Endoplasmic Reticulm Lysosomes 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. Materials: ^ Play-doh, food coloring or
