Question

Jada is interested in studying whether her grass will feel softer if she mows the grass every 5 days or every 7 days. She guesses that if she mows it more often the grass will have sharp, ragged edges on it more often; she thinks waiting 7 days will produce softer grass. In the summer of 2020, she mows the grass every 5 days and asks people how her grass feels on their feet. In the summer of 2021, she mows the grass every 7 days. More people reported soft grass in 2021. 2. a)What is the independent variable for the experiment?

Answer 1

The independent variable for Jada's experiment is the frequency of mowing the grass, which he tested by mowing the grass every 5 days in 2020 and every 7 days in 2021. Based on the feedback from more people reporting soft grass in 2021, Jada's hypothesis seems to be supported.

Step-by-step explanation:

The independent variable for Jada's experiment is the frequency of mowing the grass, which means the number of days she waits before mowing the grass.

In this experiment, Jada mowed the grass every 5 days in the summer of 2020 and every 7 days in the summer of 2021 to compare the softness of the grass. By changing the frequency of mowing, she is testing how it affects the grass's texture.

Jada hypothesized that waiting 7 days between each mowing would produce softer grass. Based on the feedback from more people reporting soft grass in 2021, her hypothesis seems to be supported.
