Juan's class is studying soils. Juan and his partner dug a shovel full of dirt and placed it in a jar. They added water and then covered the jar. Next, they shook the jar until everything was all mixed up. The boys put the jar on the shelf and left it until the next day. This is what they saw. What property of the soil is shown by this experiment?

Answer 1

The experiment described, where soil is mixed with water and then left to settle, primarily demonstrates A) particle size. This is because, after settling, different particle sizes will separate in layers, with larger particles settling at the bottom and finer particles remaining suspended or settling on top. Thus, the observation from the experiment relates most directly to the property of particle size.
