Answer:
The time it takes particles to form sediment on the bottom of a containers
Explanation:
The dependent variable would be <u>the time it takes different particle sizes to settle out of water in order to form sediment on the bottom of containers.</u>
<em>The dependent variable is an experimental variable whose value varies according to the independent variable supplied by the researcher during the course of an experiment. The value either increases or decreases with each value of the independent variable. </em>
In order to answer the question in the illustration, different particle sizes would have to be supplied by the student as an input - the independent variable - and the time it takes for each particle size to settle and form sediment recorded - the dependent variable.
Water vapor
