1. Sig Digs Lab Practice – Rd 2
At your lab station you have a piece of Zinc.
Think about what you would need to do to
determine the density of the Zinc both by
linear measurement and by volume
displacement.
Set up a data table.
(Show units and correct sig digs in your
measurements & calculations.)
(Tilt & Slide…NO BOMBS AWAY)
