How do balance scales work?
In simple terms, a balances measure mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.

A spring scale measures weight or force when an object is hung from its hook. To measure loose material such as sand, pour into a plastic bag and hang the bag from the hook. This one has a dual scale that reads 0-1000 g in 10 g increments and 0-10 Newtons in 0.1 Newton increments.
