These quizzes practise concepts within this topic. Multiple-choice answers alone do not demonstrate drawing, conducting an investigation or using a digital tool.
Activities to practise beyond the quiz
- Supported by the guided activity; selecting an MCQ does not demonstrate this action.
- VC2M5ST02-C01Read a quantity at a stated time and distinguish a later increase from the size of a decrease.
- VC2M5ST02-C02Find the net change over several time intervals and compare the sizes of increases using the recorded readings.
- VC2M5ST02-C03A plotted line connects readings. A conclusion about unrecorded times requires an assumption about what happened between measurements.
- VC2M5ST02-C04Creating and communicating an interpretation of a real time-based relationship.
