Question
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 garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates.
Note: Consider reviewing how Ruby developed her conclusion on page 8 of this lesson to select the best answer.

Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.
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.
Ruby measures the heights of several species A, B, C, and D plants, each species for one week at a time for four consecutive weeks.
The statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates is: Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The best answer is:
Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The best answer to this question is:
Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
To support a scientific explanation concerning plant growth rates, Ruby needs to gather evidence under controlled and consistent conditions. By measuring the heights of multiple plants of different species (A, B, C, and D) for a week under the same conditions, Ruby ensures that the only variable being tested is the plant species itself. Additionally, finding journal articles that describe the growth rates of each species adds further credibility to the evidence collected since it is based on scientific research and findings. This approach allows Ruby to gather enough evidence to make an informed conclusion about whether species A grows faster than the other garden species.
