✅ Grade 8 Science | Energy Foundations Worksheet | Alberta Standard – Review the foundations of energy transfer and how it limits ecosystem processes.
✅ Grade 8 Science | Energy Efficiency Worksheet | Alberta Standards – Calculate and interpret energy efficiency to explain why ecosystems support different population sizes.
✅ Grade 8 Science | Density Effects Worksheet | Alberta Standards – Use density-related ideas to explain changes in resources and competition.
✅ Grade 8 Science | Consumers Hierarchy Worksheet | Alberta Standards – Organize consumer roles and justify hierarchy using interactions and evidence.

Skills & Standards

This Interactions and Ecosystems bundle is designed for Alberta Science by aligning practice to key expectations for understanding ecosystems as systems and for using scientific models to explain change. Students work with crosscutting concepts such as systems and system models, patterns, and energy and matter in living systems, while developing disciplinary core ideas related to interdependent relationships, population dynamics, nutrient cycling, and energy transfer. Multiple worksheets emphasize modeling, analytical reasoning, and evidence-based explanations so learners can justify claims using provided information, data, and cause-and-effect relationships rather than relying on memorization.

Perfect For

How to Use

Use the 15 worksheets as a lesson bundle across several class sessions (for example, 3–4 days per cycle of ecosystem interactions, then a second cycle for energy and systems modeling), and assign a short warm-up prediction question before students complete each worksheet; for differentiated support, pair modeling tasks with sentence stems for evidence-based explanations and extend with a quick “revise your model” step after reviewing answers.

Closing

Plan with confidence as students model ecosystems, analyze population and energy relationships, and communicate evidence-based explanations aligned to Alberta expectations.
