• 5-6 pieces of chart paper posted around the room
• Different colored markers for each group
• Environmental problem prompt cards
• Timer or bell for rotations
• Stickers for prioritizing ideas
• Environmental fact sheets for reference
• Summary recording sheet

Create chart paper stations around the room, each with a different environmental problem prompt at the top (e.g., 'Solutions for reducing plastic pollution,' 'Ways to conserve water at school,' 'How to protect endangered species'). Assign each student group a different color marker to track contributions. Prepare brief fact sheets about each environmental issue.

1. Introduction to carousel brainstorming (5 minutes):
2. Explain the rotation process and purpose of building on others' ideas
3. Establish norms: add new ideas, build on existing ones, no criticism during brainstorming
4. Demonstrate how to review, then add to previous contributions
2. Environmental issues background (8-10 minutes):
3. Briefly review the environmental problems featured at each station
4. Share key facts about each issue to inform brainstorming
5. Clarify that solutions can be individual, community, or global actions
3. First station rotation (5 minutes):
4. Assign each group to a starting station
5. Groups read the environmental problem prompt
6. Brainstorm and record as many solutions as possible using their assigned color marker
7. Aim for at least 5-7 ideas per station
4. Subsequent rotations (4 minutes each):
5. Groups rotate clockwise to the next station
6. Read all previous contributions
7. Add new ideas and build upon existing ones
8. Place a star next to ideas they think are especially effective
9. Continue until all groups have visited each station
5. Return to original station (5 minutes):
6. Groups return to their starting station
7. Review all contributions added during rotations
8. Organize the ideas into categories (e.g., low-cost, high-impact, school-based, home-based)
6. Gallery walk and prioritization (8 minutes):
7. Students tour all stations with dot stickers
8. Place stickers on the ideas they believe would be most effective and feasible
9. Note the top 3 ideas for each environmental problem
7. Solution action planning (10 minutes):
8. Groups select one top-rated solution from their original station
9. Develop a brief action plan: steps, resources needed, and potential obstacles
8. Sharing and reflection: Each group presents their environmental problem and top solution with action steps.

For younger students, use images alongside text prompts and simplify problems. For groups needing support, provide solution starter examples at each station. For advanced groups, add complexity with economic or political considerations for each solution.

Evaluate quantity and quality of contributions from each group. Note which students can effectively build on others' ideas versus simply adding unrelated suggestions. Review action plans for practicality and understanding of environmental issues.
