Who is the scientist?
The “I” means whoever is running the experiment. This is the students
Which one of these independent variables is the control? The Blue ink on white paper, since this is the conditions that we first observed i.e. the “normal” conditions Which part of the independent variable is the constant? The blue ink stays the same in both experiments, only the background changes to test the contrast. Would it be fair to use yellow ink on white paper to test the contrast (a light color ink on a white paper)? No. because that experiment also tests the color of ink (since the color changes), not the contrast.
