I think that Clark and Pa Kent are unsure about Clark’s age because he was found in a rocket as a baby.  So Pa Kent doesn’t have an actual birthdate for Clark.  Clark’s powers are uncertain because he is from another planet and no one on this planet knows anyone form that planet so there isn’t anyone to use as a point of reference to determine what Clark’s powers could possibly be. I think Pa Kent and Martha are concerned with how Clark is dealing with the realization of his powers and the fact that he is different from all the other kids that he knows. They see him as withdrawing as evident in the dinner conversation with Lana.
