Study The Mole

Common European Mole

       The  Common  Mole  (Talpa  europcea)  belongs  to  the  order  of  the  Insectivora,  an  order  of  animals  small  in  size,  and  m  stly  of  more  or  less  purely nocturnal  habits.  Closely  akin  to  it  are  the  hedgehogs  and  shrews,  which belong  to  th.  same  order.  The  insectivora  are  in  many  ways  closely  related to  the  bats.  In  general  appearance  some  of  the  members  of  the  order  closely resemble  the  gnawing  animals  or  rodents.  Shrews  in  particular  are  very  like mice,  and  are  usually,  indeed,  spoken  of  as  shrew-mice.  It  was  its  close resemblance  to  the  shrew  that  led  people  in  England  in  olden  times  to  call  the bat  a  flitter-mouse,  a  name  by  which  it  is  still  spoken  of  in  some  parts  of  the country.

       The  mole  is  clearly  distinguished  from  other  insectivores  by  the  perfect adaptation  of  its  form  to  a  subterranean  life.  It  inhabits  the  northern  hemisphere  both  in  the  old  and  in  the  new  world,  not  a  single  species  of  mole being  found  south  of  the  equator.  Its  dwelling  or  fortress  is  usually  formed under  a  hillock,  and  in  its  construction  the  mole  displays  considerable ingenuity  and  engineering  skill.

       Moles  are  exceedingly  voracious  animals,  and  though  living  chiefly  on  worms and  grubs, will,  if  they  get  the  opportunity,  kill  and  devour  mice,  small  birds, lizards,  and  frogs.  The  mole,  in  such  cases,  hurls  itself  on  its  victim  as  if frenzied  with  rage,  and  grasps  it  with  the  ferocity  and  tenacity  of  a  bull-dog. The  mole  is  also  a  very  thirsty  creature,  and  usually  makes  a  run  to  the nearest  ditch  or  pond,  or  supplies  itself  with  water  by  sinking  a perpendicular shaft.

       The  mole,  though  he  sometimes  condescends  to  make  use  of  a  common passage,  is  far  from  being  a  sociable  animal,  and  has  always  his  own  nest  or fortress,  where  in  the  spring  he  brings  his  bride.  He  seems,  however,  to  be possessed  of  strong  family  affection.  Most commonly  in  April  the  young appear.  They  number  usually  four  or  five,  and  are  most assiduously attended  to  by  their  parents,  who  see  to  it  that  the  nest  is  softly  lined  with grass  and  fine  roots.

• The Mole and The Earthworm by Filmbilder & Friends

Method of Student Observation:

• Elicit  that  the  form  of  the mole's  body  is  peculiarly  adapted  to a  subterranean  existence  ;  elicit  also the  use  of  the  short,  thick  fur  in keeping  out  particles  of  earth.
• Compare  the  limbs  of  the  mole with  our  own  ;  also  with  those  of  the bat.  Why  are  the  fore -limbs  so much  stronger  than  the  hind  ones ?
• Elicit  the  adaptation  of  the pointed  snout ;  the  reason  why  the eyes  and  ears  should  be  so  closely protected  by  fur  ;  and  the  advantage of  the  absence  of  external  appendages to  the  ears.
• Compare  the  teeth  with  those  of other  well-known  animals.
• Show  a  diagram  of  the  mole's nest,  with  its  radiating  system  of tunnels.Elicit  the  various  points  in which  the  mole  is  adapted  to  its  habit  of  burrowing,  and  especially the  reason  why  the  palm  of  the  hand is  directed  backwards.
• Compare  the  habits  of  the  mole with  those  of  the  bat,  especially  with regard  to  their  food  and  their  natural aversion  to  light.
• Note  that  the  mole  devours  the farmer's  enemies ‚ worms  and  grubs, but  that  it  also  disfigures  the  land by  casting  up  its  ''hills.''
• Note  that  the  position  of  the mole  in  the  animal  scale  is  very  near that  of  the  bat.  Both  are  mammals exhibiting  a  considerable  degree  of development.
  

How to Grade Study Notes For Student Journals: Every student will need a journal to write in weekly for this online nature study series. Teacher will assign the weekly content in advance.

• Make sure the facts are: written in complete sentences, the first word of each sentence capitalized, and a period should be included at the end of each sentence.
• Spell check your vocabulary and write the words correctly.
• Dress up your journal entries with student clip art, drawings of your own in color or in black and white.
• Student may also include photographs of their own taking for extra credit.

