The two plastic weighing buckets, which are marked to enable measurements to 500 mL, can hold liquid or solid samples, and are easy to remove for pouring samples, cleaning, and storing. There are dual pointers on either side of the balance base that enable students to view readings from both sides of it. This balance includes a guide with 16 educational activities to help teachers demonstrate measuring concepts using common liquids and solids.
