O Air bubbles adhered to the metal when measuring the volume.
O The weigh boat was not tared (zeroed) before measuring the mass of the metal.
O The graduated cylinder was not completely dry and had some excess water inside.
O The student measured the volumes above the meniscus
O The student did not take the inverse of the slope.
O Water splashed out of the graduated cylinder before the metal was added.
