Publisher's Synopsis
The aim of the experimental design is to answer specific questions, in order to determine which questions a particular experiment can answer, we need to know what was tested and what was measured during the experiment. We hold all other variables constant and change only what we want to test and measure. I will leave all the experiences without an answer because I haven't tried them. It is just ideas and training for you dear reader on scientific thinking and the results should not be specific and known in advance, but it is scientific honesty to be as it happened and not as we want.
