My name is Mark Pulfer and currently I am a teacher of Chemistry and Environmental Systems and Societies in the IB program at Mulgrave School. However, I prefer to say that I am a teacher of science as I enjoy science in all of its different manifestations and have taught both Physics and Biology in the recent past. One of my joys in the classroom is to share recent discoveries with students and see the awe and wonder in their eyes. My primary focus these days is in Chemistry and I have taught IB Chemistry for 15 years. In this regard, I look forward to discussing the new changes to the curriculum with other colleagues.
