All of these answers are technically right but not complete. Polarity comes from assymetry and electronegativity. If there is a difference between electronegativity and the molecule is assymetrical, then it's polar. I'm a synthetic organic chemist and I can tell you for certain that it has absolutely nothing to do with reactivity.

Polar molecules are stable; non-polar molecules easily react with others & form other compound. Therefore if a molecule is stable for long it is polar, if it reacts with other molecule to form a stable compound it is non-polar.

See if it dissolves significantly in water. Polar molecules will, non-polar molecules won't.

Well, if you're building a model or something, you have to see if its symmetrical, or unsymmetrical. If its symmetrical, then the molecule is nonpolar, if it is unsymmetrical it is polar.
ex. Like linear and tetrahedral molecules are nonpolar, because they're symmetrical.
