MA STE Frameworks

In 7th grade, students explore natural and designed systems and cycles, some that are concrete and easily observable and others that are more abstract across nine month-long units. They use their knowledge of Earth systems, ecosystem dynamics, energy systems, and technological systems to answer real-world questions and solve real-world problems.
