Asking Scientific Questions

Children learn science best when they play the role of investigators, not just observers. This topic turns natural objects into tools for curiosity by making questions the focus of every interaction. Active exploration helps students move beyond naming things to wondering why and how they work.

Activity 01

• Mystery Object
• 25 min · Small Groups

Mystery Object Investigation

Place a natural artifact (pine cone, dried seed pod, feather, piece of pumice) on each table. Students observe using their senses, write or draw two things they notice and one question they have. Groups then share questions and the class sorts them into 'we can find out by testing' and 'we need to look it up.'

Analyze what you notice about this mystery object.

Facilitation Tip

During Mystery Object Investigation, hold up each object and pause to let students quietly observe for 15 seconds before asking any questions.

What to look for

Give each student a picture of a natural artifact (e.g., a leaf, a rock). Ask them to write down one thing they 'notice' and one thing they 'wonder' about it. Then, ask them to turn their 'wonder' into a question that needs an investigation.

Question Wall: Testable vs. Research Questions

After a free exploration session with natural materials, students write or dictate one question each on a sticky note. Post all questions on the wall and guide the class to sort them together: which questions could be answered by doing an experiment right here, and which would need a book or a scientist to answer?

Explain how we can find the answer to a question we have about nature.

Facilitation Tip

For Question Wall, model how to label a question as 'testable' or 'research-based' by thinking aloud as you categorize your own example.

What to look for

Present a pine cone. Ask: 'What do you notice about this pine cone?' Record student observations. Then ask: 'What questions do you have about this pine cone that we can't answer just by looking?' Guide students to formulate investigative questions like 'Why do pine cones open and close?'

Activity 03

Think-Pair-Share: Asking Better Questions

Present two versions of a question: 'Is this rock big?' versus 'Does the color of a rock tell us where it came from?' Ask pairs to discuss which question is more interesting to investigate and why. Guide students toward recognizing that testable, open questions produce more learning than yes/no ones.

Construct a question about an object that requires an investigation to answer.

Facilitation Tip

In Think-Pair-Share, assign partners randomly to encourage diverse perspectives and prevent echo chambers of similar ideas.

What to look for

Provide students with two example questions about a feather: 'This feather is brown' and 'Why do birds have feathers?' Ask students to circle the question that would require an investigation to answer and explain why.

A few notes on teaching this unit

Teachers succeed with this topic when they normalize uncertainty and celebrate curiosity over correctness. Avoid rushing to answers; instead, frame questions as invitations for future learning. Research shows that young children develop stronger inquiry skills when adults model wonder and patience rather than immediate solutions.

By the end of these activities, students will consistently turn observations into investigative questions and recognize the difference between descriptive and inquiry-based questions. Their questions should show curiosity about processes, causes, and functions, not just appearance.

Watch Out for These Misconceptions

• During Mystery Object Investigation, watch for students who say 'I don't know what this is,' and gently redirect them to ask 'What could we find out about this object?' instead.

  Use the object's unfamiliarity as a chance to practice question stems like 'Why might this...?' or 'What would happen if...?' to build comfort with not knowing answers.

• During Question Wall, watch for students who label every question as 'testable' because they think it means 'easy to answer.'

  Guide them to compare their questions to the definitions you provided and discuss why some questions need more evidence or tools.

• During Think-Pair-Share, watch for students who assume their wonder questions have only one correct answer.

  Prompt them to ask follow-ups like 'What else could we notice?' or 'How might someone else see this differently?' to reinforce multiple valid perspectives.
