Like art and music and literature, biology is an adventure for the mind and nourishment
for the soul. (Helena Curtis. Biology. 1979)

Course Goals for the Student: This is the second half of a two-semester course in
biology. This semester is designed to introduce students to organismal diversity—how
organisms are both similar (phylogeny) and different in their form and function
(anatomy). Upon completion of this semester, biology majors will be able to formulate
convincing answers to biological questions related to levels of organization (cells, tissue,
organs, organ systems, organism, society), plant and animal architecture, animal
behavior, plant and animal development, biodiversity, and evolution.
Text: Biology Campbell and Reece (6th edition).
Student Performance Outcomes:
1) When given a biological question, students can discuss or write about it from at least
five levels of biological organization (for example: elemental, molecular, cellular, organ,
organ system, organism, societal, population, community, ecosystem).
2) After learning a biological fact (from a text, a science article, a field trip, an
observation or an experiment), students can summarize it verbally in three sentences
using humor, visuals and an analogy or metaphor.
Absences: Students can make up the weekly executive summaries and definitions for
partial credit. Quizzes cannot be made up.
Notes and Audio-Visual Tapes: Permitted and used according to student discretion.

Tuesday-Thursday Lectures: Tuesday lectures will focus on cell, tissue and organ
systems. Thursday lectures will focus on evolution and animal diversity. Homework for
each lecture (T, Th) is as follows:
(1) Executive Summaries: For each lecture, students will turn in a one-page
executive summary of the assigned topic (see example). The summary can be a
personal story (surgery, disease, injury, pets, etc.) or information from the Internet
about the topic-of-the-day. Each executive summary will count as 10 pts for a total of
20 pts earned each week.
(2) Definitions: For each chapter, students will turn in a handwritten list of 20
definitions from the highlighted words. If a chapter had fewer than 20 highlighted
words, then a smaller number on the wordlist is will suffice. Definitions will count as
10 pts for a total of 20 points per week.
(3) Quizzes: Students will complete a short quiz at the end of each lecture that covers
the material for that day. Each quiz will count as 10 pts. Quizzes are designed to help
the student focus on the important points needed to succeed in the exams.

Laboratory: Each biology lab will be set up as a mini-practical with questions that
challenge the student to compare and contrast animal form and function. Activities for
each lab include:
(1) Quizzes: Each week, a short practical quiz will be set up for students. Weekly
quizzes are designed to help students practice for the mid-term and final
practical exams. Quizzes are 10 points each. No makeup on missed quizzes.
(2) Student Report: Students will produce lab reports. Student lab reports will
include taxonomy and drawings of each organism presented in the lab.
Taxonomic categories and body parts will be labeled in the lab for the
student’s convenience. Students can use the manual as a study guide for
quizzes and practical exams.
(3) Practical Exams: The mid-term and final practical exams will consist of 24
stations with three to four questions per station. Students will identify the
phylum, class or order of animal as well as anatomical parts and processes of
development and differentiation.

Ch 49: Sensory and Motor Mechanisms
Title: What was the cause of my hearing loss over time? [Title must be a question.]
Big Idea: I had a fatty tumor growing on my tympanic membrane. After surgery to
remove a tumor and reconstruct my middle ear with metal prosthetics, I hear better now
than ever before. [Big Idea must answer the question in one or two sentences.]
Summary: The middle ear consists of the tympanic cavity and its components: the
tympanic membrane (eardrum), three ossicles and the eustachian tube. The ossicles
consist of the malleus (hammer), the incus (anvil), and the stapes (stirrup). The malleus is
attached to the tympanic membrane. The stapes is attached to the oval window of the
inner ear by a fibrous ligament. The incus joins the malleus and the stapes. The three
bones are associated with two small skeletal muscles that adjust the tension of the
tympanic membrane in order to convey vibrations to the inner ear. The tympanic
membrane is a thin, rigid, semitransparent membrane made of connective tissue
containing fibrous tissue and elastic fibers. The external surface is covered by squamous
cells. The auditory tube (or eustachian tube) is approximately 3.5 cm in length. The onethird of it is bone. The other two-thirds of the tube is elastic and hyaline cartilage. During
swallowing and yawning, the walls separate, allowing air to enter the tympanic cavity.
Because my left ear has a weak eustachian tube, I have negative pressure in the middle
ear. That pressure over many years caused a tumor, made of rapidly growing squamous
cells, to form on my tympanic membrane. If the tumor had grown through my skull bone,
it could have caused stroke-like symptoms or death. I have undergone six surgeries on
this ear to remove the tumor and reconstruct the ear bones with titanium…I now have a
bionic ear! [Summary must expand on the answer to the question.]
