Running it under water works for me ;)

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/

Okay..I'd go with the animal cell. Usually easier.\n\nGet something round that you can glue things to. I bought myself a Styrofoam ball and cut it in half. This is your cell membrane.\n\nER - you know those fuzzy things with a wire inside that you can bend in any shape? Those are good.\n\nRibosomes - Just dot in black dots. -shrugs-\n\nCytoplasm - Colour in the inside of the Styrofoam.\n\nNucleus - Cotton ball\n\nGolgi Apparatus - That candy. Forget what it's called. It's like long and thin and got sugar on it. Really sour. Anyway..fold it over a couple of times.\n\nMitochondia - Raisins.\n\nIf you want to use the above for a plant just put green construction paper around the ball, in a square obviously.\n--\n\nAnother way to make a plant or cell is to use a bowl and put jello in it and then stick all the materials inside the jello. If you do it just right, it'll come out AMAZING. Only thing is it melts in the classroom and if you don't do it right, it looks unbelievably bad. If you want to take a risk and have a bunch of time, try this.

One way I remembered was to draw a picture and label the parts of the cell.  I would draw a new picture over and over again until I could do it without looking for help anymore.\n\nThis website is good.  It gives you the information then it tests you on it:  http://teachertech.rice.edu/Participants/dawsonm/cells/partsframw.htm

Boil the water and catch the condensation on a sheet of metal foil and have it run off into a cup. Its pure water!

WATER. It's that simple.

Its fairly simple to make using a readily available liquid. I'll leave you to search the Internet then decide if you want to make it by yourself or get help from friends

Tap water.\nSoap breaks down the surface tension.

here's what you need:\n\n1.18-gauge copper wire (smaller gauge will work too,2. but 18-gauge is stiffer)\n3.Wire clippers\n4.Steel paper clip (Some people find that a 2-inch 5.strip of zinc works better) \n6.Sheet of coarse sandpaper\n7.Lemon\n8.Help from an older friend or an adult\n\n\nhere's what you need to do:\n\n\nHave your older friend or an adult strip 2 inches of insulation off the copper wire. Clip the 2 inches of bare wire with the clippers.\n\nStraighten out the paper clip and cut about 2 inches of the straightened steel wire, or use a 2-inch piece or strip of zinc.\n\nUse sandpaper to smooth any rough spots on the ends of the wire and paper clip or piece of zinc.\n\nSqueeze the lemon gently with your hands. But don't rupture the lemon's skin. Rolling it on a table with a little pressure works great. \n \nPush the pieces of the paper clip and the wire into the lemon so they are as close together as you can get them without touching.\n\nMoisten your tongue with saliva. Touch the tip of your wet tongue to the free ends of the two wires.\n\nYou should be able to feel a slight tingle on the tip of your tongue and taste something metallic.\n\n\n\nwhat you will discover\n\nThe lemon battery is called a voltaic battery, which changes chemical energy into electrical energy.\n\nThe battery is made up of two different metals (the steel paper clip and the copper wire). These are called electrodes, which are the parts of a battery where electric current enters or leaves the battery. The electrodes are placed in a liquid containing an electrolyte, which is a solution that can conduct electricity.\n\nIn a solution of water and an electrolyte, like the acid in the lemon, an excess of electrons collects on one end of the electrodes. At the same time, electrons are lost from the other electrode.\n\nTouching the electrodes to your tongue closes the circuit and allows an small electric current to flow. A single lemon produces about 7/10 of a volt of electricity. If you connected two lemons together, you can power an inexpensive digital watch (uses about 1.5 volts). (Use a length of thin, flexible wire to connect the silver wire of one lemon to the copper wire of the other lemon. Then attach thin wires from the other two wires in the lemons to where a battery's positive and negative poles connect to power the watch.)\n\nThe tingle felt in your tongue and the metallic taste is due to the movement of electrons through the saliva on your tongue.\n\n\n--well, i just searched for it. hope i helped in a way ^_^\n\n-paul

Do the one where you have a bunch of pennies and you test which liquid cleans faster. i used that for my science project and got a 100 on both oral presentation and organization.\nif that doesn't help, i've found an amazing site with a bunch of projects:\nhttp://members.ozemail.com.au/~macinnis/scifun/projects.htm\nThis takes a while to load but it's definitely worth it!\n\n\nAlso, here are some others: \nhttp://www.cdli.ca/sciencefairs/intermed.html\nhttp://othello.mech.northwestern.edu/~peshkin/scifair/chias_ideas.html#level2\n\nHope they help!

Yo man i shall give u a few sites that wil enable u to design the animal cell and then fill in the design with the items u believe will suit.\n\nhttp://www.batesville.k12.in.us/bhs/science/paper_bag_cell_model.htm\n\nhttp://www.batesville.k12.in.us/bhs/science/sponge_cell_model.htm\n\nhttp://www.batesville.k12.in.us/bhs/science/styrofoam_cell_model.htm\n\nhttp://www.cellsalive.com/cells/animcell.htm\n\n\n\n\n\nfurther details: mng_1432@2die4.com

1. you need firstly to have a total density equivalent to that of fresh or salt water(for whatever purposed required)\nthen bouyancy will be stable/maintained \nthis will make a suitable start\n2. forge a shape suitable to make the sub hydrodynamic, this will enable the prototype to glige through the water \n3. have fun!

a bowl of water, a cork magnet tape and a sewing needle.\n\nFill the bowl with water. Take the needle and rub it on the magnet back and fouth for a long period of time 15 min will about do it. After you are down take the sewing needle and take it to the top of the cork. Take the cork and needle combo and place the cork bottom side in the water. \n\nIf you move the bowl the needle will move.

Take two plastic cups.  Perforate both cup bottoms and insert graphite rods.  Invert two glass jars over the cup bottoms so that the ends of the graphite rods are nearly sealed.  Then connect the ends of graphite on the open end of the cups with wires to a 6V battery (check that the batteries are fresh!).    Disconnect wire-battery connection till later.\n\nhen, prepare an electrolyte solution in a PLASTIC tub. Here, there are two options.  One is a solution of NaCl and the other is dilute H2SO4.  I tried NaCl before, but it gives a generally low yield.  Never tried H2SO4.  From what I heard, I recommend you use that- but use DILUTE H2SO4 (careful not to touch any).   Always make sure (either) solution is warm, so that electrolyte will be surely distributed.  \n\nFinally, lower the cups+jars in such a way that the water goes up 2/3 of the way up the jars (the graphite rods should be completely submerged).    Then, reconnect wire-battery and wait... until water levels drop dramatically (takes a long time).  Your anode (negative terminal) jar contains 02. while your cathode (positive terminal) jar contains H2.  Check presence of O2 by putting a smoldering splint into  the (still) inverted jar- it will reignite.  Check presence of H2 by bringing lit splint into the (still) inverted jar- it will go 'pop'.\n\nHope this works for you.

You can check out this site, it explains a step by step technique:\n\nhttp://www.pall.com/biosepra/34696_7290.asp

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.

what do you like to do? a dry cell normally is 1.5volts. if you want to make a 4.5 volt supply, connect the negative of one to the positive of the next and also the third. the positive of the first and the negative of the third will give you 4,5 volts. for higer voltage, increase the number of dry cell.
