When Miss Cloete announced to the Grade 9s, “Today we are going to learn about Hydraulics and Pneumatics.”, she was met with silence and blank stares… “Have any of you ever seen a jackhammer breaking up concrete or tar? Have any of you ever been in a car when the breaks are used? Does your blood circulate around your body? All those systems make use of hydraulics or pneumatics!.

Interest was peaked. It is such a pleasure to teach technology that is seen in “real-life” situations. The students tried to figure out the systems for themselves using balloons, syringes and water. A few squeals were heard when their systems failed and water squirted out all over the whole group!
