Asking Scientific QuestionsActivities & Teaching Strategies
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.
Learning Objectives
- 1Classify observations about a natural artifact into categories of 'what I see' and 'what I wonder'.
- 2Formulate a testable question about a natural artifact that requires investigation beyond simple observation.
- 3Explain how asking 'why' or 'how' leads to scientific investigation.
- 4Identify similarities and differences between descriptive statements and investigative questions about natural objects.

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.'
Prepare & details
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.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
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?
Prepare & details
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.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
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.
Prepare & details
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.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
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.
What to Expect
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.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring 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.
What to Teach 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.
Common MisconceptionDuring Question Wall, watch for students who label every question as 'testable' because they think it means 'easy to answer.'
What to Teach Instead
Guide them to compare their questions to the definitions you provided and discuss why some questions need more evidence or tools.
Common MisconceptionDuring Think-Pair-Share, watch for students who assume their wonder questions have only one correct answer.
What to Teach Instead
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.
Assessment Ideas
After Mystery Object Investigation, give each student a picture of a different natural artifact. Ask them to write one observation and one investigative question, then highlight the verb in their question to assess their understanding of inquiry language.
During Question Wall, listen for students to categorize their questions correctly and explain their reasoning. Note who uses cause-and-effect language like 'why does this happen?' versus descriptive language like 'what is this?'
After Think-Pair-Share, provide two example questions about a shell: 'This shell is bumpy' and 'How do shells help animals survive?' Ask students to underline the question that requires investigation and add one detail that makes it testable.
Extensions & Scaffolding
- Challenge early finishers to write a set of three investigative questions about a new natural object not yet explored.
- Scaffolding for struggling students: Provide sentence starters like 'Why does this...?' or 'How does this...?' taped to their desks.
- Deeper exploration: Invite students to design a simple investigation plan for one of their questions using classroom tools like magnifiers or balance scales.
Key Vocabulary
| artifact | An object made by a person or found in nature that we can study. |

Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
