### sense in the lessons

In home safety lessons, children learn where the stopcock is: if a pipe bursts or a tap will not turn off, an adult turns the stopcock to stop the water and prevent a flood. In the UK and Ireland it is often under the kitchen sink. In science it shows how a valve controls the flow of a liquid. Phrases: «turn off the stopcock», «the main stopcock». In the USA people more often say «shut-off valve».
