OUTCOME
A student:
MAe-12MG: describes and compares the masses of objects using everyday language
TEACHING POINT | As the terms ‘weigh’ and ‘weight’ are common in everyday usage, they can be accepted in student language should they arise. Weight is a force that changes with gravity, while mass remains constant. |
| Hefting’ is testing the weight of an object by lifting and balancing it. Where possible, students can compare the weights of two objects by using their bodies to balance each object, eg holding one object in each hand. |
| LANGUAGE | Students should be able to communicate using the following language: mass, matter, heavy, heavier, heaviest, light, lighter, lightest, about the same as, hard to push, hard to pull. |
EXPECTATIONS OF ATTAINMENT
Use direct and indirect comparisons to decide which is heavier, and explain their reasoning using everyday language (ACMMG006) | identify the attribute of ‘mass’ as the amount of matter in an object |
| use everyday language to describe objects in terms of their mass, eg heavy, light, hard to push, hard to pull | |
| use comparative language to describe mass, eg heavier, lighter, heaviest, lightest | |
| compare and describe two masses, such as by pushing or pulling | |
| compare two masses directly by hefting, eg ‘This toy feels heavier than that one’ | |
| record comparisons of mass informally using drawings, numerals and words |
