Question

How would a scientist properly execute the water displacement method in an experiment to find the volume of a small rock?




Place a rock in a container, add water, and record the volume.



Pour an unknown amount of water into a glass container, add the rock, and note the water level; the unknown amount of water plus the weight of the rock is the volume of the rock.
