Alternatively, you could look at the saponification values of different fats. It should be clear from these guidelines that you need to choose your own project and completely own it. You could compare the experimental value with the stated value, and look at different brands of iron tablet. James awarded it a mark of 7/24 which I felt fairly reflected its worth according to the IB assessment criteria. This work can be on primary or secondary data but well analyzed and critically evaluated. 28. document.write(new Date().getFullYear()) InThinking Any IA lab should be thoroughly risk assessed by yourself and your teacher should check this risk assessment.
