Stacyann Codner (Redcoat Teacher) is a passionate science educator with more than a decade of experience teaching KS3 and GCSE Science in both UK and Caribbean secondary schools. With a BSc in Education, a double major in Biology and Chemistry, and experience as a former GCSE AQA examiner, she offers unique insight into what examiners expect and how to help students succeed.

Her resources are carefully designed to strengthen scientific vocabulary, build critical thinking skills, and link science to real-world applications for deeper understanding.
