I took a styrofoam ball and cut one quarter of it out using a steak knife. Then I took a sharpie and drew in the different parts of the cell, but ive seen people use pipe cleaner, sponges, and printed out pictures to show the parts. Then I painted the outside area using regular craft paint. Then its just a matter of letting it dry. Thats what I did and it worked, if thats what youre asking for.
Cut the ball in half and try to get some arcylic paints. Cut a small portion of the bottom to make it flat. Then paint the round part of the half circle whatever color you like then once it is covered let it dry and place the flat side down. Then paint the flat side anything you want, while painting the cell I recommend looking at a picture. Sorry if this doesnt work!
You could get half a styrofoam ball and find some stuff that looks like the parts and then glue it on. You can also use clay and stick it on or paint on it. Some items you can use are pasta, paper clips, clay, thumb tacks, string/ribbon, and pieces of plastic, or cardboard. You can make cakes and ice the top to look like the parts of the cell, but you'd have to eat it. Hope this helped.
You can take half a Styrofoam ball, spray paint it, find some stuff around and stick it on, or you can paint it. Some people make little cakes and use icing to create the parts.
Easy carefully mold out the parts of the cell and either stick them on or glue them on.
Add a little paint and some objects from around the house hot glued in place to represent all the parts.
For a science project
I don't know. But, I have to make one for school. And it's due friday. :( I've started mine and it made out of a cereal box. The nucleus is half a bouncy ball.
