5. Have the “cell membrane people” cut the large piece of plastic wrap in half and place each
piece on the table.
6. Have the “cytoplasm people” form 2 balls using the plain play-doh or clay. Lay 1 ball on
each piece of plastic wrap and press each into a “pancake” about 6″.
7. Instruct them to designate one pancake, “animal cell” and the other “plant cell”.
8. Have members of each group find the supplies they need to represent their cell structures,
cut, form, fold, paste, etc. until their structure is simulated. Then place the finished
structures in a pile on the center of the appropriate pancake. (Exception — cell wall)
9. When all of the cell parts are completed and in place, have someone in each group “gather
up” the pancake carefully cupping it around its “topping” and seal all of the edges together
forming a ball. Next have the “cell membrane people” wrap the plastic wrap around the
cytoplasm and have the “cell wall people” wrap the aluminum foil around the plant cell.
10. Depending on the length of time available, cells may be set aside for the next class period
or each may be cut in half with a large knife right away.
