| Summary |
You probably know that oxygen is important to our survival, and the survival of most life forms on the planet... but what else does it do? Well, take a deep breath and get to know the 8th element of the periodic table! This week, we turn up the heat with a little oxywelding, stay a night at an altitude hotel and introduce ourselves to liquid oxygen. 101You probably know oxygen is pretty important to your survival and the survival of most life forms on this planet, but how much else do you really know about it? Let Dr Rob break it down for you.OXYGEN IN THE AIR EXPERIMENTJoin Junior Scientist Elizabeth in this oxygen packed experiment where she calculates the amount of oxygen in the air using oxidation. OXYWELDINGAll around you are metal structures and objects that wouldn't exist without welding and welding wouldn't exist without oxygen! Peter Bowen a teacher at Thebarton Senior College shows us a type of welding called Oxy-acetylene which uses an extra supply of pure oxygen.ALTITUTDE HOTELAt Victoria University they have developed facilities that can help athletes get fitter in their sleep. Sports Physiologist Dr Rob Aughey shows us around Altitude Hotel, a collection of ordinary looking rooms, which are special in the air they contain.OXYGEN RESISTANT PAINTSOxygen has always been a great enemy of art, but soon the war may be over. Melina Glasson, a Student Research at the University of Melbourne, is working towards making a paint that is resistant to attack by oxygen. EXTRACTING OXYGEN FROM AIRHow do you produce oxygen on an industrial scale? Well, you need to extract it from air, which is a little trickier than it sounds. Chemical Engineer Chris Read from BOC shows us exactly how this happens |
