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, each species for one week at a time for four consecutive weeks.
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.
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 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 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 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, each species for one week at a time for four consecutive weeks.
The correct answer is:
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.
This statement describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates. By measuring the heights of several plants from each species over a period of four weeks, Ruby can observe the growth patterns and compare the rates between species A and the other species B, C, and D. This allows for a more comprehensive analysis of the growth rates and helps to establish a scientific explanation.
The statement 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, each species for one week at a time for four consecutive weeks.
This statement shows that Ruby is collecting data on the heights of multiple plant species, including species A, over a continuous period of four weeks. This allows her to compare the growth rates of different species and draw conclusions about which species grows faster.
