Overview

Biological Diversity and Conservation is the focus of this Grade 9 Science lesson bundle for Alberta classrooms, built around five ready-to-teach worksheets. Each resource guides students from big-picture conservation choices to the biology behind change in populations, including biodiversity, extinction, natural selection, reproduction, inheritance, and ecological relationships. With 5 total worksheets, the set supports a single, cohesive unit where learners analyze evidence, explain cause-and-effect, and connect organism traits to ecosystem outcomes within the Alberta framework.

Use the activities as a structured sequence for introducing concepts, practicing reasoning with examples, and checking understanding as students move from individual organisms to communities and habitats.

What's Included

• ✅ Biological Diversity and Conservation Decisions Grade 9 Science Worksheets – Students evaluate conservation options by linking biodiversity to ecological outcomes.
• ✅ Biodiversity and Extinction Worksheets | Grade 9 Science – Learners examine how extinction can occur and how loss of biodiversity affects ecosystems.
• ✅ Natural Selection and Cell Division Worksheets | Grade 9 Biology – Students connect cell division to growth and relate natural selection to trait survival.
• ✅ Reproduction and Inheritance: Grade 9 Biology Worksheets – Learners use reproduction and inheritance ideas to explain how traits can pass through generations.
• ✅ Ecological Niches and Symbiotic Relationships Worksheets Grade 9 – Students analyze ecological niches and symbiotic relationships to predict impacts on communities.

Skills & Standards

Aligned to Alberta expectations for science learning, this bundle emphasizes disciplinary thinking in biology: making sense of living systems, using evidence, and communicating scientific explanations. Students practice modeling cause-and-effect relationships between organisms and their environments, such as how changes in habitat and competition can influence survival. Across worksheets, learners build analytical reasoning by comparing examples (e.g., threatened species vs. stable populations) and by tracing how traits and inheritance can affect variation over time.

The set also supports evidence-based explanations: students justify claims using the biological concepts being studied rather than relying on memorization. Key unit skills include distinguishing biodiversity from extinction pressures, explaining natural selection with respect to traits and survival, connecting reproduction and inheritance to how characteristics persist or change, and applying niche and symbiosis ideas to interpret interactions within ecosystems.

Perfect For

• Teachers seeking structured instruction
• Sub plans
• Homework or review
• Intervention or centers
• Assessment preparation

How to Use

Plan for about 1–3 weeks to move through the worksheets in order: start with conservation decisions, then extend into biodiversity/extinction, follow with natural selection and cell division, and finish with reproduction/inheritance and ecological relationships. Try a brief warm-up each day using a short prompt tied to the worksheet’s focus (e.g., “What changes when biodiversity decreases?”). Use guided practice where students annotate explanations, then add exit tickets that ask for one claim and one piece of evidence from the worksheet activities. End the unit with a brief review that revisits how all concepts connect—from cells and traits to populations and ecosystems.
