The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea
The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea Physical Science the study of matter and energy. Studying Physical Science Physical science is the study of matter and energy Physical science has two main branches Chemistry is the study of the structure and makeup of matter and changes matter undergoes Physics deals with energy and matter and how they interact Specialization Specialization is working in one area of a subject Specialized fields of physical science include biochemistry, thermodynamics, optics, and nuclear physics Importance of Physical Science Discoveries of physical scientists are important in everyday life Physical scientists have researched nuclear energy to reduce world’s energy problems Studying matter and how it reacts with other substances has created new materials for everyday life. Physical scientists are researching other alternative sources of energy Discovery of new materials has resulted in development of plastics, ceramics, and other products
The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea Properties of Matter the characteristics used to describe an object. Matter Matter is anything that has mass and takes up space Mass is amount of matter a sample contains Volume is amount of space sample takes up Properties of Matter Properties are characteristics used to describe an object Properties include color, shape, hardness, mass, volume, weight, and density Weight is measure of pull of gravity on sample of matter Density tells how much matter is in a unit volume Physical Sciences Chemistry is study of structure and makeup of matter and changes matter undergoes Chemists study how different kinds of matter change and combine Physics is the study of ways that different forms of energy and matter interact Physicists study the different forms of energy Physical scientists study the properties of matter and energy.
The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea Changes in Matter distinguishing between physical and chemical changes. Physical Properties Physical properties can be observed or measured without changing makeup of substance States of matter are physical properties Physical properties include shape, size, color, and texture Physical Changes Chemical Changes Physical change does not produce new substances Physical changes involves physical properties of material Chemical change results in new kind of matter being formed E.g., sawing of wood, cutting apple in half E.g., burning wood, rusting of iron, digesting food Changes in matter can be either physical or chemical.
The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea State Changes ways in which matter can change from one state to another. State Changes A change in matter from one state to another Four main kinds of change of state During change of state, there is change in heat energy Substance gains or loses heat during state change Freezing & Melting Evaporation & Condensation Sublimation Freezing is change from liquid to solid At freezing point, liquid loses enough heat to change to solid Melting is change from solid to liquid At melting point, solid gains enough heat to change to liquid When matter changes from one state to another, a substance gains or loses heat energy. Evaporation is change from liquid to gas at surface of liquid Particles at surface gain enough heat to change to gas state Condensation is change from gas to liquid Particles in gas lose heat energy and change into liquid Sublimation is change of a solid directly to a gas without passing through liquid state Sublimation point is temperature at which solid changes to gas
The FRAME Routine Key Topic is about… So What? (What’s important to understand about this?) Main idea States of Matter the four physical forms, or states, of matter. SolidLiquidGasPlasma State of matter with definite shape and volume Particles are tightly packed Particles can only vibrate in place Cannot change position easily State of matter with definite volume but no definite shape Particles can change position Particles take shape of container State of matter with no definite shape or volume Particles are in constant motion Particles take shape of container Particles move to all parts of container Rare on earth State of matter made of electrically charged particles Found where temperatures and pressures are high-stars Scientists have created plasmas in laboratory All matter can exists in one of four states: solid, liquid, gas, or plasma.
