AC9S3I03 • Year 3 Science
follow procedures to make and record observations, including making formal measurements using familiar scaled instruments and using digital tools as appropriate
Students learn to follow procedures to make and record observations, including making formal measurements using familiar scaled instruments and using digital tools as appropriate. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
Learning routine: Observe → Model → Investigate → Record → Explain
Use the labels and relationships in the model to explain the central idea.
Transfer the idea to a new example and justify the choice with evidence.
Apply the same relationship to the new context, then justify the answer using the labels and evidence shown.
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning.
Use the visual model to identify qualitative observation, then explain the important features.
Apply quantitative observation to a new example and compare the result.
Create an example using qualitative observation, quantitative observation and scaled instrument.
Core idea: Students learn to follow procedures to make and record observations, including making formal measurements using familiar scaled instruments and using digital tools as appropriate. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
Read the topic guide and use the teacher slide for instruction. Students can then use the worksheet for written work, open Practice for supported feedback, or take the Test when they are ready.

The SkillrHub lesson remains the primary learning resource. This optional video reinforces the explanation; you can complete the lesson and practice without watching.
Before you watch:
Crash Course Kids — Use a suitable instrument and record a measurement with its unit.
As you watch: Why would a measurement written as just 23 be incomplete?
Load video player Loads YouTube in this lesson. See the video notice below.
Try it: Measure one safe classroom object twice with a ruler. Record both measurements in centimetres and compare them.
