Stage 1 - Desired Results
Goals/Standards:
PA 3.1.12.A.: Assess and apply patterns in science and technology; compare and contrast structure and function
relationships as they relate to patterns.
PA 3.3.12.A.: Explain the relationship between structure and function at all levels of organization; explain and
analyze the relationship between structure and function at the molecular, cellular and organ-system level.
PA 3.7.12.A.: Apply advanced tools, materials and techniques to answer complex questions; demonstrate the safe use of
complex tools and machines within their specifications.
Understandings:
Students will understand . . .
 The cell is a building block of life
 the cell is made of many complex
structures that carry on life processes
 Life processes exhibit patterns in
processing nutrients and wastes
 Life processes require a balance
between nutrients and wastes
Essential Questions:
 What are the main parts of the cell?
 How do the parts of a cell interact?
 How is the structure of an organelle related to its
function?
 How can cells be distinguished through function and
among species?
 How can microscopes be used to effectively learn about
the structure and function of cells?
Students will know . . .
 names, structure and function of
organelles
 chemical processes of respiration and
photosynthesis
 chemical structure of plasma
membrane
 use and care of microscope
 diffusion, osmosis, selectivity
Students will be able to know . . .
 how cells exhibit patterns that helps to classify them
 that organelles exhibit patterns in their structures that
facilitate their function
 how specific biochemical reactions (respiration) sustain
life
 that microscopes and camera technology require subtle
adjustments to effectively capture images
 cells are selective about which materials cross the cell
membrane
Stage 2 – Assessment Evidence
Performance Tasks:
 set-up, clean and employ the use of
microscopes
 identify plant and animal cells under
the microscope
 describe the functions of the organelles
 apply knowledge of organelles to
analogous systems such as “school
structure” (cell analogy project)
 Demonstrate how membranes are
selectively permeable
Other Evidence:
 draw and describe microscopic images (thread, “e”,
cheek & onion cells, crystals)
 draw, label and compare animal and plant cells
 compare drawn cell images with micro-photo images
 diagram differences between prokaryotic and eukaryotic
organisms
 predict movement of starch/iodine across dialysis tubing
 create a summary portfolio with drawn and/or
photographed images that described in detail

Stage 3 - Learning Plan
Leaning Activities: Students will…
1. draw animal and plant cells with correct organelle identification
2. describe the structure of DNA and the process of protein production
3. diagram and compare plant and animal cells
4. use microscope cameras to photograph and label plant and animal cells
5. compare the selective permeability of dialysis tubing
6. design and implement an experiment that demonstrates how an egg cell is selectively permeable
7. measure and calculate sq. mm and micron measurements at different powers
8. document the independent research (egg cell lab) in a formal lab write-up
