If students are measuring a cup of milk using a standard measuring cup, what might cause the difference in measurements by indiv
patriot [66]

The causes that might lead to a difference in measurement by individual students are-

A. The curvature of liquid in the cup may cause some variations in measurement.

D. Some students might try to be too precise with their measurements, but others might not be so precise.

            Measuring refers to the process of calculating or weighing the perimeter, area, or volume of a substance. While measuring the amount of liquid in a cup, we can measure it by using a liter scale.

            Due to movement in the liquid, the curvature of the water might fluctuate. Thus, while measuring the liquid, the children might have different results.

              The carefulness of the students is also another factor that should be considered. While some students would be very careful with the liquid and measure it after it has settled down and stopped moving, some other children might just want to do it and get over the assignment quickly. Thus it can also lead to a difference in measurement.
