When scientists make observations they cannot say that something is big or small. Scientists use tools or instruments to measure objects to determine the actual size of an object. By measuring and collecting scientific data, scientists can express observations precisely and clearly communicate the results. A science class is divided into two experimental groups. Group A has the task of using a graduated cylinder to measure a specific amount of liquid provided by the teacher. Group B has the same task with the same amount of liquid, but will be using beakers to determine the amount of liquid. After the experiment is completed and data is calculated by both groups, the teacher determines that Group A’s observation of the liquid is more precise than the observations of Group B. What could explain the differences in the observations of the measurements of liquids (volume) being different between the two groups? A) Beakers are not used for measuring liquids.

B) Graduated cylinders are not used for measuring liquids.

C) Beakers are a more precise tool than graduated cylinders for measuring the volume of liquids.

D) Graduated cylinders are a more precise tool than beakers for measuring the volume of liquids.
