Limitations => Effects of the limitation on the => improvement experiment
1.Temperature is not kept constant while mixing the enzyme withthe solution of milk and calcium chloride
Lower or higher temperature can change the rate of the reaction(speed up or slow down) so the time taken for the milk to coagulate is going to vary
keep the test tubes in a water bath throughout the expirement
2.Judging of the thickness of the milk is done by eye
Lack of consistency in judgment may lead to less precise, less reliable and less accurate results
drop an object inside the test tube and measure how far it sinks
3.Measurment was only taken every 5 seconds
Limits the level of precision
take measurement every 2 seconds
3. Better stirring to more thoroughly mix the enzyme with the milk calcium chloride solution
the time it takes for milk coagulation is inconsistent
use an electrical stirrer
4.Lack of range of independent value(concentration of calcium chloride)
Makes it difficult to identify the presence of a trend
add a concentration of 42,6,8,10
5.There isn't a sufficient number of replicates
unable to detect anomalous results thus decreasing reliability
perform at least three replicates
