Finding Solutions

Overview

Students examine local or familiar environmental issues, identify contributing causes and impacts, and work collaboratively to design feasible solutions. They then present their proposals and reflect on evidence and trade-offs.

Learning intentions

• Students will be able to identify environmental issues and describe their impacts on living things and the environment.
• Students will be able to suggest and justify solutions using scientific thinking.
• Students will be able to evaluate how different solutions may affect the environment and society.
• Students will be able to communicate their ideas clearly in a group presentation.

Success criteria

• I can name an environmental issue and explain at least two causes and two effects.
• I can propose a solution that is realistic and includes what would change in the environment.
• I can justify my solution using relevant evidence or logical scientific reasoning.
• I can clearly present my group’s plan and respond respectfully to questions.

Curriculum links

• Evidence-based science inquiry and communication (reasoning from observations/data)
• Earth and Space Science expectations: human impacts on the environment and environmental sustainability
• Critical thinking about solutions: predicting outcomes and considering trade-offs
• Scientific and environmental literacy: communicating findings for a real-world audience

Lesson structure ({total minutes})

1. 0–5 min: Warm-up prompt and quick share Display one short scenario (e.g., litter in a park, river pollution, heat islands). Students write a 1–2 sentence answer: “What environmental issue is happening, and who is affected?” Volunteers share.

2. 5–10 min: Mini-lesson—Issue to Solution Briefly model a thinking routine:

• Issue: what is happening?
• Cause: why is it happening?
• Impact: what changes for living things and ecosystems?
• Solution: what action could reduce the problem? Emphasize that solutions should be justified with evidence or science reasoning and include possible trade-offs.

3. 10–20 min: Group assignment and planning Put students into groups of 4–5. Each group chooses an issue card (or teacher-approved option) such as waste management, water quality, habitat loss, air pollution, or invasive species. Groups complete a planning sheet with: issue summary, causes/effects, and a proposed solution with justification.

4. 20–30 min: Solution design—evidence and feasibility Groups brainstorm at least two solution components (e.g., prevention, monitoring, cleanup, policy/community action). They must include:

• How it reduces the issue (mechanism)
• Who would participate (individuals, school, community)
• One potential challenge or trade-off and how to address it Teacher circulates using guiding questions and prompts.

5. 30–38 min: Presentations (gallery-style or short rounds) Each group presents for about 2 minutes, followed by a 30-second question from another group. Peers use a simple checklist to listen for: clear issue, explained impacts, and justified solution.

6. 38–43 min: Reflection—What would we measure? Individually, students write: “If we tried this solution, what could we measure to know it worked?” Examples: number of waste items collected, turbidity readings, biodiversity observations, air quality indicators.

7. 43–45 min: Exit ticket Students submit one “I can…” statement: either identifying the issue and impacts OR explaining a solution and justification.

Resources

• Environmental issue scenario cards (print or displayed)
• Group planning sheet: Issue–Cause–Impact–Solution–Trade-offs–How we’d measure success
• Presentation roles (speaker, evidence checker, timekeeper, reporter)
• Peer listening checklist for presentations
• Short teacher-provided example of a well-justified solution (one paragraph or infographic)
• Markers, chart paper or digital slide template
• Exit ticket slips
• ESL-friendly sentence starters (e.g., “The environmental issue is…”, “It affects… because…”, “A possible solution is…”)

Assessment

• Formative: Teacher observation during group planning using guiding questions about cause/effect and justification.
• Summative (mini-performance): Group presentation assessed with a rubric-style checklist (clear issue, impacts, justified solution, trade-offs).
• Individual reflection: Exit ticket and “What would we measure?” response to check understanding of evidence and evaluating solutions.

Differentiation

• Support (Scaffolds): Provide sentence starters and a completed model frame for one example issue. Offer a word bank (issue, causes, impacts, reduce, protect, measure, evidence).
• Support (Choice): Allow groups to select from multiple issue cards at varying complexity and provide optional “starter” cause/effect options.
• EAL learners: Permit first-draft planning in home language notes, then require final responses in English. Provide extra time and structured roles so each student has a task.
• SEN/Additional needs: Break planning into smaller steps with checkboxes on the planning sheet (not on slides). Offer an option to present in a pair with a support partner and provide a graphic organizer rather than open writing.
• Extension (Higher challenge): Require students to compare two solutions using criteria (cost, time, effectiveness, environmental impact) and predict which would be most effective for a specific community.
