How do we gain scientific knowledge?
Andie's science fair project was to study if plants can help keep a house cool. Her results failed to support her hypothesis. How does this
reflect on her original experiment?
A The experiment was not useful, because the results did not support the hypothesis.
B. The experiment was useful because Andie learned more about plants and can now do further investigation.
C. The experiment was not useful because Andie did not get a good grade on her project.
D. The experiment was useful because if Andie redoes it, she will likely get different results.
