Yes, it is possible and there have been experiments done with animals.  Not aware of any human trials.  I believe that there are some long-term effects that need to be worked out before it would be declared a safe activity.\n\nIt's not liquid O2, but rather a liquid in which oxygen can be dissolved in  (like water), but is compatible with the avioli in the lungs and the lungs can extract the oxygen and return CO2 to the liquid.  \n\nNormal water (fresh or saltwater) damages cells in the lungs, so there's a little more to it.

Liquid Breathing\n\nA lot of you I am sure have seen the movie "The Abyss". If not then it doesn't matter but what is important however, is one of the diving techniques that they use. This technique is called Liquid Breathing. Until not long ago, people thought that this was fictitious and was not possible but in fact it has been around for a lot longer than you might think!\n\nThe general type of liquid used by the US Navy and other Navies in the world generally have a perfluorocarbon type composition. The type of halide attached onto the molecule depends but it is either fluorine or bromine. However, the only problem associated with using bromine is that it is a very strong greenhouse gas but it could be regenerated through special filters and rebreathers.\n\nADVANTAGES\n\nIt  seems like an odd concept but:\n\n1- Due to its density, Liquivent (marketed name for liquid breathing liquid) can carry as much as 25 times as much oxygen than blood and it has enormous potential for patients with lung and breathing disorders. \n\n2- If fluid is taken into the lungs whilst diving, then the pressure in the body could match that of the pressure of the surrounding water. Thus breathing would be easier and lower concentrations would only be needed. \n\n3- Thus, this would also eliminate the need for decompression and its inherent problems i.e. nitrogen narcosis and the bends.\n\n4- A given volume of oxygen-saturated fluorocarbon contains 3 times as much oxygen as the same volume of air or whole blood.\n\n5- According to the movie "The Abyss", the deepest suit dive was to 4800ft which is equivalent to about 300atmospheres of pressure! Tests with mice have been done at pressures of up to 8000ft.\n\nHISTORY\n\nThis concept originated in the mid 60's when Dr Kylstra a physiologist realised that salt solutions could be saturated with oxygen at high pressures. However, after several experiments he concluded that this mixture becomes toxic due to the build up of carbon dioxide. Therefore, a new mixture that could be saturated with oxygen and get rid of carbon dioxide quickly and efficiently had to be thought of.\n\nAfter further experimentation in 1969, Dr Clark realised that oxygen and carbon dioxide were very soluble in fluorocarbon liquids like freon. Assuming the lungs could cope with this material, Dr Clark figured that these fluorocarbons could support respiration of animals.\n\nLater developments\n\nDuring later years, the techniques of liquid breathing were constantly refined and improved. The survival rate of all the tested animals in recent years has been very high, thanks mainly to improvements in carbon dioxide elimination. Current liquids used can dissolve over 65 ml of oxygen and 228 ml of carbon dioxide per 100 ml perfluorocarbon. By the early 1990s this procedure was developed:-\n\n   1. The animal was anesthetized with intravenous sodium thiopental.\n   2. The animal was put on its back. A tube was placed down its airway, ready for the liquid breathing medium.\n   3. A blood sample was taken. The temperature of the liquid was adjusted correspondingly. It was no longer necessary to make the animals hypothermic.\n   4. The perfluorocarbon was instilled into the animal's lungs through the tube.\n   5. A floor-mounted 3-litre reservoir was filled with the perfluorocarbon. The liquid was driven by a pump through a series of machines which warmed and oxygenated the liquid and took the carbon dioxide out of it. The liquid flowed through a tube into a 3-way pneumatic valve which directed flow to the animal. A computer controlled the inspiration (18 ml of fluid per second), pumping the liquid into the animal's lungs, then back out again to the reservoir, at a rate of about 6 complete respirations per minute.\n   6. At the end of the test, the animal was tilted for about 15 seconds and the perfluorocarbon was allowed to drain from the lungs. This can be seen in the film The Abyss where Ensign Monk drain

The scientific supply companies like VWR probably have them.\n\nI searched for "oxygen reduction potential electrode" and got a bunch of hits.  Try that.\n\nYou'll also need a meter to attach it to.  Many better pH meters can handle this kind of probe as well.

yes! liquid oxygen and liquid hydrogen.  mix them together, light a match and stand back.

