about 0.45 g/cm3.
Note: Answers will vary but the calculated density of the wood will generally be less than the
calculated density of the vinegar.

Answers will vary but the wood will float if less
dense than the vinegar.
Use your observations to write an operational definition of density in the
space below.
Answers will vary. Sample answer: Density determines if an object will sink or float. It can be
calculated by dividing the object’s mass by its volume. It measures how tightly the matter in each
