Get wooden matchsticks and cut the heads off of them.  Then it is a simple means of making the design and building it.\n\nOr you can order this kit.

try sketchup from google..\n\nhttp://sketchup.google.com/\nhttp://sketchup.google.com/3dwarehouse/\n\n...

The other posters have all given good answers.  Think about scenes you see set up in a museum - they are large scale dioramas - your sister's will be a small scale version.  \n\nYou might want to paint the inside of the shoe box or line it with a fabric that will be a good one for the project title.  My kids used pictures cut out of magazines glued on popsicle sticks if they needed to stand up, plasticene, bits of stick, grass, stones, leaves, miniature figures and furniture, etc. (depending on the topic) from the dollar stores, play dough shapes, aluminum foil to represent rivers sometimes, artificial snow spray, anything that would add to the appearance. \n\nPlanning is important - you might want to have two shoe boxes in case you need to start over.  But overall it is an easy and fun project, and painting the inside of the box with a simple scene goes a long way toward creating a good diorama.\n\nI hope this helps.

I'd try a craft store, or a model/hobby store in your area, or try the links below.

I'd recommend Playdough (or similar clay material) as the basis.  You can make your own "dough" or buy some.  If you use different color Playdough, you can easily distinguish the parts of the cell.  And you can add paper flags glued to toothpicks to label the different parts (or make a color-coded legend).\n\nIf you find items that you want to have represent cell parts (e.g. threads = filaments, marbles = mitocondria, pipe cleaners = centrosome, etc.) you can just stick that into your clay model.  For things you can't find items for, just make them out of different colored clay. But I think clay as the basis for the cell model makes a lot of sense.

If you are making a model this might be useful for you:\nUse cardboard to create a ocean with ups and downs. Cover it with dark blue oil paint and some white color for the foam. You can use transparent plastic sheets to cover this model to get a glossy effect. Try not to put the sheet very tight. Stick it loosly so that it creates an effect like waves.\n\nIf you want to make the whole classroom ocean-like, then make it slightly dark and run a cassette with the sound of the waves.

Look at the Eifel Tower or a local steel bridge. A model airplane shop could help with the wood and look at an airplane body frame. \nTo calculate, look for a statics book. Engineers need to know how much force each piece has to hold.

I did something like that for a science project too. Only mine was a cake with decorations that made it look like a cell... ^_~\nWe also have an actual model of animal and plant cells in my class, but those were mail-ordered. For a really realistic one, you're gonna need some special parts.\nYou can do it more easily with a styrofoam ball of a reasonable size (or a styrofoam cube if you're doing a plant cell), another smaller ball (for the nucleus), I'm not sure what you could use for mitochondria.... Hit a craft store and get creative. There's plenty of stuff out there just waiting for you to find it. Pom-poms could be used for the vacuoles I guess, and you could coat the larger ball with playdoh for the membrane. I'm sure you'll think of something. Remember this when you're working: hot glue guns are your friends.\nJust remember to include all the components:\nNucleus, cytoplasm, vacuoles, mitochondria, cell membrane, endoplasmic reticulum, and the two extra plant parts: chloroplasts and that extra thick wall whose name in English I cannot recall... xD\nIf I can make a sponge cake into an animal cell with some Fuzzy Peaches, Rockets, jelly beans and chocolate sprinkles, I'm sure you can make a styrofoam ball into something just as good or better. Best of luck!

There is a page linked below showing how to make a cell model from a styrofoam ball.

i would say if you aren't wanting to clinb it, use paper mache and balloons to make a wall of "rock".ill i'm bac. mix together glue and water and flour, (i think, look up a paper mache recipe) get news paper (you are gunna need alot) and cut it into 1 inch strips. blow up lots of balloons. (i would say that a good idea would be to put the balloons together with doublesided tape before you begin the next part. make it as big as the wall you want this on.)\ndip the strips of newspaper into the glue mix and begin to layer it onto the balloons. ley dry for 24+ hours. paint as desired.\n\n:D happy "climbing"!

Use clay and then you'll be able to form the 3d shapes

make a catapult or a trebuchet\nmake a lever\nmake a hydraulic lift ( soda bottle hosing balloon housing for balloon like a box or can, something to lift}

Wow, thats a tuff one. Have you considered cardboard or wire and fabric? How much time do you have because this seems like a time consuming task. You could look on the internet fo ideas that might help you out. It depends on what you want it to look like.

Either draw it and scan it or if you are making it on the computer i would say adobe photoshop. If you want to try and animate it then some flash program - maybe fireworks??

If you have to actually build this thing then a castle-style drawbridge would probably be the easiest thing I can think of. \n\nBuild a tower out of boxes, wood or whatever. If you’re real lazy simply stand a shoebox on its end and paint an archway on what was the bottom.\n\nCut a piece of cardboard slightly narrower than the base of the box and about 8 inches long. That piece of cardboard is your span.  Bend the first couple of inches of the cardboard up at right angles. Push thumbtacks through that bent up section and into the tower a few inches above the tabletop. That way when the span is lowered it will slope downwards on to the table.\n\nPass a piece of wire through a cotton spool and bend both ends around to make a U shape. Bend the ends of the “U’ shape into tight circles. You can now put a screw through those circles and into a piece of light wood/heavy card that you can glue to the tower somewhere near the top.\n\nPoke a hole in the free end of the span. Tie some thread through it. Pass the thread around the cotton spool a few times. \n\nYippee, finished in one afternoon.\n\nWhen you turn the spool the span will lift. The spool is both a wheel and a pulley system. The span itself functions as a lever. Because the span slopes downwards onto the table top it is an inclined plane/ramp.\n\nAttaching a couple of parts using screws and a couple more using nails/tacks gives you your screw and wedge.\n\nSimple. Next time don't procrastinate.

Check out the national Geographic stores, they sell alot of these things in kit form that you have to build. Or if you need to use your own materials, find a picture or check a museum of an easy skeleton, make the parts our of either hard setting icing or bread doe and varnish it.
