Categories: General InterestBeing aware of best practices in the use of chemicals is essential for maintaining safe and engaging science programs in secondary schools. This document was developed to alert teachers to the hazards posed by certain chemicals and provides guidance on their... read more
Categories: General InterestIn science, hands-on activities are always desirable, particularly when these are real time, actual experimentation, not just virtual simulations. This conflicts with our current reality: budget cuts; safety concerns in overcrowded classes; other demands on teacher... read more
Categories: General InterestThis article provides some recommendations for: storing flammable liquids; the quantities to be kept in schools; the types of storage cabinets usable; and the need to vent those cabinets. Such venting would neither violate the Ontario Fire Code, nor compromise the ULC... read more
Categories: General InterestA chemistry teacher was demonstrating a reaction between sulfur and zinc. The powdered sulfur and zinc were mixed in a test tube and heated in a fume hood. Usually this produced a minor explosion out of the top of the test tube. However, this time the explosion... read more
Categories: General InterestIt is the responsibility of all those working in a laboratory to be aware of potential hazards and to prevent them from becoming accidents. However, whenever chemicals are in use, there is a danger of spillage. A well-organized science program will have available a... read more
Categories: General InterestMy practice teaching took place in the United Kingdom at a secondary school whose students had more than their fair share of social and behavioural problems. We delivered a laboratory based science program, with many experiments for the students. My unit on... read more
Categories: General InterestI was in second year co-op chemistry at the University of Waterloo. The class was inorganic chemistry, and we were synthesizing some organometallic compound. This was one of those laboratories where special caution was urged throughout the experiment. It was near the... read more
