Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species ( species A) grows faster than the other guarded species ( species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates.

Question

Note: consider reviewing how Ruby developed her conclusion on page 8 of this lesson to select the best answer. (1 point)
A Ruby measures the height of several species A, B, C, and D plants for a week under the same conditions to find journal articles that describe the growth rates of each species
B Ruby measures the heights of several species A, B, C and D plants for a week under different conditions and finds a turtle article that describes the growth rate of species A
C Ruby measures the height of several species A, B, C, and D plants, each species for one week at a time four consecutive weeks
D Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A

Answer 1

The best answer that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates is:

C Ruby measures the height of several species A, B, C, and D plants, each species for one week at a time for four consecutive weeks.

This option indicates that she is systematically measuring the growth of all relevant species over an extended period, which allows her to gather sufficient data to compare their growth rates scientifically.
