SDGs in the classroom: how to bring the Sustainable Development Goals into science

The 2030 Agenda and its 17 Sustainable Development Goals are the global reference framework for a fairer future. School is where they should stop being just a poster on the wall.
Beyond painting a mural
It's common for the SDGs to be worked on symbolically: the 17 little squares on a mural, a manifesto read out on Peace Day. It generates goodwill, but it doesn't change much. For them to have real impact, they need to be integrated into STEM subjects at curriculum level, using data students have collected themselves.
Three STEM projects aligned with the SDGs
SDG 6: Clean Water and Sanitation
The project: study the water cycle and the school's consumption. With a properly calibrated soil moisture sensor, students can design a rainwater collection and filtering system for the school garden, and compare how much tap water is saved compared to traditional watering over a month.
SDG 11: Sustainable Cities and Communities
The project: analyze the "route to school." With the DS18B20 external temperature probe, students measure the temperature difference between unshaded pavements and tree-lined routes along different stretches of their usual commute, and present a "safe, cool route to school" proposal based on that data, not intuition.
SDG 13: Climate Action
The project: monitor classroom temperature and light for a week to detect when the heating or artificial lighting is on without real need (for example, when there's enough natural light, or outside class hours), and calculate how much energy would be saved by correcting those habits over the school year.
Data for activism, not just opinion
STEM education gives students something more valuable than good intentions: the ability to defend a climate position with their own data, not just slogans. A teenager who has measured, calculated and presented a report argues differently from one who has only heard about the problem.
The SDG 11 project uses the same DS18B20 probe as the article on heat islands and school microclimates, where it's developed step by step. And if you're looking for more project ideas by subject, these 5 PBL examples for secondary school go in the same direction.
