Lesson Plan
Assumptions:
The students should know what Lysol, Gumby and a black hole are. The students should
not have any prior knowledge of the components of an animal cell or what a cell looks like.
Anticipatory Set:
Getting Attention Focused:
Have students give examples of organs in their bodies that they need to live. Explain
to the students that there are many different organelles in a cell that are needed to
carry out its functions.
Tapping Prior Knowledge:
Give the students a spelling list of the 12 components of a cell. Using scaffolding, the
teacher will draw relationships between the components of a cell, and practical
thinking/memorization skills.
Materials:
Paper, pencils, coloring materials, overhead projector, 3 slightly different diagrams of a cell.
Age:
Ninth grade Science Class
Objectives:
Given 15 minutes and a diagram of a cell with a word bank TLW
a) Label 12 of 12 cell components correctly
(Nucleus, Nucleolus, Cytoplasm, Cell Membrane, Ribosome, Rough Endoplasmic
Reticulum, Smooth Endoplasmic Reticulum, Golgi apparatus, Mitochondrion,
Vacuole, Lysosome, and Centriole)
Teacher Activities:
Modeling/Demonstrating:
Start with the 4 major components of the cell, and then for the remaining 8 organelles,
explanations are arranged in groups of fours according to the similarities between the
organelles. The most similar organelles are grouped together so that differentiations
can be made to avoid confusion later on.
a1) Start by showing the placements of the 4 major organelles in the cell. These are:
cytoplasm (liquid wrapping around the organelles “as far as the sight can C”),
cellular membrane (the container that keeps all the cytoplasm from escaping, like
a jail cell/ “insane in the membrane”), the Nucleus (the large “nut”), and the
nucleolus (“the little O’ nut inside the big one”).
a2) Continuing in groups of four, name the remaining 8 organelles. The second set
consists of the Ribosomes (“Where is my home?”), Rough Endoplasmic

Reticulum/Rough ER (has ribosomes attached to it, making for a “rough ER
hallway”), Smooth Endoplasmic reticulum/ Smooth ER (ER hallway without
ribosome attached), and the Golgi Body (Looks like Gumby’s Body folded onto of
itself).
3) The last set of terms includes Mitochondrion (the mighty cool organelle), the
Vacuole (the black hole), the Lysosome (Lysol), and the Centriole (near the center
and yellow, like the sun).
Guided Practice:
a1) Point to the organelles on the cell diagram and have students name them with the
prior knowledge hints mentioned, and in the order presented. A3) Using the same
diagram, point to organelles out of order, and with fewer or no hints.
Independent Practice:
a1) Students work for 5 minutes in a group of 3-4 on a cell diagram that has a slightly
different layout than the diagram used by the teacher on the overhead.
a2) After the students have turned in their cell diagram (but kept their word banks) have
the students draw their own cell (labeling the parts).
Closure:
“Without looking at your word bank, what are the 12 components of a cell that we learned
today? I’ll point and you name them”. How are you going to remember ‘ribosomes’? How
are you going to remember ‘cellular membrane’? How are you going to remember the ‘Golgi
body’? How are you going to remember the difference between rough and smooth ER?
Evaluation:
Written test (see attached).
TEKS:
(4) Science concepts. The student knows that cells are the basic structures of all living things
and have specialized parts that perform specific functions, and that viruses are different from
cells and have different properties and functions. The student is expected to:
(A) identify the parts of prokaryotic and eukaryotic cells;
