In the Physical Education and Science courses in our school "Do I need to know this?" Program is carried out. The program consists of activities prepared in response to the question “Do I need to know these subjects?” The pressure and diving activities carried out with our 8th grade classes show how important the information we have about pressure is for our lives. At the event, when explaining the rules about diving, the accent, sea drunkenness and  other such events are shown in the demonstration method. At the end of the activity, our students had the opportunity to discover what pressure meant for our lives.
