From large hanging weights to precision masses with accuracy to 0.01 gram, find weights and mass sets to meet your science lab needs. For elementary students, we recommend the mass cube set (perfect for learning about both mass and volume) or hexagon mass set. For more accurate measurements for older students, get the advanced mass set. Use these for general projects or with one of our balances and scales.
