Lesson #2: “Pizza
Parlor Predicament”
Unit: Cell Structure and
Function
Subject: Biology
Grade: 9th
State of
Objectives
1. TSW label the
parts of an animal cell
2. TSW match cell
organelles with their respective functions
Set
The first PowerPoint slide will contain a picture of a pizza
parlor and ask the question, “In what ways are a pizza parlor and a cell
similar?” The structures and functions of a cell will be compared to those of a
pizza parlor throughout the remainder of the presentation.
Instructional Procedures
1. TTW use
PowerPoint to identify the parts of a cell and their associated functions, and
make a comparison between cell structures and functions and those within a
pizza parlor.
2. TTW provide
guided practice, as indicated below.
3. TTW check for
understanding via assignments, as indicated below.
4. TTW return
graded assignments to the students via email, to be used by the students to
study for the upcoming unit test.
Guided Practice
TSW complete
the Eukaryotic Cell Interactive Animation activity found at http://www.cellsalive.com/cells/cell_model.htm.
Checks for Understanding
The following assignments will be completed by the
student and evaluated by the teacher:
1. TSW label the
numbered parts of the cell diagram on the handout posted on the class website.
The answers will be listed in a Microsoft Word document and emailed to the
teacher.
2. TSW compare a
cell to their school and use that analogy to describe the parts of a cell and
their functions. This assignment will be completed using Microsoft Word and
emailed to the teacher.
