Introduction to Matter Review

We recap Unit 2," Introduction to Matter," in which we covered crosscutting concepts that are used by scientists around the world and looked at the chemical and physical properties of matter. We watched a scientist demonstrate phase changes from solid to liquid to gas in our studio, using liquid nitrogen.

Georgia Standards of Excellence

SC2Obtain, evaluate, and communicate information about the chemical and physical properties of matter resulting from the ability of atoms to form bonds.

SC2.aPlan and carry out an investigation to gather evidence to compare the physical and chemical properties at the macroscopic scale to infer the strength of intermolecular and intramolecular forces.

SC2.bConstruct an argument by applying principles of inter- and intra- molecular forces to identify substances based on chemical and physical properties.

SPS5Obtain, evaluate, and communicate information to compare and contrast the phases of matter as they relate to atomic and molecular motion.

SPS5.aAsk questions to compare and contrast models depicting the particle arrangement and motion in solids, liquids, gases, and plasmas.

SPS6Obtain, evaluate, and communicate information to explain the properties of solutions.

SPS6.aDevelop and use models to explain the properties (solute/solvent, conductivity, and concentration) of solutions.

SPS6.bPlan and carry out investigations to determine how temperature, surface area, and agitation affect the rate a solute dissolves in a specific solvent.

SPS6.cAnalyze and interpret data from a solubility curve to determine the effect of temperature on solubility.

SPS7Obtain, evaluate, and communicate information to explain transformations and flow of energy within a system.

SPS7.dAnalyze and interpret data to explain the flow of energy during phase changes using heating/cooling curves.

S8P1Obtain, evaluate, and communicate information about the structure and properties of matter.

S8P1.aDevelop and use a model to compare and contrast pure substances (elements and compounds) and mixtures. (Clarification statement: Include heterogeneous and homogeneous mixtures. Types of bonds and compounds will be addressed in high school physical science.)

S8P1.bDevelop and use models to describe the movement of particles in solids, liquids, gases, and plasma states when thermal energy is added or removed.

S8P1.cPlan and carry out investigations to compare and contrast chemical (i.e., reactivity, combustibility) and physical properties of matter (i.e., density, melting point, boiling point).

S8P1.dConstruct an argument to support the claim that when a change occurs it is either chemical or physical. (Clarification statement: Evidence could include ability to separate mixtures, development of a gas, formation of a precipitate, change in energy, color, and/or form.)
