AQA Biology ISA 2015 Diffusion GCSE

Is it okay if somebody marks a method that i did for me?If it is too much, pls can you give it a quick skim and let me know what i can do to improve it. This will be greatly appreciated, thank you!
The experiment is to find out how concentration affects diffusion.
Equipment
Labatory Balance,spatula,250ml beaker, potassium permanganate crystals,stop clock.
Method
1)Fill the beaker with 200ml of tap water.2)Connect the labatory balance to the mains supply and weigh out 2 grams of potassium permanganate crystals on the balance.3)After you have weighed the potassium permanganate crystals on the balance, transfer 2g of the crystals to the beaker containing the water using a spatula.4)Do not stir the solution.5)As soon as you have added the crystals, start the stopwatch and time how long it takes for the crystals to completely diffuse. You will know the crystals have completely diffused when the whole solution turns purple.Only stop timing when you can no longer see any clear areas.6) Repeat this experiment with the same mass (2g) of potassium permanganate crystals 3 times, in order to get reliable results and check for reproducibility. This will also help you to discount any anomolies if necessary.
Record these times in a results table and repeat the same experiment using 4g of potassium permanganate crystals and then 6g of the crystals. For each mass, repeat the experiment 3 times.

Hello
It's been a while since I did my isa but Ill try my best,
include resolution somewhere, so say fill the 250ml3 beaker (with a resolution on 50ml3) with 200ml3
Maybe say check the scales are zeroed because otherwise it could cause errors
have you stated the variables?

sorry this isn't great but I'm sure I wrote out what i needed to include for preperation for my own isa I'll have to root it out tommorow for you

sorry it's pretty shoddy help haha

Ugh we're doing sooo many ISA's at the moment :'(
Include tap water in your equipment c:
I would write steps 3-6 like this:
3) Using a spatula, add the 2g Potassium Permanganate to the beaker of water and start the stopwatch at once.
4) Do not stir, and wait for the solution to turn purple. Immediately stop the stopwatch and record the time on the results table. (This bit is super important as there is a bullet point asking when you will record your results, so specify it ^-^) Everything else you have written for step 5 can be included in how you will make the experiment a fair/valid test, or you could talk about how different people will have varying judgement for some possible anomalies
And then your steps about repeating afterwards
Hope this helps *-* Sorry if the tone sounds patronising or anything, I don't mean it to xD

Have you done the ISA? or...naa

If anyone wants any help I would be happy to try and help you Im doing my GCSE's this year but I have already done and received all my ISA grades ( I do AQA too).. I got 47/50 in my bio isa which is a high A* and 49/50 in my chem isa so happy to help

We haven't found out yet :'(
Although I think I must have, because i'm predicted A*, and the teachers 'suggested' we redo it if we got below our target, and I wasn't asked to But tbh there's not really much you have to learn/do for it, so it's an easy 25% of the GCSE

Alright thanks, well pls can you give me some specific advice on how to get the highest possible marks. thanks

Well the best way to start is to look at the controlled assessment examiner report for June 2013 on the AQA website. I know this may seem pointless and that's what I always thought of examiner reports but I was wrong!! Especially for the CA it tells you what questions will definitely come up in paper 1 (as they are mandatory) and other ones that usually come up and the way in which you should answer them. Most of the questions in paper 1 are generic meaning that you can therefore write your answers to any possible questions from looking at past papers and the examiner reports before even stepping foot into the exam!! Learn and understand your answer and you can do paper 1 and probably come out with 100%!!! Hope this helps a bit
