The "droso4schools" project aims to introduce the fruit fly "Drosophila" as a powerful modern teaching tool to convey curriculum-relevant specifications in biology lessons. Flies are easy and cheap to breed and have been at the forefront of biology research for a century, providing unique conceptual understanding of biology and exciting, memorable experiments that reflect relevant contemporary research. To provide adequate resources, PhD students worked as teaching assistants in partner schools to develop and test free-to-download sample lessons with support materials, two educational "YouTube" videos and a dedicated "droso4schools" website providing resources for lesson preparation, homework tasks and revision.
