Claim: I think that when you are measuring volume with either a ruler or with water, it should be  exactly the same thing because 1 cm^3 is the same as 1 ml. 

Evidence: 

Our graph shows that the slope stays at about the same rate the whole time. I think the reason that there were errors, was because when we were measuring with water there were sometimes air bubbles that could not be filled with water. Also there may have been human error with reading the ruler or graduated cylinder we used. The equation was W=(0.9212mL/cm^3)r+0mL. The slope was 0.9212mL/cm^3.  The y int was 5.630 mL.

Reasoning:  The slope stays very consistent which helps me know that 1 cm^3 = 1 mL. Matter behaves in the same way, weather it is measured as a solid or a liquid. The outcome of the measurements should be the same.
