When accidents occur, the administration usually responds by imposing a moratorium on demonstrations and lab activities. Imagine if authorities reacted in a similar manner in the real world. Airplanes would no longer fly and cars would no longer be driven. Just as we depend on planes and cars for transportation, science teachers depend on labs and demonstrations to teach effectively. So, the proper response to an accident isn’t to ban labs and demonstrations, but to identify the cause of the accident and introduce or enforce safety guidelines for prevention.
