The Scientific Method: Question and Hypothesis

Active learning lets students practice the scientific method in real time, turning abstract concepts into concrete skills. By working in pairs, small groups, and whole-class settings, students see how questions and hypotheses shape investigations, making the process visible and memorable.

Activity 01

• Inquiry Circle
• 25 min · Pairs

Pairs: Observation to Hypothesis Chain

Partners select a classroom phenomenon, like pencil dissolving in water. One writes a testable question; the other adds an 'If...then...because...' hypothesis. They chain three more, refining each for clarity. Pairs share chains class-wide.

Differentiate between a scientific question and a non-scientific question.

Facilitation Tip

During Observation to Hypothesis Chain, circulate and prompt pairs with 'What change are you testing?' to keep their focus on variables.

What to look for

Present students with three scenarios: a scientific question, a non-scientific question, and a statement of opinion. Ask them to label each and write one sentence explaining their choice for the scientific question.

Small Groups: Question Sorting Carousel

Prepare cards with 20 questions, half scientific, half not. Groups sort into categories, justify choices, then rotate to review and debate prior sorts. Conclude with class vote on trickiest items.

Construct a testable hypothesis for a given observation.

Facilitation Tip

For Question Sorting Carousel, set a timer for each station so groups move efficiently while debating testability.

What to look for

Provide students with an observation, such as 'Plants in sunlight seem to grow faster than plants in shade.' Ask them to write one testable question and one corresponding hypothesis for this observation, identifying the independent and dependent variables.

Activity 03

• 35 min · Whole Class

Whole Class: Hypothesis Peer Review Gallery

Students write hypotheses for provided scenarios on posters. Gallery walk: view others, add sticky-note feedback on testability. Writers revise based on notes and present improvements.

Critique a hypothesis for its clarity and falsifiability.

Facilitation Tip

In Hypothesis Peer Review Gallery, ask students to leave written feedback using sentence starters like 'I notice...' and 'Have you considered...' to guide constructive critique.

What to look for

Students write a hypothesis for a given scientific question. They then swap hypotheses with a partner. Each student critiques their partner's hypothesis, answering: Is it clear? Can it be tested? Is it falsifiable? Partners provide feedback on one specific area for improvement.

Activity 04

• 30 min · Individual

Individual: Falsifiability Quick-Fire

Give observation prompts. Individually draft hypotheses, then pair to check if falsifiable by proposing disproof tests. Regroup to share strongest examples.

Differentiate between a scientific question and a non-scientific question.

Facilitation Tip

For Falsifiability Quick-Fire, model one example aloud before students write to set clear expectations for structure and reasoning.

What to look for

Present students with three scenarios: a scientific question, a non-scientific question, and a statement of opinion. Ask them to label each and write one sentence explaining their choice for the scientific question.

A few notes on teaching this unit

Teaching scientific questions and hypotheses works best when students actively build and revise their own work. Avoid giving answers upfront; instead, use structured peer feedback to let students discover clarity and testability. Research shows that students grasp falsifiability more deeply when they critique others’ hypotheses, so include time for debate and counter-evidence.

Students will confidently distinguish testable scientific questions from opinion-based ones and frame hypotheses using 'If...then...because...' to predict outcomes. They will also critique each other’s work, showing they understand falsifiability and clear variable identification.

Watch Out for These Misconceptions

• During Observation to Hypothesis Chain, watch for students writing vague statements like 'The plant will grow bigger.'

  Have pairs check their hypotheses against the 'If...then...because...' format and revise until each part is specific and testable, then test a mini-version to see if the prediction holds.

• During Question Sorting Carousel, watch for groups labeling all 'why' questions as scientific.

  Direct groups to rephrase 'why' questions into testable forms, such as changing 'Why do leaves change color?' to 'What temperature triggers leaf color change?' for sorting accuracy.

• During Hypothesis Peer Review Gallery, watch for students assuming hypotheses must be proven correct.

  Ask students to add a second hypothesis that could disprove the first, then present both in the gallery for class debate on falsifiability.
