MAKING THREE DIMENSIONAL PLANT CELLS

Materials:

nucleolus

light bulb

Cytoplasm

cellophane

Chloroplasts

small fuzzy balls

Nucleus

clear plastic ball

Lysosome

red beads

Cell membrane

wax paper

Ribosomes

small fuzzy balls

Endoplasmic reticulum

bent pipe cleaners

Cell wall

brown paper lunch bag

Mitochondria

plastic beads

Microtubules

clear plastic cord

Chromosomes

yarn

     

Vacuole

bubble wrap

     

Procedure:

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".
