In my science 9 class we did an experiment involving different sorts of drinks and then seeing how much vitamin C each of them contain. What we did was grab 6 test tubes and then put 5ml of a starch solution into each of them. In one of the test tubes we put ten drops of vitamin C. And in the others we put ten drops of different types of drinks. We had blueberry juice and straw berry and banana juice, also 7-up and iced tea and finally gatorade. Then we waited and watched for the results. My reflection on this experiment was that you had to pay alot of attention to the amounts of liquids that you put inside of the test tubes. Because you needed to have the exact measurments. It was very cool to see the colours changing.
