VOLUME & CAPACITY
OUTCOME
A student:
MA2-11MG: measures, records, compares and estimates volumes and capacities using litres, millilitres and cubic centimetres
| TEACHING POINTS | The displacement strategy for finding the volume of an object relies on the fact that an object displaces its own volume when it is totally submerged in a liquid. The strategy may be applied in two ways: using a partially filled, calibrated, clear container and noting the change in the level of the liquid when an object is submerged; or submerging an object in a container filled to the brim with liquid and measuring the overflow. See Y3 as well |
LANGUAGE | Students should be able to communicate using the following language: capacity, container, litre, millilitre, volume, measure, estimate. |
| Capacity refers to the amount a container can hold, whereas volume refers to the amount of space an object or substance (including liquids) occupies. |
EXPECTATIONS OF ATTAINMENT
Use scaled instruments to measure and compare capacities (ACMMG084) | recognise the need for a formal unit smaller than the litre to measure volume and capacity |
| recognise that there are 1000 millilitres in one litre, i.e. 1000 millilitres = 1 litre | |
| – relate the millilitre to familiar everyday containers and familiar informal units, eg 250 mL fruit juice containers, 1 teaspoon is approximately 5 mL (Reasoning) | |
| make a measuring device calibrated in multiples of 100 mL to measure volume and capacity to the nearest 100 mL | |
| use the millilitre as a unit to measure volume and capacity, using a device calibrated in millilitres, eg place a measuring cylinder under a dripping tap to measure the volume of water lost over a particular period of time (Sustainability) | |
| record volumes and capacities using the abbreviation for millilitres (mL) {Literacy} | |
| convert between millilitres and litres, e.g. 1250 mL = 1 litre 250 millilitres | |
| compare and order the capacities of two or more containers measured in millilitres | |
| – interpret information about volume and capacity on commercial packaging {Communicating, Literacy} | |
| estimate the capacity of a container in millilitres and check by measuring | |
| compare the volumes of two or more objects by marking the change in water level when each is submerged in a container | |
| – estimate the change in water level when an object is submerged {Reasoning, Critical and creative thinking} | |
| measure the overflow in millilitres when different objects are submerged in a container filled to the brim with water | |
| estimate the volume of a substance in a partially filled container from the information on the label detailing the contents of the container |
