Billick September 4th‚ 2010 Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration of the cold water was higher

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted..
