  2. Introduction The members of Blue Group Lily, James, Malik, and Makena present to you a power point about a Chapter 1 Overview of Scuba Diving. Well what’s in Chapter 1 again? Well in Chapter 1 for example is Buoyancy, Air Pressure, Equalizing, and more!

  3. Buoyancy If an objects floats, we call it positively buoyant; if it sinks, we call it negatively buoyant ; and if it neither floats nor sinks , we call it neutrally buoyant. Positive Neutral Negative

  4. Air PressureSame air, Smaller space If you take an air volume underwater with you in a flexible container or an an inverted jar, the volume changes proportionately with pressure.

  5. Sinus Areas Do not Dive with congestion or sickness!

  6. Equalize - +

  7. The Ease to Breathe • Using a snorkel saves air in your tank when your on the surface.

  8. Knowing your BCD Inflation Hose Low Pressure Inflation

  9. No O-ring, No Diving • With no O-ring on a Scuba tank your regulator will not seal.

  10. Pointing out the Regulator First Stage Alternate Air Source 2nd Stage Pressure Gauge

  11. Scuba Pressure Gauge • A pressure gauge (or can be known as SPG or “contents gauge”) tells you how much air you have during a dive. • When your pressure gauge is in the red zone be sure to inform your instructor that you are low on air.
