| My name is Tahir Elfitori and I am a grade 8 student at Champlain Discovery Public School in Pembroke, Ontario. I am the oldest child of four children, and have a younger sister and twin brothers. My experience at the CWSF last year left such a great impression. Prior to this experience, I never realized that there were so many great opportunities in science. My favourite subjects in school are Science, Math and History. I also really enjoy sports. I speak two languages, English and Arabic and travel to Ottawa every Saturday to attend Arabic school. My future ambitions include pursuing a career in science as a Surgeon. |
