This document outlines a project for biology students aged 14-15 to analyze data on healthy and unhealthy habits. The project has three steps: 1) students research and analyze data on nutrition, smoking, drinking and exercise in their country; 2) they share this information with students in another country to find commonalities and differences; 3) together they create a public campaign to increase awareness of healthy habits among teenagers. The project aims to involve students in their own learning about health while improving skills in math, English, digital literacy, and cooperation.
