Scientific inquiry and data analysis worksheets for Grade 6 Science help students examine how scientists interpret evidence, use models, and evaluate uncertainty in investigations. Built around Data, Models, and Scientific Uncertainty, this resource develops careful reasoning about what scientific data can show, what models leave out, and why conclusions must be supported by evidence rather than expectations.

Explore the reasoning behind scientific evidence

Students begin with an informational reading passage that introduces tables, graphs, scientific models, explanations, uncertainty, alternative possibilities, and bias. They consider how organizing measurements can reveal patterns without capturing every detail of a system, and why a model is useful even when it simplifies reality. The passage also emphasizes that unexpected results should be investigated rather than changed to fit a prediction.

These ideas carry into questions and activities that ask students to apply scientific reasoning to familiar investigation scenarios. Students interpret a graph showing plant growth, consider a claim about sunlight and plant height, and evaluate what to do when repeated measurements differ or results do not match an original prediction.

Skills and activities students practise

• Scientific data interpretation: Explain how tables and graphs organize measurements and help reveal patterns.
• Model evaluation: Identify why representations simplify complex systems and recognize their limitations.
• Evidence-based explanations: Connect scientific claims to observations and supporting evidence.
• Alternative explanations: Suggest other possibilities that could account for an observed result.
• Uncertainty and bias: Recognize limitations in measurements and identify how bias can affect an investigation.
• Investigation improvement: Explain how checking methods, gathering additional evidence, and repeating investigations can improve reliability without altering results.

The worksheet combines an informational passage, multiple-choice questions, true-or-false statements, short-answer responses, a labelled-diagram activity, a categorization task, and a short-note activity. This combination gives students opportunities to recognize key ideas, apply them to scenarios, explain their reasoning, and organize scientific information.

What is included

• Printable Grade 6 science worksheet focused on scientific inquiry, data, models, and uncertainty.
• Separate PDF answer key for checking student responses.
• Teacher Guide within the answer key PDF, including Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.
• Student Notes lines at the bottom of the worksheet for recording key ideas.

Practical classroom uses

Use this Grade 6 scientific investigation practice during a unit on scientific inquiry and communication, as guided classwork after discussing data and models, or as independent practice to review evidence-based explanations. The reading passage provides a shared starting point, while the questions allow students to demonstrate their reasoning in different ways. Short-answer prompts are especially useful for checking whether students can justify a claim, propose an alternative explanation, and recommend improvements to an investigation.

The separate answer key and included teacher guidance make preparation and response checking more straightforward. Student Notes lines also provide space for learners to capture important ideas for later review. The resource identifies British Columbia (BC) as its curriculum framework; no specific curriculum code is supplied.
