PADI Open Water Diver Course
Training is important because? - correct answerIt enables diving to be rewarding and meaningful, there
are potential hazards to avoid, reduce and/or manage and diving has risks.
Certification shows? - correct answerCertification shows that you met the course requirements.
You will be trained to what depth? - correct answerA maximum of 18 metres/60 feet.
What conditions are you qualified to dive in? - correct answerConditions as good as, or better than,
those in which you trained.
The three parts of the course are? - correct answerKnowledge development, confined water dives and
open water dives.
Knowledge development covers the principles, concepts and terms needed for safety.
Confined water dives allow practise of scuba skills in a pool under direct instructor supervision through
one or more mini dives.
Open water dives allow practise, application and demonstration of what you have learnt.
Completing the course allows you to? - correct answerDive without instructor supervision, obtain air
fills, scuba equipment and other dive services, plan, conduct and log open water dives and continue
your diver training.
What is the PADI four E philosophy? - correct answerEquipment, education, experience and
environment.
Scuba requirements? - correct answerAge - you must be at least 10. 10-14 earn the PADI junior diver
certification. 10-11 must dive with a PADI professional and 12-14 must dive with a certified adult diver.
What is Performance-Based learning? - correct answerPerformance-based learning means you progress
and attain certification by demonstrating that you meet specific learning objectives.
, What is Student-Centered learning? - correct answerStudent-cantered learning means that the course,
materials and instructor address how you learn most effectively.
What are 11 reasons to dive? - correct answerAdventuring and exploring.
Enjoying and observing nature.
Spending time with friends/family.
Getting out on and under the water.
Taking photos and videos.
Investigating sunken ships.
Taking on personal challenges.
Becoming familiar with new technologies.
Making new friends.
Making a difference in environmental issues.
Enjoying a new world.
Are you under more pressure underwater, and if so, why? - correct answerYou are under more pressure
underwater as water also has weight, which combines with the weight of the atmosphere. Water is
much fender and heavier.
What is the pressure increase for each 10 metres/33 feet you descent? - correct answerThe pressure
increases by one bar/ata. Likewise, it decreases by one bar/ata for every 10 metres/33 feet you ascend.
What does pressure change effect? - correct answerPressure changes effect the volume and density of
air. As you go deeper, the pressure increases and so a gas volume decreases and gas density increases.
This effects all air spaces in direct contact with your body.
How do air volume and density change with pressure? - correct answerAir volume and density change
proportionately with pressure. As you go from the surface to 10 metres/33 feet, the pressure doubles to
2 bar/ata. The air density is x2. From 10 metres/33 feet to 20 metres/66 feet, the pressure is 3 bar/ata
(1 air plus 2 water). The air density is x3.
