Problem-Solving for Environmental Issues (Science - 7th Grade)
Materials Needed
- Brainstorming paper divided in two columns
- Problem statement clearly displayed
- Timer
Preparation
Identify a problem students will solve. Frame the reverse question. Create two-column template: 'How to cause the problem' | 'Solution (reverse)'. Practice facilitation.
Step-by-Step Instructions
Present the problem: 'Our school cafeteria creates too much waste.'
Explain reverse brainstorming: Instead of solving the problem, we'll make it WORSE. Then we'll flip our ideas.
Reverse question: 'How could we make cafeteria waste as bad as possible?'
Brainstorm ways to cause maximum waste (5-7 min):
Use only non-recyclable materials
Make portions way too big so food gets thrown away
Don't have any recycling bins
Serve unpopular food no one will eat
Now flip each idea to a potential solution:
Use only compostable or recyclable materials
Offer smaller portions with option for seconds
Place clearly labeled recycling bins everywhere
Survey students about food preferences
Review solutions: Which are most practical? Most impactful?
This technique works because it's easier to think of how to cause problems - then solutions emerge naturally.
Star your top 3 solutions.
Groups share best ideas. Compile class solution list.
Extension: Create action plan for top solutions.
Differentiation Strategies
Model several reverse-to-solution examples. Work in pairs for brainstorming. For advanced students, apply to more complex or abstract problems.
Assessment Guidelines
Evaluate creativity in reverse brainstorming. Check that reversals are logical solutions. Look for novel ideas that wouldn't emerge from direct brainstorming. Note most promising solutions.
