Transcript of "7th Grade Chapter 4 Lesson 1"

  1. 1. Pgs. 125-133 For Student Use Only
  2. 2. Matter <ul><li>Matter is all substances God created. </li></ul><ul><ul><li>Material things are made up of matter </li></ul></ul><ul><ul><li>God is immaterial= not made of matter </li></ul></ul><ul><ul><li>Materialism- philosophy that states that nothing is real unless it is physical or material </li></ul></ul><ul><li>Three states of Matter </li></ul><ul><ul><li>Solid </li></ul></ul><ul><ul><li>Liquid </li></ul></ul><ul><ul><li>Gas </li></ul></ul>
  3. 3. Matter <ul><li>States of Matter: </li></ul><ul><ul><li>Solid- definite shape and volume </li></ul></ul><ul><ul><ul><li>Atoms arranged close together </li></ul></ul></ul><ul><ul><li>Liquid- definite volume but NO shape </li></ul></ul><ul><ul><ul><li>Atoms are arranged loosely </li></ul></ul></ul><ul><ul><li>Gas- NO definite volume and NO definite shape </li></ul></ul><ul><ul><ul><li>Atoms are arranged far apart </li></ul></ul></ul>
  4. 4. Matter <ul><li>Changing states: </li></ul><ul><ul><li>Matter will change from one state to another. </li></ul></ul><ul><ul><ul><li>Solid to liquid= melting </li></ul></ul></ul><ul><ul><ul><li>Liquid to gas= evaporation </li></ul></ul></ul><ul><ul><ul><li>Liquid to solid= freezing </li></ul></ul></ul><ul><ul><ul><li>Gas to liquid= condenstion </li></ul></ul></ul><ul><ul><ul><li>Solid to gas= sublimation (dry ice= CO 2 ) </li></ul></ul></ul>
  5. 5. Matter <ul><li>Physical Properties: </li></ul><ul><ul><li>Physical Properties- properties that can be determined without changing into a different substance </li></ul></ul><ul><ul><ul><li>Examples: </li></ul></ul></ul><ul><ul><ul><ul><li>Temperature </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Odor </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Color </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Density </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Ability to be dissolved </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Conductivity </li></ul></ul></ul></ul>
  6. 6. Matter <ul><li>Physical Properties: </li></ul><ul><ul><li>Quantification: </li></ul></ul><ul><ul><ul><li>The systematic process of accurately measuring the things of nature and their parts </li></ul></ul></ul>
  7. 7. Matter <ul><li>We measure: </li></ul><ul><ul><li>Temperature= how hot or cold something is </li></ul></ul><ul><ul><ul><li>Freezing point= temperature at which liquid turns into a solid </li></ul></ul></ul><ul><ul><ul><li>Boiling point= temperature at which liquid turns into a gas </li></ul></ul></ul><ul><ul><ul><li>Use a thermometer </li></ul></ul></ul><ul><ul><ul><li>Use °C or °F </li></ul></ul></ul><ul><ul><li>Solubility </li></ul></ul><ul><ul><ul><li>The ability to be dissolved </li></ul></ul></ul><ul><ul><ul><li>Higher temperature= more substance dissolved </li></ul></ul></ul><ul><ul><ul><li>Insoluable= not able to be dissolved </li></ul></ul></ul>
  8. 8. Matter <ul><li>We measure: </li></ul><ul><ul><li>Mass: </li></ul></ul><ul><ul><ul><li>The quantity or amount of something </li></ul></ul></ul><ul><ul><li>Weight </li></ul></ul><ul><ul><ul><li>The measure of the force of gravity pulling down on an object </li></ul></ul></ul><ul><ul><li>Weight and mass are related </li></ul></ul><ul><ul><ul><li>More Mass= More Weight </li></ul></ul></ul>
  9. 9. Matter <ul><li>We measure: </li></ul><ul><ul><li>Density: </li></ul></ul><ul><ul><ul><li>The mass of a substance divided by its volume </li></ul></ul></ul><ul><ul><ul><li>Every substance has a different density </li></ul></ul></ul><ul><ul><ul><ul><li>Units= g/cm 3 or g/mL </li></ul></ul></ul></ul><ul><ul><ul><li>Different objects have different densities </li></ul></ul></ul><ul><ul><ul><li>Densities change from state to state </li></ul></ul></ul><ul><ul><ul><ul><li>Solids are typically more dense than liquids and gases </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Water is special- ice less dense than water (water molecules have special arrangement) </li></ul></ul></ul></ul>
