Question

scientific inquiry. select the part of the passage that describes developing a hypothesis.
a foamy mixture of baking soda and vinegar
dustin 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. dustin thought that the diameter of the container shouldnt matter; it is the ingredients themselves that determine the height of the foam. dustin 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. dustin 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, dustin shared his results with his science club at school.

Explanation:

Una hipótesis es una suposición o idea que se formula para explicar un fenómeno o responder a una pregunta en un estudio científico. En este caso, la idea de Dustin de que el diámetro del recipiente no importa y que son los ingredientes los que determinan la altura de la espuma es una hipótesis. Es una declaración que se hace antes de realizar la experimentación y que se puede probar o refutar a partir de los datos obtenidos.

Answer:

Dustin thought that the diameter of the container shouldn't matter; it is the ingredients themselves that determine the height of the foam.
