1. After studying cell structure, divide
the class into small groups.
2. Gather all materials and have them
laid out according to the number of student groups.(See
material list.)
3. Distribute materials and lists of
cell structures to each group.
4. Inform groups they will be making
plant cells. When they finish, each cell will be about the
size of a baseball. The first part of the class period will
be spent making the cell structures themselves. Instruct
them to wait before putting the cells together until you
can explain the procedure. Have group leaders assign responsibility
for each cell part, to the group members.
5. Have the "cell membrane people"
cut the large piece of plastic wrap i and place the pieces
on the tables.
6. Have the "cytoplasm people"
cut the large piece of wax paper and place the pieces on
the tables.
7. 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 "cytoplasm".
8. When all of the cell parts are completed
and in place, have someone in each group"gather up"
the cytoplasm carefully cupping it around and seal all of
the edges together forming a ball. Next have the "cell
membrane people" wrap the cellophane around the cytoplasm
and place in the "cell wall".