Look for the following facts about moles inside of student journals. Assign a point value to the quality of the content.

• Body. - Long  and  narrow ‚ cylindrical  in  form.  Covered  with  a very  closely-set,  velvety fur.  Terminates  in  a  short  tail.
• Limbs. - Four in number.  Short, strong,  and  terminating  in  distinct toes  with  strong  claws.  Fore-limbs especially  strong,  with  the  palm  of the  hand  directed  backwards.
• Head. - Provided  with  a  long, tapering  snout.
• Eyes  closely  surrounded  by  the thickly-set  fur.
• Ears  without  external  appendages, and  closely  covered  with  fur.
• Teeth  pointed.  No  broad  masticating  teeth.
• Home. - The  home  of  the  mole is  the  soil,  where  it  burrows  its  way in  search  of  food.  It  constructs  a couple  of  circular  galleries  round  a central  chamber,  and  from  these  it makes  a  series  of  burrows  or  runs  in all  directions.
• Burrowing. - The  work  of  burrowing  is  performed  mainly  by  the strong  forepaws,  the  soil  being shovelled  backwards  as  the  work proceeds.  The  sharp  snout  assists the  creature  in  pushing  its  way through  the  soil.  The  soil  is  thrown to  the  surface  at  intervals,  forming little  heaps  called  mole-hills.
• Food.  - The  food  consists  of worms  and  grubs.  These  are  caught by  means  of  the  pointed  teeth,  and generally  swallowed  whole.
• When  the  soil  is  dry,  and  the worms  burrow  deeply,  the  mole  also burrows  deeper ;  but  the  excavations of  the  mole  are  generally  very  near the  surface.
• Young. - The  young  of  the  mole are  produced  alive,  and  are  nourished by  the  milk  of  the  mother.  Hence, like  the  bat,  the  mole  is  classed among  the  mammals.

The Mole Anchor Chart and Classroom Discussion: Direct discussions, develop vocabulary and demonstrate correct sentence writing. Anchor charts are used in many different grades the following example below may be used in 2nd through 4th grade during a group discussion.

1. The  mole  has  a  pointed  snout.
2. Its  body  is  covered  with  soft  fur.
3. The  soft  fur  hides  its  small  eyes.
4. The  mole  has  a  pointed  snout  and  its  body  is  covered  with soft  fur  which  hides  its  small  eyes.
5. The  mole's  legs  are  very  short. The  fore-feet  of  the  mole  are  like  little  hands.
6. Its  claws  are  like  fingers  with  long  nails.
7. The  fore-feet  of  the  mole  are  like  little  hands  and  its  claws are  like  fingers  with  long  nails.
8. The  mole  can  burrow  or  scratch  its  way  under  the  ground.
9. It  finds  worms  for  food.
10. The  mole  can  burrow  or  scratch  its  way  under  the  ground, where  it  finds  worms  for  food.
11. The  long  narrow  body  and  the  pointed  snout,  as  well  as  the strong  claws,  help  the  mole  to  burrow  under  the  ground, where  it  can  catch  worms.

A Paper Mole in The Hole Craft: To make this project you will need: 1 paper plate, a 1/4 cup of rice, green construction paper, parts of a recycled paper egg carton, white school glue, acrylic paints (brown, grey, pink flesh), one cotton ball, one chenille stem and scrap paper.

Step-by-Step Directions:

1. Cut a nose shape from a recycled egg carton and glue this to the center of a paper plate.
2. Then puddle white school glue around this cardboard ''nose'' and sprinkle rice in the glue. Let this dry overnight.
3. Shred multiple shades of green and yellow paper to paste around the rice. Let dry.
4. Paint the rice with brown acrylics and paint the nose piece with grey acrylic.
5. Shred the cotton ball and glue it to the tip of the mole's nose. After it drys paint it pink.
6. Cut pink paws from paper and glue these into the dirt (rice).
7. Cut a chenille stem in half, twist shredded cotton about it with white glue in order to give it a smooth wormy surface. paint is pink and poke a hole under the mole's nose for a mouth to insert the worm inside of.

Left, the beginnings of our mole collage. The nose glued in place, the rice glued down,
 surrounding the mole's nose and the grass clippings added around the brim of
the plate. Right, the rice is painted brown to resemble dirt.
