Habitat fragmentation and ecosystem connectivity take center stage in this Grade 6 Science resource focused on biodiversity within an Ontario framework. Students examine how breaking habitats into separate patches can change connectivity, movement, species interactions, and the long-term persistence of local biodiversity.

Why This Topic Matters

The resource moves beyond simply defining habitat fragmentation. Students explore how habitat patches and corridors influence ecological connections, then consider what happens when those connections become weaker. They examine effects on gene flow, pollinator movement, and species interactions, helping connect habitat structure with biodiversity over time.

Students also work with metrics used to evaluate fragment size and corridor value and evaluate how fragmentation may affect whether local biodiversity persists in the long term. The focus on connectivity gives learners a way to reason about how changes to habitat structure can influence living communities.

What Students Practice

• Explain how habitat fragmentation changes connectivity between habitat patches.
• Describe how fragmentation can affect gene flow, pollinator movement, and species interactions.
• Identify metrics used to evaluate fragment size and corridor value.
• Evaluate long-term impacts of fragmentation on local biodiversity persistence.

The habitat fragmentation worksheet combines multiple-choice questions, true-false questions, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” element. This range gives students opportunities to recognize concepts, explain ecological relationships, and justify ideas in writing.

Included for Teachers and Students

• ✅ Student worksheet covering habitat fragmentation and ecosystem connectivity
• ✅ Separate PDF answer key for checking student responses
• ✅ Student Notes & Lesson Summary supplement for reinforcing key ideas
• ✅ Separate Teacher Guide with learning objectives, teaching tips, discussion questions, and common mistakes

Classroom Use

Use this Grade 6 biodiversity activity as guided practice after instruction, independent science work, review, or a structured opportunity for students to apply ecological concepts in writing. The included Teacher Guide provides discussion questions and identifies common mistakes, making it easier to address misconceptions while students work through habitat connectivity and fragmentation.

For teachers building an ecosystem and biodiversity unit, the resource provides a focused way to connect habitat structure with ecological processes. Students are asked not only to identify what fragmentation is, but also to reason about its consequences for movement, interactions, and biodiversity persistence.

Ontario framework: This resource is identified for Grade 6 Science within an Ontario framework and provides focused practice around biodiversity, habitat fragmentation, and ecosystem connectivity.
