Creating the Frog Scienstructable

What You Do: Want to get a hands-onfeel for the frog? Let’s construct a three-dimensional frog. This is called a“scienstructable”… a constructable,instructable, tangible science model!

First, complete your table on yourworksheet, identifying the 38 organs ofthe frog we’ll 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

13 Stomach Green

14 Small Intestine 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

30 Ovary (female) Yellow

31 Eggs (female) Black & White

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 frog’s 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

It’s a Frog Eat Frog World…Creating the Frog Scienstructable

What You’ll need to create yourscienstructable:

Scienstructable frog template

Scissors

Colored pencils

Small amount of glue or a glue stick

What You Do:

Now it’s time to color your frog!Color the organs according to your key.

You can color the outside of the frog’s body

VARIOUS SHADES OF GREEN, YELLOW,

BROWN AND


It’s a Frog Eat Frog World…Assembling the Frog

Scienstructable

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


It’s a Frog Eat Frog World…Assembling the Frog

Scienstructable

What You Do:

Paste the back of the head on the BACKSIDE of your frog’s 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.


Here’s what is should look like when you’re all done!

Now you have a great tool to help you prepare for your frog exploration.
