STUDENTS THEMSELVES
MODEL THE PARTS AND FUNCTIONS OF THE CELL
OUTSIDE ON THE PLAYGROUND
Model Structure and Function
of Cell Parts
3
students represent the nucleus. They talk
and think together in the center of the
cell.
 Each mitochondrion is represented by an
individual student who is dancing or
wiggling. One, two, or three students can
be mitochondria.
OUTSIDE ON THE PLAYGROUND
Model Structure and Function
of Cell Parts
3
students represent a vacuole. They
stand in a circle, making lots of room
inside the circle
 All of the remaining students represent the
cell membrane. They stand surrounding
the other cell parts. They stand near
enough to touch hands, but far enough
apart to let a person go in between any 2
students when they have their hands at
their sides.

What is the function of the nucleus?
What is the function of the vacuole?
What is the function of the mitochondria?
Demonstrate how the cell membrane can
keep things out (students hold hands or touch
fingers to put up a barrier)
Demonstrate how the cell membrane can let
things in (students drop hands)

 Label
a piece of paper with your name,

 On the paper, write answers to the four
questions on the next slide…
OUTSIDE ON THE PLAYGROUND
Questions!
1.
What is a cell membrane?
2.
What is a cell nucleus?
3.
Which cell part produces energy?
4.
Does a cell membrane let things in or
keep them out?
OUTSIDE ON THE PLAYGROUND
SEMIPERMEABLE
 SEMI:
somewhat, not fully
 PERMEATE: seep into, flow into
 The
CELL MEMBRANE is a semipermeable
wall that contains the cell.
 (has holes in it that can close)
OUTSIDE ON THE PLAYGROUND
Questions!

What is a cell membrane? Surrounds the cell,
lets things in and keeps other things out of the
cell

What is a cell nucleus? It’s in the middle of the
cell, it has the instructions for the cell, “the
brains”

Which cell part produces energy?
mitochondria

Does a cell membrane let things in or keep
them out? BOTH
