• Effectively apply the analysis, synthesis, and evaluative processes that enable productive problem solving.

• Value and demonstrate personal responsibility, character, cultural understanding, and ethical behavior.

Meaning

Understandings

Students will understand…

• The particle/molecular arrangement of solids vs. liquids vs. gases.

• The relationship between temperature changes, kinetic energy, and particle arrangement of matter.

• The relationship between potential energy and phases changes.

• How temperature and pressure are related to and impact gases.

• How the arrangement of protons, neutrons, and electrons are arranged in atoms.

• How to classify matter as an atom, molecule, solution, or mixture.

• How to describe matter by utilized its physical and chemical properties.

• How to determine if a chemical change occured, and that the physical properties of the products are different than the physical properties of the reactants.

• How to separate mixtures based upon the physical and chemical properties of the individual components of the mixture.

• How to identify matter based upon it physical and chemical properties, and its ability to undergo physical and/or chemical change.

• How to determine, experimentally, the density of a regular shaped solid, irregularly shaped solid, and liquid.

• How and why the atoms of the periodic table are placed into their respective periods and families.

• The differences between the structures of atoms, molecules, and extended structures.

• How to build models for atoms, molecules, and extended structures such as diamond and sodium chloride.

• Why some atoms and molecules stick together and others do not.

• How the law of conservation of mass relates to chemical reactions.

• How synthetic materials are made from natural resources.

• How the creation of synthetic materials impact society.

• How the evaluate the credibility of a website.

Essential Questions

Students will keep considering…

• How does the behavior of substances depend on the their structures and atomic and molecular levels?

• How does a change in properties of a substance relate to the rearrangement of atoms in the reactants and products of a chemical reaction?

• How do pressure, temperature, energy, and state of matter interrelate?
• How do chemical reactions relate to the law of conservation of mass?
• How are synthetic materials formed from natural resources and how do they impact society?

Acquisition

Students will know…

• The three main states of matter are solid, liquid, gas.

• The phase changes between the states of matter: boiling, condensing, melting, freezing.

• Atoms are composed of protons, neutrons, and electrons.

• Matter can be classified as a pure substance (atom or molecule) or mixture (solution or heterogeneous mixture).

• Physical and chemical properties describe matter.

• Density, mass, volume, odor, solubility, and phase change points are physical properties.

• Flammability is a chemical property.

• Filtration, magnetism, and evaporation are separation techniques.

• Atoms are arranged systematically in the periodic table.

• The periodic table is separated by the staircase into metals and nonmetals with metalloids bordering the staircase.

• Pure substances can form extended structures.

• The law of conservation of mass.

• Synthetic material.

• Natural Resource.

• Atoms can bond ionically or covalently.

• Ionic Bond.

• Covalent Bond.

• Valence electron.

Students will be skilled at…

• Develop models to describe the atomic composition of simple molecules and extended structures.
• Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
• Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
• 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.
• 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.
