Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis. hint: to revise the hypothesis, you use the results of the investigation to come up with a new explanation. algae growing on a pond britney has two small ponds on her farm. she noticed that one pond was growing algae while the other was not. she wondered what could be causing the difference in algae growth in her ponds. she predicted that one pond was growing more algae because it received more runoff when it rained. to test this, britney dug a small ravine to catch runoff, ensuring that it didnt flow into either pond. after one month, she reassessed the algae growth. she found that the algae growths had not changed; one pond was still growing more algae than the other. britney thought that since one pond was in direct sunlight, the sunlight may be killing algae growths.

Explanation:

Britney first hypothesized runoff as the cause of differential algae - growth. After testing and finding no change, she proposed a new explanation (sunlight killing algae) based on the results of her investigation. This new explanation is the revised hypothesis.

Answer:

Britney thought that since one pond was in direct sunlight, the sunlight may be killing algae growths.
