Keep Your Masses Balanced

This isn’t one of those antique scales of justice you see in law office logos, but it works like one. Technically a “balance,” ours is plastic, from SI Manufacturing, and just right for middle-schoolers. Measures 12” wide x 5-1/4” deep x 4-1/2” tall. Has a 10g beam for fine adjustments, accurate to .5g, (2) removable pans that are 4-1/4" square at their base and 4-11/16" on top with 1" high sides, and a (7)-piece brass mass set that fits in holes in the base of the balance—(2) at 50g, (2) at 20g, and (3) at 10g. Includes an activity guide with several experiments for students to learn about balances and mass. Also has a centering slide weight on back to zero the balance. Please unpack carefully; this is a finely tuned machine, like you.
