EE feelings

I have started working on my EE already with my supervisor, who is also my chemistry HL teacher. When we first had an Extended Essay meeting, she has suggested some of the ways that I could alter in order to make the experiment more accurate and interesting. For example, I could use different teas and measure the oxidating power of them by measuring the time it inhibits the Briggs Rauscher reaction, and also correlating it to the number of antioxidants by using an antioxidant pill to conduct the reaction. Also, I have listed the things I need before my preliminary trials start so that my trials will go as smoothly as possible.

I have started my preliminary trials before the April break but unfortunately was unable to finish it. My first trail was not a success, because in the end there is a purple gas formed instead of very clear oscillations. This might be because that the temperature is too high ( above room temperature) and iodine I2 turned into a gas. This time, I have tried to create bigger stocks but smaller reactions, so it would cool more effectively and hopefully oscillate normally.

Next, I need to plan out that what tea I am supposed to use. The tea helps to fight free radicals in the bodies as it has antioxidating properties, and helps to protect the DNA from being damaged.  My experience helps to suggest that the amount of tea that one should drink in one day in order to uphold personal health.
