Dry Ice Demonstration
In this National STEM Learning Centre and Network video, Simon Quinnell demonstrates an experiment using solid carbon dioxide (dry ice) and sodium hydroxide which is likely to impress students. The experiment can be used to talk about the properties of solids, liquids and gases, acids and alkalis or used as an open evening demonstration. The clip shows how solid carbon dioxide sublimes into gaseous carbon dioxide. The video is accompanied by an information sheet which summarises the requirements, procedure and scientific background to the experiment.
