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. Examples of particulate-level models could include drawings, 3D ball and stick structures, or computer representations showing different substances with different types of atoms.
Assessment boundary: Assessment does not include valence electrons and bonding energy, discussing the individual ions composing complex structures, or a complete depiction of all individual atoms in a complex molecule or extended structure.
Grade 8 Science Test Questions
Released New York State Grade 8 science test questions that assess MS-PS1-1 are listed here by test and question cluster. Each link opens the question with its answer key.
Performance Level Descriptions
Every Grade 8 Science Test question on MS-PS1-1 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Interpret a model to describe the atomic composition of simple molecules.
Level 2: Interpret models to describe the atomic composition of simple molecules or extended structures.
Level 3: Develop models to describe the atomic composition of simple molecules and extended structures.
Level 4: Develop models and evaluate limitations for the models to describe the atomic composition of complex molecules and extended structures.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-PS1-1.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-PS1-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Develop models to describe the atomic composition of simple molecules and extended structures.
Disciplinary Core Ideas
- PS1.A: Structure and Properties of Matter
- Substances are made of one type of atom or combinations of different types of atoms.
- Solids may be formed from molecules or extended structures with repeating subunits (e.g., crystals).
Crosscutting Concepts
- Patterns
- Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
- Scale, Proportion, and Quantity
- Time, space, and energy phenomena can be observed at various scales.
