Levels of Organizations
Group Roles and Responsibilities
Manager
Manages the group. It’s your job to ensure that everyone is doing
their job, and only their job. You are also responsible for making
sure that everyone participates and understands the concepts. The
only person who is allowed to speak to the teacher is the manager.
Presenter
Presents group answers to the class. If the instructor asks for an oral
or written (on the board) response from the group, it will be
provided by the presenter. NO ONE ELSE is allowed to add or qualify
what the presenter says. If you want to make sure that your
understanding is presented, the time to do it is during group
discussions.
Recorder
Provides the official record for the group. The presenter is the one
who shares the group answers with the class, but the recorder's
answers are the official written record for the group. If the
recorder's answer is wrong, the entire group could suffer.
Librarian/
Technician
Performs all technical operations for the group. The
librarian/technician is the fact-checker and is the only person in the
group who is allowed to have their book out, and then only if
expressly allowed by the activity or the teacher. All calculations will
also be performed by this individual, so he or she is the only one
who will operate a calculator if one is needed, This individual will
also be responsible for getting and returning any supplies needed by
the group.

Model 1: Anatomy and Levels of Organization
An anatomist is a person who studies the structure of a living thing – how all the little things are organized into
bigger things. The smallest living structures are cells, but there are things even smaller than a cell (such as
atoms and molecules). Figure 1 shoes the level of organization used by anatomists. Table 1 names examples of
the levels of organization shown in figure 1.

6. Organs are sometimes shared by two or more systems- for example, your mouth is
considered to be part of both the digestive and the respiratory systems. Without your
book or the Internet, try to name 3 organs that are shared by two or more body system,
and identify those body systems.
