That's a tough one! I'm also a native Spanish speaker and I imagine that the usage of these words poses the same kind of difficulty for English speakers that "do" and "make" represent for us.
I think we use "ser" for those characteristics that define a person /object permanently:
"Soy argentina"
"Soy de Boca" (I'm not, actually!)
"Soy impaciente"
whereas "estar" is used for transient states or qualifiers:
"Estoy cansada"
"Los ladrones estaban arrepentidos"
"La casa está sucia"
Tell your friend to note the difference between:
"El perro es nervioso" (permanent character)
and
"El perro está nervioso"
Estar is also the verb to use with circumstantials (of place, time, etc):
"Están en el parque"
"Estaremos con mis amigos"
while "ser" is the auxiliary for passive voice:
"Martín fue atacado por un perro"
Here's a couple of webpages with lessons on usage of these verbs:

http://www.bowdoin.edu/~eyepes/newgr/gra… (this one has a table with usage definitions)
Hope this helps!
PS I'm also curious about the explanation that a native English speaker would give, so I'll check back :-)
