Data

At the start of the experiment, we will record the appearances of the plants as they have not yet been affected by the pH of the liquids that they are placed in. This is to ensure that any differences in the appearance of the plants are caused by the changes in pH of their growth medium and not because of prior damage (holes in eaten leaves, etc).
At the end of the experiment, we will again record the appearances of the plants in a table to chart the changes observed in the growth of the plants. The parts of the plants that will be observed are the leaves, stem, roots and the plant as a whole.
The height of the plants will not be measured as this is a short term experiment and there will not be enough significant growth in the plants to be able to determine if the plants' growth is affected by the changes in pH or not.
