  3. 3. Aristotle’s  Free  Fall  ! The  great  Aristotle  got  some  of  his  theories  incorrect,  but   most  of  them  were  right,  and  he  changed  the  world.  ! Aristotle  said  that  heavier  objects  fell  faster  than  lighter   objects.  Galileo  tested  it,  and  discovered  that  Aristotle  was   wrong.  Gravity  effects  everything  the  same.  ! Because  of  our  greater  understanding  of  gravity,  we  will  be   able  to  discover  more  things  with  our  knowledge.  We  have   traveled  to  the  moon  and  back,  and  perhaps  may  go  even   further  next  time.  Here’s  a  video:  
  4. 4. Aristotle’s  Free  Fall  
  5. 5. Aristotle’s  Flotation  ! Aristotle  said  that  shape  alone  effects  whether  something   floats.  To  float,  an  object  must  be  thin,  flat  and  smooth,  or  a   smooth  sphere.  ! Galileo  tested  this  theory.  He  said  that  an  object  must  be   less  dense  than  water  to  float,  and  he  was  right.  ! Because  Galileo  did  this,  we  are  now  able  to  make  floating   pool  toys  and  boats.  Columbuss  and  Cook’s  boats  were   made  of  wood.  Wood  floats.  Their  discovery  changed  the   world,  and  Galileo  secretly  helped  them  to  victory.  
  6. 6. Aristotle’s  Floatation  
  7. 7. The  Telescope  ! In  1609  a  man  named  Hans  Lippershey  invented  the  telescope.  It   could  see  objects  that  appeared  to  be  a  few  steps  away,  and  the   image  was  up-­‐side-­‐down.  ! Galileo  decided  he  could  improve  the  telescope,  and  he  did.  His   was  much  more  powerful,  and  the  picture  was  not  up-­‐side-­‐down.  ! With  the  telescope,  people  could  know  if  an  army  was  attacking,   or  a  rock  was  in  front  of  a  ship,  or,  like  Galileo,  you  could  see  the   stars  and  the  planets.  We  went  to  the  moon  because  we  saw  it  in   Galileo’s  telescope  and  got  curious.  He  changed  the  world.  
  8. 8. The  Telescope  
  9. 9. The  Thermometer  ! People  needed  a  way  to  tell  the  temperature  outside  or  inside,   and  Galileo  was  the  man  for  the  job.  ! Galileo  was  taking  medical  school  at  the  University  of  Pisa.  His   first  invention  was  the  thermometer.  ! People  wanted  to  know  how  cold  or  hot  it  was,  so  the   thermometer  was  created.  It  changed  the  world  because  you  may   not  know  if  it’s  cold  enough  for  a  jacket,  and  then  you  get  sick,   and  you  could  die  in  the  old  days,  so  one  of  Galileo’s  discoveries   once  again  saved  people’s  lives,  and  an  important  person,  such  as   Columbus,  could  have  get  sick  and  die  and  we  would  still  think  the   world  was  flat.  
  10. 10. The  Thermometer  
  11. 11. The  Pendulum  ! Doctors  needed  a  better  way  to  tell  for  a  person’s  pulse.   Clocks  were  to  unreliable  and  incorrect.  ! Galileo  saw  a  regularly  swinging  lamp  at  the  church  one   Sunday.  He  measured  the  swings  with  his  pulse.  He  began   Pendulum  experimenting.  !   Clockmakers  could  make  accurate  clocks  so  people  would   know  when  something  started  or  ended  or  how  long   something  took.  Doctors  made  a  device  called  a  pulsilogia,   which  measures  a  patient’s  pulse.  Once  again,  one  of   Galileo’s  discoveries  saved  people’s  lives.
