Question

1. which of the following is not a constant in this experiment? choose all that apply.

the pots the bean sprouts were placed in
the sunny window sill
the amount of water
the ph of the soil
the length of the experiment
the height of the bean sprouts
the amount of vinegar - water mixture

Explanation:

In an experiment, a constant is a factor that remains the same throughout. The height of the bean - sprouts is a variable that is likely to change as the experiment progresses. The amount of water, the pH of the soil, the length of the experiment, and the amount of vinegar - water mixture could potentially be varied or are the results of the experiment, so they are not constants. The pots and the sunny window sill are likely to be kept the same and can be considered constants.

Answer:

The amount of water, The pH of the soil, The length of the experiment, The height of the bean sprouts, The amount of vinegar - water mixture
