1) Put graduated cylinder on a flat-level surface 2) Get down to eye level with liquid 3) Measure from bottom of meniscus

1) find the mass of the empty cylinder 2) add the liquid and find the mass of the liquid and cylinder 3) subtract the empty mass from the mass of the liquid and cylinder

1) Find the volume of the liquid before adding the object 2) add the object to the water and measure the new volume 3) subtract the starting volume from the volume of the liquid and the object.
