A science experiment sent Bethel High School students home early yesterday when the sprinkler system was set off. The chemistry experiment led to a small fire, and the sprinklers flooded a handful of rooms shortly after 9:30am. Classes at Bethel High School were dismissed around 10:45am. All after-school sports and activities still scheduled took place in the afternoon. Superintendent Dr Christine Carver says the rooms were professionally cleaned and classes are back on as normal today. Carver says the experiment will be investigated as a personnel matter to determine whether it was an appropriate experiment.
