TESC
fall 2003
activity
objectives:
vTeach
and reinforce the structural components of the human digestive system
vIdentify
and explain the various digestive enzymes
vSet
the foundation for nutritional concepts
Each
student will be assigned an anatomical section of the digestive system
and its physiological role in nutrient digestion.
Instructions
for first part of ACTIVITY:
oRead
about each part/section of your assigned digestive anatomy to assist in
your understanding of how this section of the body contributes to the digestive
process.Chapter 3 of text gives
some information, but you might want to access other sources, either online
or in the library.
oResearch
and identify each enzyme/secretion needed for chemical / bacterial and
/or mechanical digestion that takes place in /because of your assigned
section of the digestive system.Please
remember that you will be teaching the specifics of how these enzymes/secretions
work to break down larger molecules to release nutrients to your classmates.You
should also understand, so you can discuss, any absorption that occurs
in the area you are researching.
oSubmit
a typed outline
[on Wednesday October 1st] of the digestive functions of the section you
have been assigned.Be sure to include
any distinct anatomical structures that relate to these functions.Include
a bibliography of the sources you accessed to research this assignment.
Instructions
for second section of activity [Wednesday October 1st]:
oYou
will mold out of playdoh [provided by instructor] a model of your section
of the digestive system.Using the
model and your notes, you will present your findings, please plan on 15
min. for your presentation. Feel free to bring any photographs or other
aids to assist in your teaching.
oEveryone
will be randomly assigned to a small group, in which each anatomical section
of the digestive system will be represented [in order from mouth to anus].
You will share your knowledge with classmates; take care to make sure everyone
has a solid understanding of both the anatomy and how the enzymes/secretions
work.
oAs
each member of the group presents their piece of the system, they will
add onto the structure being made, with the end product a full digestive
system.
