Lesson Plan Outline
Topic
Eukaryotic and Prokaryotic Cells:
This lesson will cover the differences between eukaryotic and prokaryotic cells. It
will also cover cell organelles and their function.
Instructional Objective(s)
1. SWBAT understand and compare and contrast the differences between
eukaryotic and prokaryotic cells
2. SWBAT identify cell organelles.
3. SWBAT match the organelles to each one’s specific role and function
within the cell.
Engage
To engage students for this lesson I will use a mystery box. A model of a cell will be
placed into a box. Students will be split into two teams. Each team will have a chance to
ask up to ten, yes or no questions in order to figure out what is in the box. If a team
thinks they know what is in the box before their ten questions is up, they may talk with
each member of the team and decide to make their guess instead of asking a question
when it is their turn next. Each team will take turns asking yes or no questions until they
have reached ten questions each or until the item in the bag has been guessed. I will then
ask students to recall what they learned about cell theory, being sure to relate the concept
of this lesson to the idea that each cell that is created is formed from a pre-existing cell
and that all the organelles inside of the cells play a role in that cell functioning properly.
Explore
Students will be paired up and given a microscope. Each pair will be given two different
prepared slides, one of which will be a prokaryotic cell and another of a eukaryotic cell.
The students will work together to point out and draw different parts of the cell that they
see for each cell. In case the images beneath the microscope are difficult to see, each pair
will also be given a picture of a prokaryotic and eukaryotic cell. Students will be asked
to point out differences between the two images being sure to show what is present in
one, may not be present in the other.
Explain
For approximately ten minutes, partners will need to discuss and write down what they
have found to be different between the two different types of cells. The students will
then be instructed to move to the computer lab to search the internet. Students must add
on to their previous notes about the differences between prokaryotic and eukaryotic cells.
Each pair should be sure to label organelles and a brief description of each organelle's
function.
Extend
The extend portion of the lesson should begin the following class period. We will start
by discussing what students found to be similar and different between eukaryotic and
prokaryotic cells, being sure to point out the differences between plant, animal and fungal
cells. Students will be given cell diagrams to draw the parts of each cell (fungal, animal
and plant) that are unique to each one. As a class we will build a large venn diagram on
the board. One student from each pair will be asked to fill in one thing that that found
similar and one thing they found to be different onto the diagram. Once every student
has written something (even if it's been repeated several times) we will go over the
diagram together. We will be sure to confirm correct ideas and erase and or adjust
others. Next, students will be given the following list of materials:
1.
2.
3.
4.
5.
6.
7.
Large sugar cookie
Icing
Several different types of candy to represent different organelles
Toothpicks
Tape
Scissors
Definitions of organelle function
Students will pair up with their partners from the previous day. Each student will have a
cookie that they will use to build a model of a eukaryotic cell. As a class, we will go
through each individual organelle, matching the correct organelle name to the correct
function (being sure to point out the few parts that are present in a prokaryotic cell). As
we go through each organell the students will need to fill in the blank on their worksheet,
cut that definition out, tape it to a toothpick and stick the toothpick into a piece of candy
that will represent that organelle. The candy may then be stuck to the cookie with icing.
Students will asked what part of the cell is not present on the list of definitions (the cell
wall). They may take the option of drawing a cell wall around their cookie with icing due
to the fact that cell walls are present on eukaryotic cells, but not all.
Evaluate
Students will be given a blank venn diagram and asked to fill it in with the similarities
and differences of prokaryotic and eukaryotic cells. Students must turn in the venn
diagram before exiting class. Students may work with their partner if they so desire.
Plans for Diversity
Students will be working in pairs for the majority of the lesson. I will pick the pairs in
order to have students helping each other based on their readiness level. The information
is presented in several different ways, using the internet, microscope slides, and building
models. This allows students to have the several different opportunities to grasp the
information by having different ways of visualizing and presenting the material.
