I have been teaching IB MYP Science and IBDP Biology for over 20 years in a variety of international schools around the world. I am an IB examiner and I mark IB Biology Extended Essays and IB Biology SL Paper 2 examinations. I have made many resources to aid teaching and learning for the IB Diploma Biology and IB MYP Science courses. Now I am sharing these resources with you. I believe in that Science allows students to understand the world around them and take meaningful action for the future.
