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, each species for one week at a time for four consecutive weeks.

To effectively gather enough evidence to support a scientific explanation concerning plant growth rates, Ruby should ideally measure the heights of multiple specimens of each species under the same consistent conditions over a sufficient timeframe. This helps to ensure that the data collected is reliable and can be compared fairly across species.

Among the provided options, the best 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 approach allows for comparative analysis of growth rates across all species over a set period, which is essential for drawing valid scientific conclusions.
