of litres?

Reflection: Can different containers have the same capacity? Investigation: Sit with a friend. Each of you have a different margarine, cream or ice cream container labelled with the same volume, for example, Each of you use a measuring jug to measure the capacity of your container by filling each container to capacity with water and measuring the volume of water. Label each container's capacity in litres and millilitres and/or in millilitres and/or in halves or quarters of a litre. Do both containers have the same capacity? Each of you record both containers and their capacities. Reflection: Can different containers have the same capacity? 500mL 500mL Measurement and Geometry 45

Reflection: Can different containers have the same capacity? Investigation: Select 2 containers – one short and wide, one tall and narrow, for example, a 1L drink bottle and a 1L ice cream container. Measure the containers’ capacities. Reflection: Can different containers have the same capacity? Measurement and Geometry 45

Measure the capacities of 2 containers. Investigation: Measure the capacities of 2 containers. Record each container's capacity as the volume of water it can hold when filled to capacity in litres and millilitres and/or in millilitres and/or in halves or quarters of a litre. Find a container with a capacity between the two containers. Record the new container’s capacity as the volume of water it can hold when filled to capacity in litres and millilitres and/or in millilitres and/or in halves or quarters of a litre. Reflection: How can we measure, compare and order volume and capacity in litres and millilitres, millilitres, and halves and quarters of litres? Measurement and Geometry 45

Investigation: Select an object with curved surfaces that will sink and a measuring device with a scale in millilitres. Pour a volume of water into the measuring device, for example, 500 millilitres or 1 2 litre. Estimate the volume of water the object will displace. Submerge the object in the water in the measuring device to check. Repeat with a different volume of water in the measuring device, for example, 900 millilitres. Record and compare the volume of water displaced each time. Did the volume of water displaced change? Did the volume of the object change? Reflection: How can we measure the volume of objects using displacement? Measurement and Geometry 45

Investigation: Select an object with curved surfaces that will sink and 2 measuring containers – one shorter and wider, and one taller and thinner, for example, Pour the same volume of water into each measuring container, for example, 500 millilitres or 1 2 litre. Submerge the object in the water in measuring container 1 and record the volume of water displaced / the volume of the object. Submerge the object in the water in measuring container 2 and record the volume of water displaced / the volume of the object.
