Question

In an experiment for science class, ten onion plants grown in individual containers are separated into two groups. One group is placed in a room that gets sunlight and water daily, and the other group is placed in a dark room and given water weekly. After three weeks, the plants are observed.

Which best describes an error the students made in the experiment?

Answer 1

B. Changed more than one variable

Answer 2

Onions go for full sunlight, enough soil moisture, and fertile, well-drained garden soil. They will survive if planted in partial shade, but the onions will be smaller and the plant will be more susceptible to pests and disease. However, Onions are unable to grow in full shade. So, the other group that was placed in the dark room but given water weekly by the student did not grow.
