Use a triple-beam balance and the Mix and Match Mass document to measure and record the mass of common
objects. (Ex. ice cube & ice cube melted, 5 crackers whole & 5 crackers crushed; 1 gram of salt mixed in 5 ml of water
& 1 gram of salt and from 5 ml of water; etc.)
Explain the different methods of determining volume depending on the shape of the object.

Critical Writing Prompt:
Real or Fake? Ask students if they know how
to tell if gold is “real” or if it is something else
such as “fool’s gold”. Tell them that many
jewelry stores in the U.S. sell fool’s gold as
real gold. One method of determining real
gold from something else is to know its
density. The density of real gold is (19.3
g/cm3). Have them write down ideas on how
they would test their own jewelry to
determine if it is made of real gold or not.
