In science class, maria observes that a white-colored flower has shades of red when it’s watered with red-colored water. she forms a hypothesis that the color reaches the flower through the stem. what should maria do to confirm the hypothesis? she should repeat the experiment with the same type of flower and photograph the changes over time. she should ask her science teacher about the flower to confirm whether her hypothesis is correct. she should try the experiment with a potted plant with roots and observe any color changes. she should repeat the experiment with a different species of plant and photograph the changes.

Maria should try the experiment with a potted plant with roots and observe any color changes. This will help her conclude better about her presumed hypothesis-  that the color reaches the flower through the stem.

A potted plant is living and to carry out experiment on a living plant is the best possible way to confirm Maria's hypothesis.
