In middle school, students develop an understanding of the disciplinary core ideas in the physical science domain. The middle school performance expectations build on the elementary performance expectations and allow students to explain concepts that are important not only to physical science, but also to life science and the earth and space sciences. In PS2: Motion and Stability: Forces and Interactions, performance expectations are designed for students to create an understanding of how different types of forces interact to create motion. Students should demonstrate an understanding of how action-reaction, gravitational, electrical, and magnetic forces cause motion.
In high school, students continue to develop and refine their understanding of physical science concepts. The high school performance expectations are meant to expand on the middle school performance expectations. The high school performance expectations cover fundamental concepts of chemistry and physics, while leaving room for more expanded and in-depth study in upper level high school courses. As in middle school, physical sciences concepts are also important for understanding life and Earth and space sciences. Performance expectations in high school PS2: Motion and Stability: Forces and Interactions call for students to apply knowledge in order to predict interactions between objects and within systems. More advanced concepts in this core idea include the relationships between force and mass and how these relate to acceleration, momentum, and gravitation.
