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. ted loves doing experiments in his kitchen, especially ones that involve fun reactions. one day, he mixed baking soda and vinegar to create fizzy foam. he wondered if the diameter of the container where he mixed the ingredients affected how high the foam could rise. ted thought that the diameter of the container shouldnt matter; it is the ingredients themselves that determine the height of the foam. ted found three containers with different diameters: a narrow glass, a wider jar, and an even wider bowl. he added the same amount of baking soda and vinegar to each container. ted then used a ruler to measure the height of the foam produced. he found that the foam in the wide bowl was the shortest, while the foam in the narrow glass was the tallest. he now predicted that a taller, narrower container allowed the foam to rise higher because it provided less surface area for the foam to spread out. the next week, ted shared his results with his science club at school.

Explanation:

The key - part is where Ted makes a new prediction based on his experiment results. He initially thought container diameter didn't matter, but after seeing the foam heights in different containers, he formed a new idea. The statement "He now predicted that a taller, narrower container allowed the foam to rise higher because it provided less surface area for the foam to spread out" shows him revising his hypothesis.

Answer:

He now predicted that a taller, narrower container allowed the foam to rise higher because it provided less surface area for the foam to spread out.
