Introduction/ Plan The title of my investigation is FIZZY CHIPS. I will be investigating how changing variables in an experiment effects the rate of reaction. I will do this by observing a reaction between marble chips and hydrochloric acid. There are many variables, which will affect this experiment. The variable I will be changing is the amount of chips. To make this a fair test I must keep the other variables the same right thought the experiment. Preliminary Results Before I decided on a method I carried out some preliminary experiments.
