Overview

Ecosystems and biodiversity drive this Grade 7 Holiday Science lesson bundle, aligned to May standards and designed for dependable classroom pacing. With 2 ready-to-use worksheets, students practice reading ecological systems, identifying changes, and explaining their thinking with evidence 🌿.

What’s Included

• ✅ Grade 7 Science | Protecting Ecosystems Worksheet (May standards) PDF – Students examine ecosystem impacts and use cause-and-effect reasoning to describe what protection efforts can support.
• ✅ Grade 7 Science | Biodiversity Roots Worksheet (May Standard) PDF – Students connect biodiversity to ecosystem stability and justify claims using information from the worksheet prompts.

Skills & Standards

These Grade 7 Holiday Science activities are structured around May standards and focus on crosscutting concepts such as systems and system models and cause and effect. Students address disciplinary core ideas related to ecosystems, biodiversity, and how interactions among organisms shape stability and resilience. Each worksheet includes short-response and evidence prompts that support modeling (describing relationships within an ecosystem), analytical reasoning (organizing claims and selecting relevant details), and evidence-based explanations (using provided information or observations to support conclusions).

Perfect For

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

How to Use

Use this lesson bundle in a multi-day sequence: complete “Protecting Ecosystems” first (1 day), then follow with “Biodiversity Roots” (1 day) to build from ecosystem impacts to biodiversity’s role in stability. For each day, preview the learning target, have students complete the worksheet independently or with guided small groups, and then use a brief share-out to record one evidence-based explanation on a class anchor chart. If you need centers or intervention, assign one worksheet per station and provide sentence stems for claims (e.g., “The ecosystem changes because…” and “Biodiversity matters because…”). For assessment preparation, collect responses as a quick check for understanding and use the results to group students for targeted reteaching the next day.
