Sooner or later a science teacher will require you or your child to make some type of a visual model for a science project. An object that is relatively easy to create a model of is a cell. Whether the focus is on human, animal or plant cells, these models can be relatively easy to create and impress both teacher and classmates.

    Decide on the type of cell you want to create with your Styrofoam ball, such as a particular cell you are studying in class. Have picture of the cell you are going to re-create that displays both the inside and outside of the cell.

    Gather all the necessary materials to make yous cell model. You will want two medium-sized Styrofoam balls, spray paint that matches the color of your cell picture and permanent markers. You will also need toothpicks, name tags, a pen and a knife. The paint, markers and Styrofoam balls can be purchased at a craft store.

    Create the outside of the cell. Cover both Styrofoam balls with spray paint. It is a good idea to do this outside so you don't inhale the fumes. Set the painted balls aside to dry on newspaper or a paper plate.

    Cut one of your Styrofoam balls, once it is dry, in half with the knife. Referring to your cell picture, use different-colored permanent markers to draw the inside parts of the cell with colors that match the picture. The second Styrofoam ball will be used to represent the outside of the cell.

    Use a pen to create labels to identify the different parts of your cell. Label items such as the cell membrane and the nucleus, as well of the other parts of the cell you created. Write the name on a name tag and fold the tag over the top portion of the toothpick.

    Insert the toothpick labels into your Styrofoam cell to identify the different cell parts.
