Excellent!  Could you filter that list to show only the students who were taught by the teacher with the last name Moyer?
SELECT T1.firstname ,  T1.lastname FROM list AS T1 JOIN teachers AS T2 ON T1.classroom   =   T2.classroom WHERE T2.lastname   =   "MOYER"
filtering by teacher's last name = WHERE condition on teacher's last name; list of students = SELECT statement specifying student names; joining tables on classroom = JOIN clause based on classroom match;
