The Project’s Guiding Question
How can we reduce our school’s environmental impact using science-based solutions?
Project Overview
Students investigate the environmental impact of their school by examining energy use, waste, water consumption, and biodiversity around the campus.
Throughout the project, students act as young environmental scientists. Their goal is to collect real data, identify sustainability challenges, understand the science behind them, and design realistic solutions that can improve the school environment.
The Final Product
The students will create a school sustainability proposal that presents practical, science-based recommendations for reducing the school’s environmental impact.
The final proposal should include:
- Data collected from the school environment
- Charts, graphs, or visual summaries of findings
- Scientific explanations of the problems identified
- Research-based sustainability solutions
- A realistic action plan for implementation
- A prototype, model, awareness campaign, or demonstration
- A presentation to school leaders, teachers, students, or the wider school community
Learning Goals
Students will:
- Understand how human activity affects the environment
- Collect, measure, organize, and analyze scientific data
- Investigate energy use, waste, water consumption, and biodiversity
- Explain environmental problems using scientific concepts
- Evaluate possible solutions based on evidence
- Design realistic sustainability improvements
- Communicate scientific findings clearly
- Collaborate on a real-life school challenge
- Reflect on their role as responsible environmental citizens
The Challenge
Students are expected to think like environmental scientists, not campaigners with slogans.
Their responsibility is not only to say that sustainability is important. They must investigate the school environment, collect evidence, analyze patterns, and propose realistic improvements based on science.
Students should understand that environmental problems are often connected. Energy use affects carbon emissions. Waste management affects pollution and resource use. Water consumption affects conservation. Biodiversity affects the health of local ecosystems.
When developing their sustainability proposal, students should continually ask:
- What environmental impact does our school currently have?
- What evidence do we have?
- What patterns can we identify from the data?
- What scientific concepts explain the problem?
- Which solutions are realistic for our school?
- What resources, costs, behaviors, or constraints must we consider?
- How can we persuade others using evidence rather than opinions?
Students should avoid suggesting general ideas that sound good but cannot realistically be implemented. Instead, they should create a practical proposal that fits the school’s actual needs, resources, and community.
The goal is not only to learn about sustainability, but to use science to improve the students’ own environment.
The PBL Recipe
Ingredients
- School energy data
- Waste samples or waste audit data
- Water use observations
- Biodiversity observations
- Scientific research
- Curiosity
- Critical thinking
- Environmental responsibility
- Creativity
- Collaboration
- Data analysis
Initiate
The students explore the concept of sustainability and examine how schools affect the environment. They discuss topics such as energy consumption, waste production, water use, recycling, pollution, school gardens, green spaces, and local biodiversity. Students walk around the school to observe possible sustainability challenges. They may look at classrooms, corridors, the cafeteria, outdoor spaces, bins, lighting, taps, gardens, and unused areas.
This phase concludes with a Project Kickoff, where student teams choose one sustainability focus area:
- Energy
- Waste
- Water
- Biodiversity
- School awareness and behavior change
Each team presents a short project pitch explaining the problem they want to investigate and why it matters.
Plan
The students design their investigation. They decide what data they need, how they will collect it, and how they will record it accurately. They choose research methods such as observations, measurements, surveys, waste audits, energy checks, water-use checks, or biodiversity mapping. They also research the scientific background of their topic, such as energy efficiency, waste, water conservation, ecosystems, pollution, or sustainable materials. Using this information, each team creates a simple work plan that includes roles, timeline, data collection methods, and success criteria.
Execute
The students collect and analyze data from the school environment. They organize their findings using tables, graphs, photos, maps, or infographics. Then they identify the main problem and explain it using scientific concepts. Based on their data and research, students design a realistic solution, prototype, campaign, or improvement plan. Their recommendation should connect clearly to evidence, science, and the school’s actual needs.
Deliver
The students present their sustainability proposal to an authentic audience, such as school leaders, teachers, students, parents, or community representatives. They explain the problem, the data they collected, the science behind their findings, and the solution they recommend. Their presentation should include clear visuals and, when relevant, a prototype, model, campaign material, or implementation plan.
Close
The students reflect on their work and evaluate how science helped them understand and address a real school challenge. They discuss what they learned, what surprised them, how data shaped their thinking, and what they would improve next time. They also consider how students can influence sustainability in their school and community.
