This is a set of assessments for MS NGSS PS-1-1-6. These assessments are aligned with NGSS Middle School Science Strand Matter and Its Interactions and it addresses all standards in this DCI. These may be used for assessment at the end of each standard being taught or for review, practice, and assessment at the end of the school year for test preparation. These assessments are in multiple-choice and short-answer formats. They come with answer keys. The standard being addressed is listed at the top of each page. These assessments are in Google Forms and a printable pdf.

Matter and Interactions NGSS PS1 Assessments

  • Printable Assessments 12 pages
  • Six Google Forms
  • Answer Keys

These assessments are aligned with the following standards:

Standards Assessed

NGSS MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.[Clarification Statement: Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds.

NGSS 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. [Clarification Statement: Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride.]


Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. [Clarification Statement: Emphasis is on natural resources that undergo a chemical process to form the synthetic material. Examples of new materials could include new medicine, foods, and alternative fuels.] [Assessment Boundary: Assessment is limited to qualitative information.]

NGSS MS PS1-4  Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. [Clarification Statement: Emphasis is on qualitative molecular-level models of solids, liquids, and gases to show that adding or removing thermal energy increases or decreases the kinetic energy of the particles until a change of state occurs. Examples of models could include drawings and diagrams. Examples of particles could include molecules or inert atoms. Examples of pure substances could include water, carbon dioxide, and helium.]

NGSS MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

NGSS MS PS1-6 Undertake a design project, engaging in the design cycle, to construct and/or implement a solution that meets specific design criteria and constraints test, and modify a device that either releases or absorbs thermal energy by chemical processes.*
