sense in the lessons

In science and safety lessons about electricity, power stations make electricity, pylons carry it, and substations change the voltage before it reaches homes. Safety: never climb into a substation or fetch a ball from one — the electricity can kill; tell an adult or call the power company. Signs say «Danger of death».
