Paper 6 Tips and Tricks
 Explain why the experiment was repeated.

To reject anomalies to calculate mean to increase reliability

 A control experiment is made to compare results clearly in
colour change experiments and to test for only one variable
or to make sure that change is due to one specific factor in
experiments like plants.

 Some controls can be: 1) boil enzyme substance {for enzyme
experiments} 2) Same volumeconcentrationamountmass 3) same time
4) same speciestype 5) same typesize of apparatus

 Sources of errors:

 If the question did not mention that the experiment was repeated

 If the question did not mention cleaning apparatus

 In Benedict experiment if the question did not specify temperature of
water bath

 Not using a wide range of temperatures is a source of error

 Using long time intervals is a source of error

 Shaking can cause spillage and affects volume Improvement use electrical
or magnetic stirrer
