Below is a list of the common mistakes that people make when completing the various parts of the coursework.  If you avoid these mistakes, you are more likely to score higher marks.

Obtaining Evidence  (Recording Your Results)

1) Not making the table clear enough. e.g. missing headings or units, not labelling test1, test2 etc.

Analysing Evidence and Drawing Conclusions

1) Not explaining the main conclusion from the experiment  (e.g.  ‘the higher the temperature of the water, the more sodium chloride dissolves).

2) Missing out axis labels or units from the graph.

3) Not drawing a line of best fit OR drawing a line that is just joining up the dots.

4) Drawing a messy, sketchy line of best fit, instead of a SINGLE thin line.

5) Not using any scientific knowledge to explain their conclusion.  You can use your notes, textbook, internet etc to help with this explanation.

Evaluating Evidence

1) Not talking about the actual measurements.  Do they seem accurate ?

2) Not saying WHICH measurements are anomalous (do not fit in).

3) Not making enough comment about how good the method/apparatus was and what EXACTLY was wrong with it.

4) Not making enough SPECIFIC suggestions to improve the experiment and explain HOW this will work.

5) Not discussing WHY you might have strange results. 

6) Not explaining whether you think you have enough evidence to make your conclusion.  (Explain what you did to make sure that you collected enough evidence).
