Please would you complete your raw data table - as I said in the lesson, you can keep it simple and just include your raw unprocessed data, or go big time and try to include the calculated values. Whichever you choose, it must be a great clear table - for help please see the required practical guidance folder, including the tables that I have annotated with mistakes. 

Please as part of this process, complete all your calculations and put them into your main raw data table or in a separate one if you prefer to keep things simple. 

You need to calculate the change in mass and the percentage change in mass for each piece of potato, then finally calculate a mean % change in mass for each solution. 

Hw submission is Monday - please post a pic of your completed table(s) showing all your calculations into the page called RP3 my results.  This is so that I can review it all before we talk about graphs on Thursday thank you
