Overview

---

Biodiversity is central to Grade 6 Science, and these 15 Ontario worksheets help students make sense of how living things interact across habitats and ecosystems 🌿. Use this Ontario framework-aligned custom unit resource to support clear reading, reasoning, and evidence-based discussion while students build from classification to ecosystem relationships.

Skills & Standards

---

This biodiversity science resource naturally supports the Ontario framework by engaging students with crosscutting concepts such as systems and cause and effect. Students work with disciplinary core ideas related to ecosystems and interactions, using modeling (food webs, habitat impacts, population shifts) to strengthen analytical reasoning. Throughout, tasks call for evidence-based explanations using data, observations, and organism relationships to justify claims about biodiversity.

Perfect For

---

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

How to Use

---

Plan a multi-day pacing cycle by grouping worksheets into themes: classification and traits first, then adaptations and population/niche ideas, followed by ecosystem relationships like keystone species, invasive species, habitat fragmentation, and food webs. Try 2–3 worksheets per class period with a brief discussion, then assign one page as review or center practice. Use the answer keys for fast checks, small-group reteaching, and targeted homework support.
