Plants for Food and Fibre gives Grade 7 Science students a practical introduction to investigating plant-growing methods, interpreting evidence, and evaluating improvements in food and fibre production. Designed around the Alberta science topic, this worksheet connects scientific investigation skills with real decisions about soil, water, seeds, and growing conditions.

Students explore how testable predictions, fair comparisons, careful measurements, and reliable evidence can help farmers and gardeners make informed decisions. Rather than treating investigation results as unquestionable facts, they consider uncertainty, alternative explanations, and limitations in the evidence.

What Students Explore

The reading passage introduces a bean plant growth investigation and explains how scientists can compare growing conditions while maintaining a fair test. Students apply these ideas to questions about water use, plant growth, investigation safety, and sustainable agricultural practices.

• Develop testable predictions about how watering affects plant growth.
• Plan safe investigations and identify factors that should remain consistent during a fair comparison.
• Interpret measurements recorded in tables or graphs and recognize possible sources of variation.
• Explain uncertainty, consider alternative explanations, and acknowledge limitations in results.
• Evaluate rainwater collection for irrigation by considering practical, environmental, and social consequences.
• Use reliable sources to support evidence-based scientific conclusions.

How Students Demonstrate Their Learning

The worksheet combines an informational reading passage with multiple-choice questions, true-or-false statements, short-answer responses, a labeled diagram, a categorization activity, and a short-note task. Students move from identifying scientific investigation principles to applying them in realistic plant-production scenarios.

Questions ask students to select a fair approach for comparing bean plants, recognize a testable prediction, explain why repeated measurements matter, and determine what to do when one plant grows differently from the others. Written responses extend the thinking by asking students to propose a prediction, explain a safety practice, reduce uncertainty, and assess a possible benefit and limitation of rainwater irrigation.
