Overview

Grade 7 Science students explore ecosystems and biodiversity through the Alberta-aligned “Ecosystems and Biodiversity” unit. This Lesson Bundle includes 15 worksheet-based lessons that support ecological thinking—from wetlands and population factors to food webs, conservation status, and adaptation traits—while building inquiry routines used across the Alberta science program.

Because ecosystems are interconnected systems, learners practice using evidence to explain how biotic and abiotic components interact, how populations change over time, and why biodiversity matters for ecosystem stability and sustainability.

What's Included

• ✅ Wetland Functions Worksheet | Grade 7 Science Activities – Students analyze how wetlands support habitat, water quality, and ecosystem services.
• ✅ Population Factors Worksheet | Grade 7 Science Practice – Learners identify variables that influence population growth and decline.
• ✅ Symbiosis Types Worksheet | Grade 7 Science Activities – Students classify mutualism, commensalism, and parasitism using real examples.
• ✅ Pollution Effects Worksheet | Grade 7 Science Activities – Learners connect pollutants to changes in organisms and ecosystem balance.
• ✅ Monitoring Methods Worksheet | Grade 7 Science Activities – Students compare observation and data-collection approaches for tracking change.
• ✅ Modelling Ecosystems Worksheet | Grade 7 Science Practice – Learners build models to represent relationships within an ecosystem.
• ✅ Migration Patterns Worksheet | Grade 7 Science Activities – Students interpret factors that drive seasonal movement and habitat use.
• ✅ Levels Of Organization Worksheet Pack | Grade 7 Science Activities – Learners order and connect ecosystem levels from organisms to biomes.
• ✅ Indigenous Knowledge Worksheet | Grade 7 Science Activities – Students reflect on how Indigenous knowledge can inform environmental understanding.
• ✅ Food Webs Worksheet | Grade 7 Science Activities – Learners map feeding relationships and predict impacts of changes.
• ✅ Ecological Inquiry Worksheet | Grade 7 Science Activities – Students practise forming questions, selecting evidence, and justifying conclusions.
• ✅ Conservation Status Worksheet | Grade 7 Science Activities – Learners examine categories of risk and what they imply for action.
• ✅ Biotic Abiotic Worksheet | Grade 7 Science Activities – Students distinguish living and non-living factors and explain how they interact.
• ✅ Biodiversity Measures Worksheet | Grade 7 Science Practice – Learners apply measures that help quantify biodiversity in habitats.
• ✅ Adaptation Traits Worksheet Pack | Grade 7 Science Activities – Students evaluate trait-based adaptations and how they support survival.

Skills & Standards

Aligned with the Alberta science emphasis on inquiry and scientific reasoning, this unit strengthens:

• Systems thinking: viewing ecosystems as interacting components (biotic and abiotic) with cause-and-effect relationships.
• Modeling and analysis: using ecosystem models and food webs to interpret interactions and predict outcomes when conditions change.
• Evidence-based explanation: using data from monitoring scenarios to support claims about population and ecosystem change.
• Inquiry skills: asking ecological questions, selecting appropriate evidence, and communicating reasoning clearly.
• Ecology-specific competencies: identifying population factors, classifying symbiosis types, interpreting migration influences, and connecting biodiversity measures to ecosystem resilience.

Across the activities, students practise making claims about ecosystems and biodiversity that are supported by observations, scientific vocabulary, and structured explanations—skills that fit naturally with classroom science routines.

Perfect For

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

How to Use

Plan for 1–3 weeks of focused instruction for this single unit. A common pacing is to introduce core concepts (wetlands, biotic/abiotic factors, levels of organization) early, then progress toward interactions (symbiosis, food webs, pollution effects), and finish with application and evaluation (monitoring, conservation status, biodiversity measures, adaptations).

• Use a short daily warm-up where students connect a real-world observation (local habitat, media example, or scenario) to one worksheet prompt.
• Pair guided practice with modelling tasks (ecosystem and food web worksheets), then have students complete an exit ticket predicting how change affects organisms.
• Run an end-of-unit review using the ecological inquiry worksheet to consolidate how students ask questions, support claims, and explain their reasoning about ecosystems and biodiversity.