It is possible to investigate photosynthesis by carrying out an experiment that demonstrates the production of oxygen. If oxygen is being produced, photosynthesis is taking place. In this experiment, you will use a tube\nthat contains baking soda solution  in order to increase  the rate of photosynthesis.\n\nBaking soda solution supplies carbon dioxide necessary for photosynthesis. When the experimental tube is subjected to light, the leaf disks will produce oxygen gas and float to the surface of the chamber.\n\nNote:\n\nPhotosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask. It is done by using the principles of the kinetic theory of matter.\nAnother cool project might be doing something with dry ice. Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions. Make some dye molecules or something.\n\nHope one of these ideas works for you.

well theres alot of material i can provide you with but i dont know what particular experiment you are designing as there are always different experiments within an experiment.\nanyhow, i think this is an example of an experiment for photosynthesis and respiration and their pH levels.\n\nhttp://www.science.siu.edu/plant-biology/plb337/old_st_papers/emmert.pdf \n\n\nif you are doing the same experiment, i guess you will find this one really helpful.\n\n.. Good Luck

I know of at least 4 ways.  I think that the distillation or membrane separation are the most practical.\n\n(1)Distillation\nOxygen and nitrogen have different boiling points.\noxygen: 90 K\nnitrogen: 77 K\nIf you cool the mixture to a temperature between the boiling points of each you will be in a two-phase region.  There will be a gas phase rich in nitrogen (because it has a lower boiling point) and a liquid phase rich in oxygen.  A distillation column can be used to separate the phases and collect them in a continuous, pretty efficient process.  I think you have to do something special about the argon in air when you do this (like have more than one separation step, more than one distillation column).\n\n(2)Adsorption\nOxygen and nitrogen gases may adsorb to (stick to) the surfaces of certain compounds (like metal surfaces).  If you make a series of tubes lined with a substance that preferentially adsorbs (for example) oxygen, you will get a gas output that has less oxygen in it.  In a well-designed case, the adsorption is reversible.  Increasing the temperature of the substance will causes the oxygen to leave the solid surface and once again become a gas, giving you a relatively pure oxygen stream.  If the purity is not good enough, you can collect the streams and repeat the process (use a longer tube).  I don't know of an example of an adsorption material off-hand.\n\n(3)Stripping\nStripping is the process of passing a gas through a liquid and may involve chemically removing one of the components of the gas.  If you bubbled air through a liquid that had a chemical in it that reacted with oxygen to form a compound then the gas that reaches the top will be nitrogen-rich.  For example, your blood contains hemoglobin, so that when it is in contact with the air in your lungs the oxygen sticks to the hemoglobin, forming a chemical complex.  This is a lot more effective than limiting yourself to an oxygen supply based on whatever gases can dissolve in your blood. \n\n(4)Membrane Separation\nOxygen and nitrogen have different permeability in membranes.  They can diffuse through solids, but at different rates.  I think oxygen typically has high permeability.  If you pressurize the gas mixture and pass the gases through a bundle of tubes (high surface area is key) then some gas will pass through the tubes axially and some will diffuse through the walls radially.  The stream that passed through the tubes will be richer in nitrogen, since it is less permeable.  The stream that diffused through the walls of the tube will be richer in oxygen, becuase it is more permeable.  Repeat the process to get the desired purity.\n\nAn artificial lung can be made by passing blood through a long set of tubes that have oxygen on the outside of the tubes.  The oxygen diffuses into the blood through the permeable tubes.

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?

The answer is yes to your question of mixing pure O2.  You cannot, however, breath pure O2 at depth.  This can be lethal.  But mixing is known as Enriched Air Nitrox or EAN.  By adding O2 to the air, you are decreasing the amount of Nitrogen and in turn, decreases your exposure to decompression sickness (the bends).  Proper training in the area, makes it a very safe practice.

An idea would be, "Which gas could you fill a volleyball up with that would make it go better?" They you can have regular air, carbon dioxide, and helium. Then you make a hypothesis based on what you know, try one of them, and see if you were wrong.

You could do a report on how Ozone O3 is created and how much energy it needs.  Also how it is broke down.
