Quarter 2



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

PS1-MS-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-MS-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.

PS1-MS-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.


Disciplinary Core Ideas

  • PS1.A: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. (PS-MS-1) - Actions: Develop models
  • PS1.A: Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. (PS1-MS-2) - Actions: Analyze and interpret data
  • PS1.A: In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations. (PS1-MS-4) - Actions: Develop a model
  • PS1.B: Chemical Reaction: Substances react chemically in characteristic ways and these new substances have different properties from those of the reactants. (PS1-MS-1, PS1-MS-2, PS1-MS-5) - Actions: Develop models, analyze and interpret data, develop and use a model
  • PS3.A: Heat refers to the transfer of thermal energy from one object to another. (PS1-MS-4) - Actions: Develop a model


Disciplinary Core Ideas

  • PS1.A: Gasses and liquids are made of molecules or inert atoms that are moving about relative to each other.
  • PS1.A: In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.
  • PS1.A: The changes of state that occur with variation in temperature can be described and predicted using these models of matter (solid, liquid, gas).
  • PS1.B: The total amount of matter is not created or destroyed thus the mass does not change.
  • PS1.B: Some chemical reactions release energy, others store energy.
  • PS3.A: The thermal energy of a system depends jointly on the temperature, the total number of atoms in the system, and the state of the material.
  • ETS1.A: A solution needs to be tested, and then modified on the basis of the test results to improve it.

RST.6-8.1 Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions (PS1-MS-2),(PS1-MS-3)

RST.6-8.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks. (PS1-MS-6)

RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). (PS1-MS-1),(PS1-MS- 2),(PS1-MS-4),(PS1-MS-5)

WHST.6-8.7 Conduct short research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions that allow for multiple avenues of exploration. (PS1-MS-6)

WHST.6-8.8 Gather relevant information from multiple print and digital sources, using search terms effectively; assess the credibility and accuracy of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism and following a standard format for citation. (PS1-MS-3)


MP.2 Reason abstractly and quantitatively. (PS1-MS-1),(PS1-MS-2),(PS1-MS-5)

MP.4 Model with mathematics. (PS1-MS-1),(PS1-MS-5)

6.RP.A.3 Use ratio and rate reasoning to solve real-world and mathematical problems. (PS1-MS-1),(PS1-MS- 2),(PS1-MS-5)

6.NS.C.5 Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation. (PS1-MS-4)
