Hi,
I know how you can not tell me anything about how to answer our question, but I need advice on how to write the coursework itself. I think I already know the information, but I need to find a way to set it out. We are being told at school by the teacher, but he wont have done his in ages, and the board will have changed, I am under AQA Exam Board and very scared. I wanted to see if anyone could help me with preparing, and that. It is better from a student who has done it, rather than a teacher who did it 20 years ago. No offense if any teachers read my post, but you get the jist.
Thank you so much!

Preparation exam
Performing experiment
Case study exam
the preparation exam involves writing your hypothesis, writing a prediction, method (worth 9 marks, 1 for English! ) and drawing up a results table.
then you perform the experiment and write up results
Then in the second exam it is split into 2 sections in Section A you answer questions based on your results (like reliability, errors and averages ) in Section B you answer questions on case studies (experiments that are related to your experiment or context) these questions can involve calculations, using your chemistry knowledge to explain what happens and mostly reading off graphs, the last question is normally comparing all the case studies together
hope this helps

Thank you so much! Only thing I am now stuck on is the graph! We are doing the graph on how long the it fizzes (Hydrochloric Acid + Ore) and am not sure how I would set this out in a time graph, I know how you would do the time part, however, what would be your other scale, time and...? So confused!

Yes chemistry ISA - Carbonate Ores
Independent Variable - Calcium Carbonate
Dependent Variable - Measurement (time)
Control Variable - Acid and method
How would I put the experiment to find how much calcium carbonate which is inside an ore.
I know the experiment, it's just the graph which is puzzling me:/

Excusing my awful artistic skills on a computer. This is part of what sort of graph I would draw. I know I need a line though, line graphs are what gets you the marks, as they are more accurate than the others. I have seconds, but what would I place on the other axis to make the line go up, or down and that, I am confused!
Say if I did my experiment and it took 48 seconds to stop reacting (fizzing), I would go up to nearly 50. However, where would I go for another scale, very confused

the other scale would most likely be amount of CaCO3 added in grams and that would go along the bottom

Sorry some of the writing is oddly sized, and going the wrong way around the axis. However, I have this graph now, but how would I plot an example of results, such as...
Ore - 5g
Acid - 25g
Time - 20 seconds
Ore - 10g
Acid - 25g
Time - 32 seconds
Ore - 15g
Acid - 25g
Time - 48 seconds
Ore - 5g
Acid - 25g
Time - 20 seconds
Ore - 10g
Acid - 25g
Time - 32 seconds
Ore - 15g
Acid - 25g
Time - 48 seconds
the acid is a control vairaible to ensure it is a fair test

Ah, thank you! So is that my basic Chemistry graph! Got section 1 exam about my method, pretty sure that is alright. Is there anything else you think I should include in any of my information, or remember to include? Thanks

Ah, averages? How would you calculate that? (sorry to be annoying, just want to be able to do everything) Units on axis?
Thanks for the luck!

and average you take repeated readings , add them up and then divide by how many repeats there were
