Question

In science class, Maria observes a white-colored cut flower. She sees that the petals turn red when the flower is sitting in a vase that has red-colored water.

She forms a hypothesis that the color reaches the flower through the stem. What should Maria do to confirm the hypothesis?

A.
She should repeat the experiment with the same type of flower and photograph the changes over time.
B.
She should ask her science teacher about the flower to confirm whether her hypothesis is correct.
C.
She should try the experiment with a potted plant with roots and observe any color changes.
D.
She should repeat the experiment with a different species of plant and photograph the changes.

Answer 1

A. She should repeat the experiment with the same type of flower and photograph the changes over time.

Answer 2

C. She should try the experiment with a potted plant with roots and observe any color changes.

Answer 3

To confirm her hypothesis that the color reaches the flower through the stem, Maria should try the experiment with a potted plant with roots and observe any color changes. This will allow her to compare the results with her original observation and determine if the stems of the plant are indeed responsible for carrying the color to the petals. By conducting the experiment on a potted plant with roots, Maria can test if the color from the water can still reach the petals without the stem acting as a pathway. This will help her draw a more accurate conclusion about her hypothesis. Therefore, the correct answer is option C: she should try the experiment with a potted plant with roots and observe any color changes.
