Third, family socio-economic status in the 7th grade has positive effects on natural science learning motivation in the subsequent five semesters. Fourth, family cultural capital in the 7th grade has positive effects on the junior high school students' natural science learning motivation. Fifth, family cultural capital in the 7th grade has positive effects on the learners' natural science learning motivation in the subsequent five semesters. Sixth, the 7th graders' interest in natural science has positive effects on their natural science learning motivation, and their interest in natural science in the 7th grade has positive effects on natural science learning motivation in the subsequent five semesters.
