GCSE ISAs

You only need to do ONE good ISA in each science during the course, although here at Skinners' we do two, so your 'best one counts'. If you miss one through illness, it can not be repeated - you will need to wait until the next one.

The ISA you submit will be worth 25% of your final GCSE mark so it's worth getting as good a mark as possible. To do this, here are some useful tips:

So what’s left to do??  

1. A planning lesson where your teacher sets the context of the practical

2. A practical lesson where you generate your own results and draw a table and graph

3. A written evaluation lesson where you write about your own investigation (part a), and analyse results from a hypothetical situation / student (part b).            

  EVALUATION.          There were definitely errors in your technique, no matter how well you thought it went.

The apparatus and materials you used, the accuracy of the results (how ‘close’ the repeats were to each other – so called ‘anomalous’ results feature here), and the validity of the results ( how much they ‘matched’ the prediction.)

So for all those errors you identify, you should be able to suggest improvements to this investigation (note the plurals!). This makes your result 'more reliable'.
