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.
(1 point)
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, 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 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.
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 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.
This answer aligns with the scientific method as it involves making measurements of multiple plant species under controlled conditions and gathering information from credible sources (journal articles) to compare and analyze the growth rates of each species. By conducting a controlled experiment and referring to scientific literature, Ruby can gather enough evidence to support a scientific explanation concerning plant growth rates.
