I teach for the MArines and have to teach PPo and law of absorbtion to a bunch of young marines. I know the laws but am having a hard time conveying it. ANy thought would be great and visual demonstrations.

Tell them a bunch of marines, and soldiers are pushing on a truck. You get partial push (pressure) from the soldiers, and the rest from the marines.
ha ha I would love to but I might loose my teaching quals
Alright, then football players, and wrestlers.
i need to explain it in depth such as gas toxcity increase into the body and surface area and volume and such
they get that the mixture of a gas is eual to the sum of its parts. But I need to relate that to the change in ppo at depth and how it relates to gas toxcicity

tru but then I have them thinking about libo and not about diving. thank you though. I have come up with the idea of using a seal a meal in class to show them how a bag(lungs) filled with marshmellows(gas) is full on the surface but at depth becomes compressed and therfore alowing more room for more marshmellows. and how at surface the preasure the marshmellow exerts on the bags(lungs) is not that great but how at depth they are pushing harder on the bag therfore becoming absorbed into the tissues more rapidly. this way I cover boyles.henerys,and daltons law all at once.
I am having a hard time showing how 32% nitrox is .76ppo2 at 45' but 1.58ppo2 at 130'. so 32%on surface is like 132% at 100'(just an estimate not actualy doing the math) I can do the equation and show them but its hard to explain and visualize why it is
hmmm when were you in? We have some very inteligent people in our Corps but I am a firm believer that the class need to be tought to the lowest common dinominator
