NGSS High School Chemistry

Summer - Fall 2026
A conceptual high-school chemistry course organized around NGSS physical science expectations for matter, reactions, and energy. Students learn chemistry as a way to explain phenomena: why substances have different properties, how atoms are rearranged during reactions, why reaction conditions matter, and how energy moves through chemical systems. Use this path when the goal is NGSS-aligned chemistry understanding with particle models, evidence-based explanations, and lighter quantitative load than AP or college chemistry.

Aligned to NGSS high-school physical science chemistry strands: structure and properties of matter, chemical reactions, and energy in chemical processes.

NGSS alignment: Coverage follows NGSS HS-PS1 and relevant HS-PS3 expectations, with science practices embedded through models, data, and explanations.
NGSS HS Physical Science: Official high-school physical science topic framework.

NGSS Chemistry Learning Outcomes

Science Practices and Particle Models

Develop and revise models, analyze data, use mathematical thinking, and construct explanations from evidence.
Use particle diagrams, symbolic representations, graphs, and lab data to explain chemical phenomena.

Structure and Properties of Matter

NGSS PS1.A
Explain atomic structure, periodic patterns, and how molecular structure determines properties.
Use the periodic table, bonding models, and structure-function reasoning to predict substance behavior.
Treat nuclear processes conceptually where they support matter, element formation, and energy-release explanations.

Chemical Reactions

NGSS PS1.B
Use conservation of atoms and mass to represent chemical change with equations and particle models.
Explain reaction rates, collision models, equilibrium ideas, and energy changes in chemical systems.
Keep design language focused on evaluating chemical systems and tradeoffs, not full project-based engineering builds.

Energy in Chemical Systems

NGSS PS3
Track energy transfer and conservation in reactions, phase changes, and everyday chemical processes.
Connect thermal energy, bond energy, system boundaries, and energy diagrams to explanations of chemical phenomena.
