Biodiversity indices are the focus of this Grade 7 Science resource on Interactions and Ecosystems, helping students examine how biodiversity can be described and interpreted through richness, evenness, and habitat heterogeneity. Students connect biodiversity metrics with patterns of ecosystem resilience and function rather than treating biodiversity as a single measure.

What Students Explore

The resource develops key biodiversity concepts through concrete scientific reasoning. Students define biodiversity in terms of genetic diversity, species diversity, and ecosystem diversity, then compare what richness, evenness, and habitat heterogeneity can indicate about an ecosystem. The activities also ask students to interpret biodiversity metrics and relate observed patterns to ecosystem resilience and function.

This makes the worksheet useful for reinforcing biodiversity measurement, ecosystem analysis, and evidence-based scientific explanations within an Alberta Grade 7 science context.

Question and Activity Mix

Students work through multiple-choice questions, true/false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” section. The varied response formats give students opportunities to recognize key concepts, distinguish related biodiversity measures, interpret information, and communicate scientific reasoning in writing.

What You Receive

• Student worksheet focused on measuring biodiversity with indices
• Student Notes & Lesson Summary supplement for reinforcing the lesson concepts
• Separate Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Use

Use this Grade 7 biodiversity worksheet as guided practice after instruction, independent classwork, a review activity, or a written check of students' understanding of biodiversity concepts. The reading and written-response components also provide opportunities for students to support interpretations with evidence and explain relationships among biodiversity measures.

For teachers, the accompanying notes and lesson summary provide student-facing reinforcement, while the separate guide supplies practical prompts for instruction and discussion. Together, the materials support teaching species diversity, ecosystem diversity, biodiversity richness, evenness, and habitat heterogeneity within the Interactions and Ecosystems topic.
