Question

variables hw check
which statement is the best example of a testable hypothesis?
sunlight is good for plants.
plants need water and soil.
plants are pretty.
if plants get more sunlight, then they will grow taller.

Explanation:

A testable hypothesis has variables that can be manipulated and measured. "If plants get more sunlight, then they will grow taller" has an independent variable (amount of sunlight) and a dependent variable (plant height) which can be tested. "Sunlight is good for plants" and "Plants need water and soil" are too general and lack specific testable relationships. "Plants are pretty" is a subjective statement and not testable scientifically.

Answer:

If plants get more sunlight, then they will grow taller.
