experiment today, testing the rate of reaction of rennin in milk. me and paul's experiment didn't really go anywhere, then we found it it wasnt meant to.
we added 1mL of rennin (enzyme) to 10mL of milk at diff temperatures. 10, 37 and 50. our control was just milk sitting on its own.
only the 37 was meant to clot though, coz 10 is too cold, the enzymes would be inactive, and the 50 would denature the enzymes.
we altered temperature of milk in test tubes by keepnig them in beakers of water of varying temperatures, measuring the MILK's temperature with a thermometer. each reaction was timed using a stopwatch, but not recorded coz it went nowhere -.-
