Today we will consider Conclusion and Evaluation (CEv), aspect 2.
This aspect deals with the students thoroughly investigating the experimental method. What didn’t work well and why? What happened to make the quality of the results not as good as what they should have been? The reasons should relate to the direction of the calculated value with respect to the data book value.
The theme for the next couple of days will be Conclusion and Evaluation (CEv).
Aspect one is split into three parts and is, in my opinion, the hardest of all of the aspect to achieve a ‘c’ in.
DCP, aspect 3:
Students seem to find this difficult to achieve a ‘c’. The aspect is looking for students to correctly present their final answer (to the correct number of significant figures) and to display an uncertainty / error value (to the correct number of significant figures).
Today we will consider DCP, aspect 2. This aspect deals with the processing of the raw data collected in aspect 1.
It should involve an ‘IB CHEMISTRY type’ calculation – it should not be simply calculating averages or calculating 1 / t (for a rate). The calculation should be demanding enough that an IB Chemist should be able to carry it out (but not another student following another IB subject).
Today, we will move away from Design and consider ‘Data Processing and Presentation’ (DCP) aspect 1.
DCP is all about collecting raw data, displaying it and processing it.
Today we will focus on Design, Aspect 3.
In order to achieve a ‘c in this aspect, the student must write a detailed method. The emphasis is on the word detailed. The student should essentially be able to give another IB Chemist the method and they would be able to carry it out.
Sorry for the delay – I have been on my half term holiday 
So, my last posting covered Design, Aspect 1 – today, it is onto Design, Aspect 2.
Today we will look at Design aspect 1.
This criteria is really split into two parts – the research question and the variables.
Over the next few days / weeks, we will focus on the various skill areas and aspects for the three internal assessment (IA) criteria, namely:
