8th Grade Massachusetts Curriculum

In 8th grade, students explore more complex phenomena, systems, and cycles. As scientists and engineers, students analyze patterns and make predictions about future events as they investigate real-world phenomena and designed processes across nine month-long units that integrate life science, Earth and space sciences, physical science, and technology/engineering.
