The BEST project aims to equip teachers with biomimicry-based STEM education tools, fostering sustainability-focused learning. It seeks to create a network of trained Biomimicry Expert Teachers (BETs) across five European countries, integrate biomimicry into STEM curricula, and provide professional development. The project aspires to enhance students' problem-solving skills, increase girls' participation in STEM, and support educators with innovative, solution-focused teaching methods.
