    Hey!! Yep, I did it today. It was okay I guess, I had some time issues but I was able to finish it at least. I was expecting a much harder paper. As this one was easy I hope they don't make paper 1 and 3 harder... Did you do it today? How did it go?

    Thanks for your reply Yeah I did it today and found that it was OK too. But there were some hard bits though... :/ Also what did you put for the very last question (about where the heat is transferred or something), the one about separating to get a blue solution, the leaf questions and designing an experiment for concentration? Sorry that was quite a long list! Thanks!

    No problem For the last question i had no idea what to put, it's probably wrong but i put heat lost into the surroundings and lost as sound energy(probably wrong :/). For the separating one i did filtration. The leaf question the destarch one to put it into a cupboard for 48 hours. to absorb carbon dioxide i put sodium hydroxide and the control as water. the starch test to boil it to become permeable put it into ethanol will become green place it into cold water to soften in and test for starch, safety precautions i included tie up your hair and wera googles. experiment E(i think) was brown as no starch as no photosynthesis as no co2 whilst experiment F would photosynthesize as co2 and h20 present therefore blue balck as starch present. For the designing the experiment i did a titration, used sodium hydroxide and the universal indicator where the volume of naoh used was measured etc....

    are u also doing paper 11 and 31 on the 25th?
