In Paper 1 of ISAs the questions, excluding one that you have to apply your knowledge for, are nearly always exactly the same.
The first question asks about your hypothesis.
For the first mark simple state your hypothesis which you have researched and planned.
For the other two marks where you are to explain try and find some contextual knowledge.
An example of a 3/3 answer would be:
Hypothesis - If I change the concentration of the solution, the mass of potato will change.
Explanation - I found an example on the internet that described how in dilute solutions water passes into cells and in concentrated solutions water passes out of cells.
The second question is on comparing your two sources.
Write them out (numbering them 1 & 2) then make a statement about each
E.g. Source 1 was useful because it had lots of information about the topic and proposed an experimental idea which I could incorporate into my own.
Finish the explanation with a comparative.
E.g. Source 1 was more useful than source 2 because the information was more detailed and relevant.
The third question is the method question.
Write sub-titles for each section: Method, Equipment, I&D Variables, Control Variables/Fair Test, Risk Assessment
Method - number your method with numbers and explain it clearly so that someone who had no idea what your experiment was about could still understand and do it.
Equipment - list your equipment including measurements (e.g. 100ml measuring cylinder)
I&D Variables - simply state the two variables.
Control Variables - state what you are keeping the same and say how you are going to do it (e.g. temperature - using a thermometer and water bath at 30 degrees celsius)
Risk Assessment - state a risk and what you will do to minimise it (e.g. sharp objects - handle with care)
As for the 4th question, there are various possibilities just make sure you write as much as you can to try and scavenge marks.
The 5th question is just drawing a table - make sure you write the dependant and independent variables as the table titles and include units!
Hope this helped!
