Overview

---

Ecosystems & Land Use Decisions is a Grade 7 ecosystems lesson bundle for Alberta Science, with 5 worksheets that guide students to use observations and evidence when analyzing ecosystems. Across the bundle, learners connect habitats, food webs, and matter cycling to real choices about environmental impact and land use. Students also practice interpreting ecological change and making reasoning-based decisions grounded in what happens to organisms and ecosystems over time.

What's Included

---

• ✅ Ecosystem Investigations and Evidence-Based Decisions Worksheet Grade 7 – Establishes an investigation routine and asks students to justify ecosystem decisions using evidence.
• ✅ Environmental Choices and Ecosystems Worksheet | Grade 7 Science – Connects everyday environmental choices to ecosystem effects, helping students predict outcomes.
• ✅ Ecological Change and Habitat Observations Worksheet Grade 7 Science – Focuses on habitat observations and patterns of ecological change over time.
• ✅ Food Webs and Matter Cycles Worksheet | Grade 7 Ecosystems Science – Builds links between food webs, energy flow, and matter cycling in ecosystems.
• ✅ Habitat and Land Use Decisions Worksheet for Grade 7 Science – Supports students in evaluating land use scenarios and selecting decisions that protect habitats.

Skills & Standards

---

In line with Alberta’s science approach, this Grade 7 bundle emphasizes investigating systems, using evidence to form explanations, and communicating reasoning. Students work with core ecological ideas by examining how living things interact within habitats and how ecosystems change. They practice evidence-based claims by linking observations (such as habitat features and ecosystem patterns) to conclusions about ecosystem impacts. The activities also strengthen modeling and analytical reasoning through food web interpretation and by tracing how matter cycles through ecosystem components. Throughout, students learn to explain cause-and-effect relationships: how changes to habitat conditions or environmental choices can alter population interactions, ecological stability, and the availability of resources.

Perfect For

---

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

How to Use

---

Use this single unit across about 1–3 weeks, depending on your schedule. Start with the evidence-based routine in the first worksheet, then move through environmental choices and habitat observations before students integrate food web and matter cycle thinking. Suggested pacing includes: (1) a short warm-up each day using one question from the current worksheet as a review prompt, (2) guided practice where students highlight evidence lines before answering explanation questions, and (3) end-of-unit exit tickets that ask students to justify a land use or environmental decision using at least two supporting ideas from the bundle.
