Why is a water molecule polar?

Because of its shape. it is a bend molecule.

Since Oxygen is more electronegative that hydrogen, you get something called a net dipole making the oxygen "delta" negative. this makes the hydrogen delta positive since the oxygen atom is more electronegative ( i like to think of it as being "hungry for electrons" or a selfish atom that hogs the electrons), the electrons spend more time orbiting the oxygen that it does the hydrogens. therefore the oxygen is slightly (or delta) negative and the Hydrogen, since the electrons spend less time in orbit around the hydrogen, is delta (slightly )positive since an electron has a negative charge.
