The correct approach for Debbie to determine whether the piece of plastic would float or sink without actually placing it in water is:

C. find the density of the plastic and compare it to the density of water.

An object will float in water if its density is less than the density of water (which is approximately 1 g/cm³ at room temperature). If the density of the plastic is greater than that of water, it will sink.
