PLANT AND ANIMAL CELL MODELS
We constructed models of either a plant or animal cell. We got together in groups of 4 or 5 two days before the activity and planned what we would bring to represent the different organelles of either a plant or animal cell. Some of the models were two dimensional and others were three dimensional. After we completed our cell model we created a legend which identified each part. Here are some pictures of some of the models we created in the two classes.

Making Three Dimensional Plant and Animal Cells
Purpose: The purpose of this activity is to provide students with hands-on activity which will enhance their understanding of the 3-D characteristics of cells while reinforcing knowledge of plant and animal cell structures.
Objectives: 1. Compare and contrast structures of the 3 dimensional aspect of the cell. 2. Identify the various parts of plant and animal cells and 3. Demonstrate and understand the 3 dimensional aspects of cell structure.
Precedure: Within your group, decide what structures you can use to represent the various structures of both plant and animal cells. Some suggestions are provided. Originality is appreciated. Each group is responsible for supplying the materials required. A play - doh recipe follows.
Cell Structures and possible materials:
|#||Cell Structure||Representative Material Chosen|
play - doh
Construct the cell using the materials brought by members of the group. Start by laying the plastic wrap on a smooth surface and placing the play-doh on the wrap - flatten like a pancake and place the other structures. ** If you are constructing a plant cell, you will have to place the cell wall material first.
When this is completed you have a two dimensional structure. Create a legend identifying the materials used. To complete the 3-D effect - carefully "gather up" the pancake cupping it around the inside structures to make a ball. Seal the edges and complete the cell membrane. If possible you could then carefully use a knife and cut the cell almost in half. When you pull apart the two sides you reveal the inside of your cell.
Recipe for Play-doh ( This makes enough for 4-6 cells.
1 C. baking soda 1 C. Corn Starch 4 tsp. Cream of Tarter
1 C. flour 1 3/4 C. water
Stove top method - Mix and cook until the dough leaves the side of the pan. Cool on a plate with wet cloth on top.
To color play-doh use food coloring or tempra paints mixed in before cooking.
