    Creating the Frog Scienstructable

    What You Do: Want to get a hands-onfeel for the frog? Lets construct a three-dimensional frog. This is called ascienstructable a constructable,instructable, tangible science model!

    First, complete your table on yourworksheet, identifying the 38 organs ofthe frog well be exploring, and thecolors we will use to create ourscienstructable. Use the information onthe following slides to fill in your chart.

  • Number Organ Color

    1 External Nares Black

    2 Internal Nares Black

    3 Tympanum/Tympanic Membrane Light Green

    4 Eustachian Tubes Black

    5 Vomerine Teeth Light Blue

    6 Maxillary Teeth Light Blue

    7 Mandible Light Blue

    8 Tongue Pink

    9 Glottis Purple

    10 Nictitating Membrane Light Green

    11 Retractor bulbi muscle Red

    12 Esophagus Green

    15 Rectum Green

    16 Cloaca Green

    17 Pancreas Yellow

    18 Spleen Yellow

    19 Liver Brown

    On your paper, read the name

    of the organ and color the

    corresponding box the color

    indicated. These will be the colors you will color each organ on your

    frog scienstructable.

    Here are the first 19

  • Number Organ Color

    20 Gall Bladder Green

    21 Kidneys Brown

    22 Bladder Yellow

    23 Lungs Purple

    24 Heart (24L, 24R, and 24V) Red

    25 Common Femoral Artery Red

    26 Common Femoral Vein Blue

    27 Sartorius Red

    28 Gracilis major Red

    29 Teste (male) Yellow

    32 Fat Bodies Orange

    33 Nuptial Pad (males only) Light Green

    34 Spine Gray

    35 Brain Gray

    36 Rectus abdominus Red

    37 Pectoralis Red

    38 Obliquus externus Red

    Here are the remaining 19 organs. Be sure to color the box with

    the appropriate color!

  • Number Organ Function

    1 External Nares External nostrils used for breathing when mouth is closed

    2 Internal Nares Internal nostrils used for breathing when mouth is closed

    3 Tympanic Membrane External eardrum used to sense vibrations for hearing

    4 Eustachian Tubes Opening to tympanum, equalizes pressure in inner ear

    5 Vomerine Teeth Cone teeth used to grasp prey

    6 Maxillary Teeth Cone teeth located on upper jaw, helps to grasp prey

    7 Mandible Lower jaw, helps to grasp prey

    8 Tongue Muscle used to grasp food

    9 Glottis Slit in base of mouth leading to the trachea

    10 Nictitating Membrane 3rd eyelid - covers eye for protection during swimming & eating

    11 Retractor bulbi muscle Used to help push food into esophagus

    12 Esophagus Tube that carries food from mouth to stomach

    13 Stomach Breaks down and stores food

    14 Small Intestine Responsible for most chemical digestion

    15 Rectum Stores solid waste until excreted from body

    16 Cloaca Common exit for feces, urine, sperm and egg

    17 Pancreas Makes insulin to aid in digestion

    18 Spleen Stores and filters red blood cells

    19 Liver Makes bile to aid in the digestion of fat

  • Number Organ Function

    20 Gall Bladder Stores bile made by the liver

    21 Kidneys Filters blood of waste

    22 Bladder Stores urine

    23 Lungs Works in the exchange of oxygen and carbon dioxide

    24 Heart Left and Right atria (receive blood) & Ventricle (pumps blood)

    25 Common Femoral Artery Carries oxygenated blood from heart to lower part of leg

    26 Common Femoral Vein Carries deoxygenated blood from lower part of leg to heart

    27 Sartorius Used in jumping and movement

    28 Gracilis major Used in jumping and movement

    29 Teste (male) Responsible for making sperm

    30 Ovary (female) Responsible for making eggs

    31 Eggs (female) Reproductive cell

    32 Fat Bodies Food reserve for hibernation/mating

    33 Nuptial Pad (males only) Used for grasping female during amplexus

    34 Spine Vertebrae support frog skeletal system, protect spinal cord

    35 Brain Responsible for controlling frogs activities and body functions

    36 Rectus abdominus Muscles that aid in movement

    37 Pectoralis Muscles that aid in movement

    38 Obliquus externus Muscles that aid in movement

    What Youll need to create yourscienstructable:

    Scienstructable frog template


    Colored pencils

    Small amount of glue or a glue stick

    What You Do:

    Now its time to color your frog!Color the organs according to your key.

    You can color the outside of the frogs body

  • Its a Frog Eat Frog WorldAssembling the Frog


    What You Do:CAREFULLY cut out your frog andorgans - no jagged edges! DO NOT cutoff the tabs as you will use these toassemble your frog

  • Its a Frog Eat Frog WorldAssembling the Frog


    What You Do:

    Paste the back of the head on the BACKSIDE of your frogs head not over theinternal structures

  • For all organs to be pasted down, you willapply glue to each tab and match up thelettered tabs as follows:

    1. Choose the sex of your frog. If you chooseMALE, paste down the TESTES by tab A1 to Aon the frog body. Find the hand with theNUPTIAL PAD and glue it to the appropriatehand. If FEMALE, paste down theEGGS/OVARIES by tab A1 to A and choose thehand WITHOUT the nuptial pad and paste itto the appropriate hand. Tape/glue thereproductive organs that you did NOT useonto page 62 of your notebook (under theflaps of the Frog Scienstructable key)

  • 2. Attach the KIDNEYS by tab B to Bon the frog body

    3. Attach the DIGESTIVE system by tabC1 to C on the frog body

    4. Attach the BLADDER by tab A2 toA1 on the frog body

    5. Attach the LUNGS by tab D to D onthe frog body

    6. Attach the LIVER by tab C2 to C1 onthe frog body

    7. Attach the HEART by tab E to E onthe frog body.

  • 8. Attach the SARTORIUS and GRACILISMAJOR by tabs F to F on the frog body

    9. Attach the MANDIBLE by tabs G to Gon the frog body

    10. Cut the ABDOMINAL MUSCLES in halfalong the solid black line through thecenter. Place a small amount of gluealong the outside of the legs along thedotted lines. Paste each half down onthe frog, aligning it with the frog body.

    11. Complete the same process ABOVEwith the frog BELLY. Apply paste atthe dotted lines and align over the topof the ABDOMINAL MUSCLES so thatyou can lift the skin to reveal themuscles underneath.
