Sponge Experiment Essay

Methods
The steps and procedures of an experiment are one of the most important part of an experiment besides the materials. The steps to this experiment are very simple.
Step 1: rub Coke on a rusty piece of metal with a sponge damp with Coke for three trials. Each trial should have its own section on the rusty metal.
Step 2: with a new sponge rub Diet Coke on a different section of the metal for three trials while the sponge is damp with Diet Coke
Step 3: with the last sponge rub Pepsi on a different section of the metal for three trials while the sponge is damp with Pepsi
Step 4: record how long it took for the rust to be removed from the metal for each of the sodas and their trials.

Materials The materials in an experiment are very important.

The soda will get everywhere when you pour it on to the sponge. The safety hazards are very important in this experiment there is really no safety hazards unless you slip on the soda. Or the rust is somehow gets in your body. So after you use the sponges to remove the rust do not use them to clean anything. Unless you clean the sponges thoroughly so you can get the rust particles out of the sponges. This experiment should not take more than twenty to thirty minutes depending on how many breaks in between each

The hypothesis was incorrect the Diet Coke removed the rust faster, but the Coca Cola removed the rust a lot better but not in a short time. As in appendix I, the Diet Coke and the normal Coke’s averages were a second away. As seen in appendix I, the Coca Cola removed the rust the fastest. The Pepsi removed the rust the slowest and was not as clear as the Diet Coke or the normal Coke. Though in trial two the Diet Coke removed the rust faster than the normal Coke, see appendix I. In trial three the normal Coke removed the rust faster than the other sodas but the average states that the Diet Coke removed the rust one second faster than the normal Coke. The Pepsi’s average was very low compared to the others and did not remove the rust as clear. In this experiment there were many possible sources of error in this experiment. It could be that the bumper was tilted so the sodas could have mixed when I was rubbing the sodas on the bumper. There was also nowhere for the soda to go so it was just sitting there so that could have messed with the time. From the experiment the sodas did remove some of the rust so just image what the soda does to the intestines, especially the
