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 different conditions and finds a journal article that describes the growth rate of species A.

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 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.
It seems there are duplicate responses in the list provided, but the answer that best 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.
This is because scientific investigations require controlled experiments where variables are kept the same across the subjects being studied (in this case, plant species A, B, C, and D). Observing these plants under the same conditions allows for a fair comparison of their growth rates. Additionally, consulting peer-reviewed journal articles enhances the credibility of Ruby's findings, as journal articles generally provide reliable information that has been vetted by experts in the field. This combination of controlled experimental data and scientific literature would give Ruby substantial evidence to draw a conclusion about the relative growth rates of the plant species in her garden.
