3. I agree on 1 and 2, on 3 none are good methods. I would have used a bar chart. I suppose a line chart is a near relative, but I wouldn't use it.

4. The independent variable is D (The material the cups are made of). An independent variable is what is changed! The amount of water in each cup is the same...50mL, so that is the control group.
