2the study of matter and energy. The FRAME RoutineKey Topicis about…So What? (What’s important to understand about this?)Main ideaPhysical Sciencethe study of matter and energy.Studying Physical ScienceImportance of Physical ScienceSpecializationPhysical science is the study of matter and energySpecialization is working in one area of a subjectDiscoveries of physical scientists are important in everyday lifePhysical science has two main branchesSpecialized fields of physical science include biochemistry, thermodynamics, optics, and nuclear physicsPhysical scientists have researched nuclear energy to reduce world’s energy problemsChemistry is the study of the structure and makeup of matter and changes matter undergoesPhysical scientists are researching other alternative sources of energyPhysics deals with energy and matter and how they interactDiscovery of new materials has resulted in development of plastics, ceramics, and other productsStudying matter and how it reacts with other substances has created new materials for everyday life.
3the characteristics used to describe an object. The FRAME RoutineKey Topicis about…So What? (What’s important to understand about this?)Main ideaProperties of Matterthe characteristics used to describe an object.Properties of MatterPhysical SciencesMatterMatter is anything that has mass and takes up spaceProperties are characteristics used to describe an objectChemistry is study of structure and makeup of matter and changes matter undergoesMass is amount of matter a sample containsChemists study how different kinds of matter change and combineProperties include color, shape, hardness, mass, volume, weight, and densityVolume is amount of space sample takes upWeight is measure of pull of gravity on sample of matterPhysics is the study of ways that different forms of energy and matter interactDensity tells how much matter is in a unit volumePhysicists study the different forms of energyPhysical scientists study the properties of matter and energy.
4distinguishing between physical and chemical changes. The FRAME RoutineKey Topicis about…So What? (What’s important to understand about this?)Main ideaChanges in Matterdistinguishing between physical and chemical changes.Physical PropertiesPhysical ChangesChemical ChangesPhysical properties can be observed or measured without changing makeup of substancePhysical changes involves physical properties of materialChemical change results in new kind of matter being formedPhysical change does not produce new substancesE.g., burning wood, rusting of iron, digesting foodStates of matter are physical propertiesPhysical properties include shape, size, color, and textureE.g., sawing of wood, cutting apple in halfChanges in matter can be either physical or chemical.
5ways in which matter can change from one state to another. The FRAME RoutineKey Topicis about…So What? (What’s important to understand about this?)Main ideaState Changesways in which matter can change from one state to another.Evaporation & CondensationState ChangesFreezing & MeltingSublimationA change in matter from one state to anotherFreezing is change from liquid to solidEvaporation is change from liquid to gas at surface of liquidSublimation is change of a solid directly to a gas without passing through liquid stateAt freezing point, liquid loses enough heat to change to solidParticles at surface gain enough heat to change to gas stateSublimation point is temperature at which solid changes to gasFour main kinds of change of stateDuring change of state, there is change in heat energyMelting is change from solid to liquidCondensation is change from gas to liquidSubstance gains or loses heat during state changeAt melting point, solid gains enough heat to change to liquidParticles in gas lose heat energy and change into liquidWhen matter changes from one state to another, a substance gains or loses heat energy.
6the four physical forms, or states, of matter. The FRAME RoutineKey Topicis about…So What? (What’s important to understand about this?)Main ideaStates of Matterthe four physical forms, or states, of matter.SolidLiquidGasPlasmaState of matter with definite shape and volumeState of matter with definite volume but no definite shapeState of matter with no definite shape or volumeState of matter made of electrically charged particlesParticles are in constant motionParticles are tightly packedParticles can change positionRare on earthParticles can only vibrate in placeParticles take shape of containerParticles take shape of containerFound where temperatures and pressures are high-starsCannot change position easilyParticles move to all parts of containerScientists have created plasmas in laboratoryAll matter can exists in one of four states: solid, liquid, gas, or plasma.
