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
tempera paints (red, purple, green, blue), 1 pair disposable
gloves, yarn or
undercooked spaghetti, pepper, plastic-bubble packing,
aluminum foil, plastic
wrap, pencil shavings, scissors, 1 large knife, glue
