Formulating Scientific Questions

Active learning helps Year 3 students grasp that scientific questions must be testable, not just curious. Hands-on sorting, refining, and building activities make abstract concepts concrete, turning 'I wonder if...' into structured inquiry.

Sorting Game: Scientific or Not?

Prepare cards with 20 everyday questions. In small groups, students sort them into 'scientific' or 'not scientific' piles and write one reason for each sort. Regroup as a class to share justifications and vote on borderline cases.

Differentiate what makes a question scientific rather than just a matter of opinion.

Facilitation Tip

During the Sorting Game, circulate and listen for students’ reasoning to identify who still confuses opinion with evidence.

What to look for

Present students with three questions: 'Do cats make good pets?', 'Does the amount of light affect how fast a plant grows?', and 'Is blue a prettier color than green?'. Ask students to circle the testable scientific question and explain why the others are not.

Observation Hunt: Question Makers

Take students on a 10-minute outdoor or classroom observation walk to note three phenomena, like dripping taps or leaf colours. Back inside, pairs turn each into a testable question and test one quickly with simple tools.

Analyze how we know if a question can be answered by an experiment.

Facilitation Tip

In the Observation Hunt, model how to turn an observation into a question aloud before students work in pairs.

What to look for

Show students a picture of a common object, like a bouncing ball. Ask them to write one observation about the ball and then formulate one testable scientific question based on that observation.

Question Relay: Refine and Pass

In lines of four, the first student writes a question from a prompt like 'magnets and paperclips'. The next improves it for testability, passes on; continue until the end. Groups present final versions.

Construct a testable question from a general observation.

Facilitation Tip

During the Question Relay, stand at the back to watch the flow of ideas without interrupting the peer feedback cycle.

What to look for

Start a class discussion with the observation: 'I noticed that when I water my plant every day, it seems to grow faster.' Ask students to work in pairs to turn this observation into two different testable scientific questions. Have pairs share their questions and discuss why they are testable.

Template Builder: Fair Test Questions

Provide sentence starters like 'Does [variable] affect [outcome] for [object]?'. Individually, students fill three from recent lessons, then swap with a partner for feedback on clarity and testability.

A few notes on teaching this unit

Start with simple examples students care about, like plants or toys, to build relevance. Avoid overemphasizing 'why' at the start, as 'what' and 'how' questions are often easier for Year 3 to test. Research shows that peer discussion and multiple drafting cycles improve question quality more than teacher correction alone.

Students will confidently distinguish testable scientific questions from untestable ones and rephrase vague questions into fair-test formats. Group work will show growing ability to justify choices and refine phrasing collaboratively.

Watch Out for These Misconceptions

• During Sorting Game: Scientific or Not?, watch for students who label all animal or plant questions as scientific.

  Prompt them to justify their choices aloud; if they cite opinion, guide them to re-read the question aloud and ask, 'Can we measure or observe the answer?'

• During Question Relay: Refine and Pass, watch for students who insist scientific questions must begin with 'why'.

  Hand them a 'why' question card and ask them to rephrase it to start with 'what' or 'does' in pairs before passing it on.

• During Observation Hunt: Question Makers, watch for students who claim that questions about the past cannot be investigated.

  Provide fossil or rock pictures and ask them to write a question like 'Do older rocks have more layers?' then model testing it using the image or a simulation.
