Core Skills Analysis
Design & Technology
C designed a prototype that measured both ecological and social footprints, selecting sustainable materials and documenting the production process. C applied the design cycle by researching impact, generating concepts, and iterating the model based on feedback. The activity helped C understand how design choices affect resource use, waste, and community well‑being. By presenting a finished prototype, C demonstrated the ability to communicate technical information clearly.
Science
C investigated the scientific principles behind carbon emissions, water usage, and biodiversity loss, calculating the ecological footprint of everyday items. C recorded data from online calculators and performed simple experiments to measure energy consumption. This work reinforced concepts of energy transfer, life‑cycle analysis, and the scientific method. C also reflected on how scientific data can inform responsible consumption.
Geography
C mapped the geographic distribution of resources used in the prototype, linking local production to global supply chains. C examined how different regions experience social impacts such as labor conditions and environmental degradation. By interpreting maps and spatial data, C learned how place‑based factors shape ecological and social footprints. The activity highlighted the interconnectedness of human activity and the planet.
Citizenship
C evaluated the social implications of material choices, considering fair‑trade principles, community health, and ethical sourcing. C discussed how individual consumer decisions influence societal equity and corporate responsibility. This analysis deepened C's understanding of rights, duties, and sustainable citizenship. C also practiced persuasive argumentation when presenting recommendations for more ethical alternatives.
Mathematics
C collected quantitative data on energy use, waste generation, and labor hours, then applied percentages, ratios, and basic statistics to compare alternatives. C created bar charts and pie graphs to visualise the relative size of ecological versus social impacts. These calculations strengthened C's ability to interpret numerical information and draw evidence‑based conclusions. The activity also introduced C to real‑world problem‑solving using mathematical reasoning.
Tips
1. Conduct a field visit to a local recycling centre or community garden and record real‑world data on waste and resource flows. 2. Organise a debate where C and peers argue the merits of different material choices, using the footprints calculated as evidence. 3. Extend the project by designing a low‑impact product for school use, documenting every step in a digital portfolio. 4. Integrate a reflective journal where C links personal lifestyle choices to the footprints studied, encouraging long‑term sustainable habits.
