Ma#er  

•  Anything  that  has  mass  and  takes  up  space  •  Examples:  pencil,  leaf,  air,  water,  book  •  Things  that  are  not  ma#er:  light,  gravity,  heat

Measuring  Ma#er  

•  Measurements  help  us  understand  and  compare  objects.  

•  Mass,  volume,  and  density  are  measurements  of  ma#er

Mass  

•  Amount  of  ma#er  in  an  object  •  Measured  in  grams  (g)  •  Weight  is  the  affect  of  gravity  on  a  mass  •  Weight  of  an  object  can  change  but  the  mass  remains  constant

Volume  

•  The  amount  of  space  that  an  object  occupies  •  Measured  in  liters  (l)  •  Volume  of  a  rectangular  solid  =  l  x  w  x  h

Density  

•  The  amount  of  mass  is  in  a  certain  volume  •  Measured  in  g/liter  •  Density  =  mass/volume

CalculaKng  Density  

•  Find  the  volume  either  through  a  calculaKon  or  through  displacement  

•  Find  the  mass  by  using  a  scale  •  Calculate  the  density  by  dividing  the  mass  by  the  volume.

Physical  ProperKes  of  Ma#er  

•  CharacterisKc  that  can  be  observed  without  changing  or  trying  to  change  the  composiKon  of  a  substance  

•  Measurable

Examples  of  Physical  ProperKes  

•  Mass,  volume,  and  density    •  State  of  ma#er  (solid,  liquid,  gas)  •  Hardness  •  Color

Chemical  ProperKes  

•  A  property  of  ma#er  that  cannot  be  observed  without  changing  the  substance.  

•  The  potenKal  to  undergo  a  chemical  change  or  reacKon

Examples  of  Chemical  ProperKes  

•  Ability  to  burn  (combusKbility)    •  pH  level  (acidic  or  basic)  •  ReacKon  to  water  •  OxidaKon  –  reacKon  to  oxygen
