Scientific inquiry and fair tests are at the heart of this Grade 6 Science worksheet on asking investigable questions, making predictions, and planning reliable investigations. Using a toy car experiment, students explore how to change one factor, measure an outcome, control other conditions, and collect evidence to evaluate a prediction.

🔬 From Scientific Questions to Fair Tests

The reading passage follows Nila as she investigates how different surfaces affect the distance a toy car travels. Students see how a scientific question leads to a prediction and how an investigation can be planned to produce useful evidence. The example introduces important scientific inquiry vocabulary in a practical context:

• Investigable questions: Identify questions that can be answered using observations and evidence.
• Predictions: Recognize predictions based on observations and consider whether results support them.
• Changed factors: Identify the independent factor deliberately changed during an investigation.
• Measured outcomes: Recognize the dependent factor and select suitable measuring tools.
• Controlled factors: Explain why conditions such as the toy car, ramp height, starting point, and release method should remain the same.
• Reliable evidence: Explore repeated trials, measurement records, and comparisons of results.
• Safety and ethics: Recognize precautions such as checking equipment stability, clearing the testing area, asking permission, and recording results honestly.

✏️ What Students Practise

Students work with the toy car investigation through multiple-choice questions, true-or-false statements, short-answer explanations, a labelled diagram, a categorizing activity, and a short note. They identify Nila's research question and prediction, distinguish changed and controlled factors, select an appropriate measuring tool, and explain why repeated measurements improve reliability.

The written responses also ask students to distinguish scientific questions from predictions, identify variables in a fair test, and suggest safety or ethical precautions. Together, these activities reinforce scientific investigation skills, evidence-based reasoning, and responsible communication of results.

🏫 Practical Classroom Uses

Use this scientific inquiry worksheet when introducing fair testing, reinforcing investigation vocabulary, or reviewing how scientists plan experiments and evaluate evidence. The toy car example gives students a consistent context for discussing variables before they plan or carry out investigations of their own. It can also support independent practice, small-group discussion, classroom review, or follow-up after an investigation.

Written for the British Columbia Grade 6 Science context, this resource brings together investigable questions, predictions, fair test conditions, measurement reliability, laboratory safety, and ethical scientific practice. The separate answer key and included teacher guidance make it easier to check responses and prepare focused discussions without needing to create additional supporting notes.
