Query: wide age bracket appropriate

The magic school bus series seems to be written for a 4-5 year old while containing material appropriate for a ten year old. The books seem very complete and well written but there is a very wide age range that they seem to be written for. Seem to be very good for a VERY advanced child but not for the normal 4 or 5 year old.
