Which of the following best describes a person doing science? A. Dominick uses a computer to do his math homework. B. Lindsay measures the sizes of the craters on the Moon. C. Isabel invents a new kind of doorknob. D. Murray randomly predicts the result of a coin toss.

B. Lindsay measures the sizes of the craters on the Moon.

Explanation:

Science is about making a hypothesis, doing experiments, making observations, recording data, analyzing data, interpretation of the data, and writing meaningful conclusion. Here Lindsay measures the sizes of the craters on the Moon, which falls under making observations and recording data so Lindsay is ding experiments.

Dominick is simply using technology, Murray is simply guessing a number and Isabel's invention falls under engineering.

B. Lindsay measures the sizes of the craters on the moon.
