Data Gathering Process Form
The purpose of this form is to help you to more clearly define what method you
will be following in order to answer your problem.
Problem:
I will have four containers, each containing hydrogen peroxide. However, I will
differ the type of soap added. My different soaps will be hand soap, dishwasher,
soap and hand sanitizer. In this experiment, soap is added to make bubbles and
make it bigger when the elephant toothpaste” appears. Because each soap is
made of different particles and meant for different things, he product in the
experiment will differ.
Hypothesis: Your hypothesis needs to answer the problem. It needs to include
reference to two variables, the one that you will keep changing (manipulated
variable), and the one that you will observe for any changes (responding). You
should also state your reasoning behind your hypothesis (why do you think this
will happen?).
I think that if we put in different kinds of soap, it would then affect the reaction
time, because of the chemicals inside the soap. Also, it depends on how much
kick-start, the potassium iodide you use, and maybe if you put in more, the
reaction time will be slower or faster.
Method (or Procedure): As clearly as possible, and in point form, outline what
steps you will take to collect your data. It may help you to construct your data
table (see below) first. When writing your procedure, write it as a set of
instructions meant for someone else to be able to replicate your experiment. You
may choose to number your steps. If you are replicating an experiment you
found on the internet (or somewhere else), you MUST state this, reveal the
location of your source (so I can look it up), and reword the method in your own
words. This will ensure that you fully understand each step.
