Measurement and data analysis are essential science investigation skills for Grade 6 students. This Science worksheet develops students’ ability to record measurements with appropriate SI units, calculate the mean of repeated trials, choose useful data displays, and evaluate evidence before drawing conclusions. It connects measurement skills with realistic examples, including a toy car investigation and changes in plant height over time.

From Raw Measurements to Reliable Evidence

Students explore the difference between observations and numerical measurements, why units matter, and how repeating trials can reveal variation. The reading passage introduces metres, seconds, grams, and kilograms, then demonstrates how to calculate a mean from repeated distance measurements. It also explains how tables, line graphs, and scatter plots help scientists organize results and examine patterns or relationships between variables.

Beyond calculations, students consider the quality of scientific evidence. They examine possible measurement errors, decide how to respond to an unusual result, and recognize why an investigation’s conclusion should reflect the available data and its limitations.

Skills Practised in the Worksheet

• Measurement and SI units: identify appropriate tools and units for measuring length and time, and recognize practices that can cause errors.
• Repeated trials and mean: calculate the average of measurements and explain how repeated trials help reveal variation.
• Data displays: select a line graph for changes over time and a scatter plot for investigating relationships between measured variables.
• Evidence-based reasoning: evaluate unusual results, suggest ways to improve measurement reliability, and describe conclusions supported by the data.

Students apply these concepts through multiple-choice questions, true-or-false statements, short-answer calculations and explanations, a labeled diagram activity, a categorization task, and a short-note activity. The tasks move from recognizing measurement principles to using calculations and evidence to justify scientific reasoning.

What Is Included

• Printable Grade 6 Science worksheet focused on measurements, repeated trials, and data displays.
• A separate PDF answer key for checking student responses.
• Student Notes lines at the bottom of the worksheet for recording key ideas.
• A Teacher Guide inside the Answer Key PDF, including Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Practical Classroom Uses

Use this measurement and data analysis practice during a unit on scientific investigations, as guided practice after introducing SI units and mean calculations, or as independent review of data interpretation. It can also support discussion after students collect their own measurements in a classroom investigation. The toy car examples provide a context for considering how ramp height may relate to distance travelled, while the plant-height scenario reinforces choosing a display that shows change over time.

Designed for the Texas Science 6: Investigations, Evidence and Systems topic, this resource gives students structured practice with core investigation skills and provides teachers with a separate answer key and practical guidance for reviewing student thinking.
