So much more than a "hands on" program

MESA journeyed to Tin Mountain Conservation Center once again. It was great to be joined with fellow MOMS colleague, Patti Seaver, who tagged along to get a better handle on what our little world of MESA is all about. 

Once again we were bombarded with so much great information from Dr. Cline and his interns about wildlife and its many adaptations. We spent the first couple of hours going over a Powerpoint and listening to the presenters give an supersized dose of information for our students. Note-taking and asking good questions were mandatory.

 Below is a sample....created by MESA students, not the teachers...and it's incomplete. Amazing what we ask of these kids. 





What I Need to Know:



Keystone species: an important animal in a habitat. an animal that has a huge effect of it’s environment, and if it were to leave, there would be a huge change, and maybe even eradicate an entire species.

Vestigial: (think Appendix) It is a part of evolution! iis a part of the body (usually an organ) that we used to need, but now we find useless



Homologous: the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.


Analogous: Different evolutionary roots, but the same purpose.       


Osmosis: Watering moved one place to another to even out the solution. Ex.like water moves into another place through a semipermeable membrane (that means the water can go through but the salt can’t) that has more salt.


Homeostasis: the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.


Endothermic: warm blooded. (everything else)- mammals  with exceptions.


Ectothermic: Cold blooded (reptiles and amphibians ex. frog, snake, ext.) it depends on their environment if they are warm or cold, not their blood circulation.


Darwin’s Finches: The Finches that Darwin proved evolution with.


Tympanic membrane: Makes it so they can hear underwater as well as above water (on land) .


Anatomy: The parts of the body.


Physiology: How anatomy functions.


Niche: An animal’s Important role in the habitat. -What that animal dose in the habitat.


Adaptation: A change over time that helps an organism to better survive in various habitats. From the start of evolution to the end of it……….Well not the end but to us now!-like we. humans have opposable thumbs and we walk on two feet,In a milion years we might not have our appendix.


Nictitating membrane: A clear eyelid that animals can see through while swimming under water. For example frogs use their nictitating membrane as an tool to use underwater so they can see.


Adaptive radiation (Galapagos finches...Darwin)....many species originate from 1 common ancestor, kind of radiating outward.


Mammal Evolution: What makes a mammal a mammal? they have fur, give birth and produce milk.

Monotreme: egg layers (think: platypus).

Marsupials: partial internal development (think: kangaroos).

Placental: complete internal development (think: humans, dogs).



Odd-toed ungulate ungulates: Many stomachs, short intestines, have 3 or 5 toes or fingers.



Even toed cytes: Have 1 stomach, long intestines, and 2 or 4 toes or fingers and toads have a lot of warts on toads.Some can also carry some really bad diseases.

Such as: horses, rhinos, etc.

Why is this important??? This is a look into how they fit into their environment; how their adaptations make sense for where and how they live. How the creatures we know came to be. This might help us understand the way they a, behave and effect the environment.



Placental:complete inte

rnal development.


Tetropots: Anything with 4 legs or limbs (tetra meaning 4 in Latin)

Marsupials:partial internal development.


Reptiles: -Ex.snake,-the difference between reptiles and amphibians are that reptiles have scales.


Protozoan: Micro organisms within an animal or creature.





Hawaiian adaptive radioactivity:



Adaptive radioactivity:



Adaptive radiation: when many species adapt from one species. EXAMPLE: Darwin’s finches


Toad              vs.       Frog


-bumpy skin              -smooth skin

-large parotid gland  -small parotid gland

-stout                        -slim                  

-walks a lot               - jumps a lot


Carapace: the top of the turtle's shell



Plastron: the underside of of a turtle's shell


Terrestrial


Amphibian types

Anura: Frog
