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 PS1: Matter and Its Interactions, performance expectations are designed for students to create an understanding of the structure and properties of matter at the atomic and bulk scales. Students should also understand what occurs in chemical reactions, in terms of the rearranging of atoms to form different substances.

 

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 PS1: Matter and Its Interactions are designed for students to build a more in-depth understanding of the structure, properties, and interactions of matter. By the end of high school, students should understand aspects of chemical reactions such as rate and equilibrium, radiochemistry, and relationships to biology and geology.

 

PS1: Matter and its Interactions

Middle School

MS-PS1-1 Develop models to describe the atomic composition of simple molecules and extended structures.

MS-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

 

PS1: Matter and its Interactions

High School

HS-PS1-1 Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

HS-PS1-2 Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

HS-PS1-3 Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
