Ruby has observed that plants in her garden very 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 Rudy gathering enough evidence to support a scientific explanation concerning plant growth rates.

Answer 1

Ruby can gather enough evidence to support a scientific explanation concerning plant growth rates by conducting a controlled experiment in which she measures and compares the growth rates of plants from species A (the plant she wants to investigate) and species B, C, and D. She should ensure that all other variables, such as sunlight, water, and soil quality, remain constant for all the plants. By collecting accurate and precise measurements over a specific period, Ruby can determine if species A grows faster than the other species. This experimental approach provides solid evidence to support a scientific explanation of plant growth rates.
