Special Notes

To Teacher: The students will decide on their own to
implement the plans, along with the specific
procedures for building the model. The students will
then exchange procedures/plans with another group
(two students maximum).
Allow the students have total creativity for choosing
the materials they wish to use.
Evaluation-set microscopes up prior to lab, cover the
specimen names.
Prior learning should be: organelles and parts of the
cell, and differences between plant and animal cells.

Allow 60 minutes for the students to
complete the 3-D models.
Allow 30 minutes for evaluation lab.
Give students the blank Venn-diagram

Discovering the Cell
Engagement
Why is magnification important to science?
(OBJECTIVES)
 Explore and compare the organelles of different cell
types. (Biology Tennessee State Standards 1.0 Cells)
 Make plans and procedures for building models of
two types of cells.
 Build a 3-D model of a typical cell. (1.0 Cells)
 Classify an unknown cell (prokaryotic/eukaryotic)
using a compound microscope. (1.0 Cells)

Exploration



1) Make plans and procedures using any art
materials supplied for a 3-D Model of both the
prokaryotic and eukaryotic cells that another
group can easily follow.
2) Exchange plans with another group.
3) Follow the plans and build both models.
Explanation

What makes human beings get sick?
Prokaryotic Cells

A unicellular
organism that lacks
a nucleus and
membrane-bound
organelles. (p. 72)
Prokaryotic Cells
Eukaryotic Cells

A cell that contains
a nucleus and
membrane-bound
organelles. (p. 72)
Eukaryotic Cells
Size Comparison
Extension or Elaboration

Use the Venn-Diagram to discover how the
prokaryotic and the eukaryotic cells are different and
alike.
Prokaryotic
Same
Eukaryotic
Evaluation



Number your paper 1-10.
Go to the microscopes and decide
whether the slides contain
prokaryotic cells or eukaryotic
cells. Record your answer on your
paper.
5 Point Bonus: For the eukaryotic
cells, list whether they are plant or
animal cell.
