Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes developing a hypothesis

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

Explanation:

To determine the part describing developing a hypothesis, we recall that a hypothesis is a testable prediction or proposed explanation for a phenomenon. In the passage, when Nancy predicted "that one pond was growing more algae because it received more runoff when it rained", this is a proposed explanation (hypothesis) for the difference in algae growth she observed. The other parts involve observation (noticing algae difference), testing (digging ravine), or a new idea (about sunlight), but the prediction about runoff as the cause is the hypothesis development.

Answer:

She predicted that one pond was growing more algae because it received more runoff when it rained.
