We aim to promote awareness of how engineering contributes towards sustainable development, through co-creating solutions to local environmental problems with children and showcasing their solutions on the high street. Through a series of interactive workshops facilitated by a diverse group of engineer volunteers. Children from local primary and secondary schools will learn how engineering shapes the world around them and use computer-aided design to propose solutions to address local sustainability challenges. The final designs will be presented and shared on social media, the company website, and in a playful participatory exhibition in retail shopping centres, which will be open to the public. This will allow members of the public to view models and animations of the children's final designs, respond to sustainability challenges, and learn more about the impact of engineering careers.
