You would see an oxidation reduction reaction occur in the beaker.

The net ionic form of this reaction would be:
Zn(s)+Cu2+(aq)Zn2+(aq)+Cu(s)

Let's break this equation into half-reactions to explain what is happening.

The zinc is being oxidized and replaces the Cu2+(aq) in solution:
Zn(s)Zn2+(aq)+2e

The copper is reduced and replaces the Zn(s) on the zinc rod:
Cu2+(aq)+2eCu(s)

Notice : The 2 electrons lost in the oxidation of the zinc metal allow for the copper to be reduced.
