Question

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. Which is most likely to result in the greatest amount of error in their scientific experiment?

Answer 1

One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table.

Step-by-step explanation:

Just did the test

Answer 2

In doing research or experiments, it is necessary that the variables applied on the test subjects are the same. In the problem, the factor that will most likely result in the greatest amount of error will be the plant subjects. Different plants have different growth rates, and their growth can be affected by the many variables such as sunlight, disturbance, location, etc.
