QuestionIn 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 shoutd ask her science teacher about the fower 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.
Studdy Solution
STEP 1
1. Maria's hypothesis is that the color reaches the flower through the stem.
2. To confirm a hypothesis, an experiment must be designed that isolates the variable of interest (in this case, the stem) and observes its effects.
3. Maria must ensure that the experiment is controlled and repeatable to validate her hypothesis properly.
STEP 2
1. Design a controlled experiment to test the hypothesis.
2. Observe and document the results.
3. Compare the outcomes to determine if they support the hypothesis.
STEP 3
Design a controlled experiment to test the hypothesis that the color reaches the flower through the stem.
STEP 4
To confirm the hypothesis, Maria should use a similar setup but include different conditions to analyze the role of the stem in color change. For instance, she could repeat the experiment with a potted plant with roots to see if the color change still occurs and observe any color changes.
STEP 5
Observe and document the results by photographing the changes in the flower petals over time. This will provide visual evidence of the color change process and help in comparing with other setups.
STEP 6
Compare the results of the experiment with the potted plant to the original experiment to see if the color reaches the flowers through the stem in both cases. This comparison will help in determining if the hypothesis is supported.
Thus, the correct option is:
C. She should try the experiment with a potted plant with roots and observe any color changes.
