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.
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.
B. Ruby measures the height of a species a plants for a week and finds an anonymous gardening blog that describes the growth rate of species A.
C. 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.
D. Ruby measures the heights of several species A, B, C, and D plants, each species for one week at a times for four consecutive weeks.
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.
The statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates is:
C. 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 statement indicates that Ruby is conducting an experiment where she measures the heights of plants from different species (A, B, C, and D) for a week under the same conditions. This approach allows for a controlled experiment, as all plants are subjected to the same factors that could affect their growth. Additionally, Ruby consults journal articles, which are peer-reviewed and reputable sources of scientific information, to gather information about the growth rates of each species. By combining empirical data and existing scientific knowledge, Ruby can analyze and compare the growth rates of different plant species, providing sufficient evidence to support a scientific explanation.
