Abstract
In this activity, students take notes (using the two-column
notetaking format) on the essential cell organelles. The illustrated
notes focus on the structure and function of these organelles. The
notes are presented using a Power Point presentation (attached). The
organelles discussed are: cell membrane, nucleus, cytoplasm,
mitochondria, vacuole, lysosome, endoplasmic reticulum, ribosomes,
cell wall and chloroplast.
Lesson fundamental understandings:
Essential
Questions: ENDURING UNDERSTANDING:
"Structure" is
how something is built. "Function" is how something works. How
something is built affects how it works. Likewise, how something
works affects how it is built. This is true with all living
things.
ESSENTIAL QUESTIONS:
- How would the function of a
cell change if the structure was altered?
- What would happen to
the structure of a cell if it began to function
differently?
KNOWLEDGE AND SKILLS:
The events leading up to
the discovery of cells is worth being familiar with. The components
of the Cell Theory are important to know. The fact that the
structure and function of living things is forever linked is an
enduring understanding.
Standards
National Standards CONTENT STANDARD C:
STRUCTURE AND FUNCTION: Living systems at all levels of organization
demonstrate the complementary nature of structure and function.
Important levels of organization for structure and function include
cells, organs, tissues, organ systems, whole organisms and
ecosystems. Cells carry on the many functions needed to sustain
life. They grow and divide, thereby producing more cells. This
requires that they take in nutrients, which they use to provide
energy for the work that cells do and to make the materials that a
cell or an organism needs.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++ TECHNOLOGY
FOUNDATION STANDARDS FOR STUDENTS -- Social, ethical and human
issues: Students develop positive attitudes toward technology uses
that support lifelong learning, collaboration, personal pursuits and
productivity. Technology productivity tools: Students use technology
tools to enhance learning, increase productivity and promote
creativity. INFORMATION LITERACY STANDARDS: The student who
contributes positively to the learning community and to society is
information literate and participates effectively in groups to
pursue and generate information.
State Standards CONTENT STANDARD 6.0 --
STRUCTURE AND FUNCTION: Students understand that all life forms, at
all levels of an organism, use specialized structures and similar
processes to meet life's needs. 6.5.2 -- STRUCTURE AND FUNCTION:
Investigate, compare and contrast the different structures of
organisms that serve different functions for growth, reproduction
and survival. 6.8.3 -- STRUCTURE AND FUNCTION: Investigate and
describe how cells grow, divide and take in nutrients, which they
use to provide energy for cellular function. 6.8.5 -- STRUCTURE AND
FUNCTION: Investigate and describe how plants have specialized
structures and systems for a variety of functions.
Lesson
Prerequisite Skills
Prior to beginning this lesson, students should be familiar with
the following concepts: - two-column note taking
- components of the Cell Theory
- proper use of spelling and grammar
Teacher
Information/Situations/Setting/Time The students will
work independantly taking notes on the cell organelle's structure
and function.
The teacher will lecture, answer question and
facilitate discussion while running a Power Point presentation on
the topic. At various points during the lesson, the teacher will
show the students information found on several different web
sites.
The notes will be taken over a period of two days.
Assessment
FORMATIVE ASSESSMENT:
Continual observation and questioning
throughout this lesson will provide some means of assessment. After
successfully completing this activity, students are encouraged to
move on to the next activity. The mastery of each activity provides
both the teacher and the student with an opportunity to assess their
current progress. Daily learning logs also allow the teacher to
determine the level of the students' understanding. Though this
activity will be assessed, it will not be given a
grade.
SUMMATIVE ASSESSMENT:
Summative assessment will
occur in the journaling activity, which will be completed at the end
of the unit.
Student Activity/Tasks Students take
notes (using the two-column notetaking format) on the major
organelles located within a cell. The notes are presented on a Power
Point presentation. The notes include illustrations as well as
important information regarding the structure and function of each
organelle.
Enrichment/Alternate Activity:
Special needs students may benefit from completing a worksheet
where they enter a portion of the notes and indicate the organelles
on a previously illustrated model, as opposed to being responsible
for completing the full volume of the notes. Students may benefit
from an introductory activity that has students look at the
structure and function of common items. They can be presented with a
list of objects (spoon, comb, rocking chair, etc.) and determine how
their functions inspired the development of their structure.
Cross-Curricular:
Technology
Requirements/Tools/Materials
Since this activity involves a Power Point presentation, a
computer is an obvious requirement. Teachers also need to determine
how this presentation will be accessed by the students. In a
computer lab, students would be able to advance through the notes at
their own pace. In a whole class environment, teachers would need to
use an LCD projector or a television and the required connecting
cables.
