how to make a science project on the mixtures of oil and water?

if you want to clearly show how they separate you can add food coloring to the water, and it won't mix with the oil.

The oil is usually within a layer of porous material. Imagine a bucket full of marbles and water. You can get the water out of the bucket without disturbing the marbles much at all.

Do you mean the experiment where you measure the size of an oil drop, then place it in a petri dish that has talcum powder or some such on it. The you measure the size of the pool of oil in the petri dish?\n\nIf so, this experiment was to calculate the approximate size of a molecule. \n\nEssentially, by measuring the diameter of the droplet of oil you can work out its volume (πr3). Then the nature of oil on water is to settle until it has reached a molecule's height and then to disperse. So, at its peak you measure the radius of the circle formed in the petri dish and you can work out how big the area is (πr2). \n\nThe volume of the new pool is then \n\ninitial_voume/secondary_area =  molecule height\n\n\nDoes this answer your question?

You could easily (and cheaply?) demonstrate capillary action, the effect that draws ink up the split nib of an old fashioned pen or quill pen.  Suspend various strip samples of material from a rod over a pan filled with water and food coloring and see how far the liquid clims various materials (diferent natural and synthetic cloths of tight and loose weave and paper and wood, etc.  Make at least two samples of each material so that you can experiment at home and then set up the rig at school in the order you found to show the most to the least capillary action and explain why.  Study one or more websites for an explanation of the effect.  Good luck.

some good projects for kids are at-http://pbskids.org/zoom/activities/sci/\nthese might be too easy for anyone older than a 3rd grader, but they're still something!\n my little brother is doing the water filter.  he's going to see which of the materials filters water best. good luck! :)

That's a big no.  The same chemical properties that make it so oil and water don't mix makes it so oil cannot conduct electricity...ever!  In fact, to make it do so you'd have to change it's composition so completely it wouldn't really be oil anymore! :-P

Here's some ideas\n\n(1)\nMeasure the hardness and ion content of your local water supply.  You can perform precipitation experiments, measure solid residue after evaporation, and more.\n\n(2)\nSeparate the protein solids and fat from milk.  I think you can do this by adding salt to the milk.  (I've never done it, may be too easy.)\n\n(3)\nDo a project on the danger of confined spaces.  There is a really cool visual experiment that goes along with this.  If you mix vinegar and baking soda in a tall glass you will get a glass full of carbon dioxide.  Since the carbon dioxide is heavier than air, it will stay in the glass for a while (invisibly so).  You can then make a "pouring action" and pour the CO2 into a second glass, although there is no visible flow of gas.  You also need a 3rd glass that has a small, lit candle at the bottom of the glass.  You then make the same pouring action with the second glass into the third and when the CO2 displaces the oxygen and nitrogen in the third glass the candle will get snuffed out.  You can even do this experiment at home for fun!\n\n(4)\nMeasure the pH of common household materials: foods, cleaners, etc.

1. surface tension of water. See the different surface tension of different liquids in different containers, e.g. test tubes, beakers, glass, etc... Another is look at the surface tension of water at the glass or beaker, would a thread, pin , paper would float? And when a detergent powder was added what would happen?\n2. geology, look around, look around the environment, are the rocks the same? gather as many as possible rocks and differentiate each of them. In other words classify them.\n3. Do an investigatory project about the faces of the moon, draw them.\n4. Give or look for evidences or proofs that the earth is round.

I saw the other day you could mix Mentos and Soda with explosive results.  Jobwise, you could look at food manufacturing plants.  They always need people to test the viscocity of twinkies or the acidity of Coke.

I found a web site with a lab on how to figure out releative density of a given liquid hope it helps.  It has all the instructions and materials needed listed on the site

Given that kerosene and water are not miscible, and have a different density, a centrifuge could separate the two liquids.\nAlso, since water boils at 100 C and freezes at 0 C, while kerosene will boil at more than 150 C and freeze at less than 0 C, then heating of chilling the substance would allow distillation separation, or the creation of a hydrocarbon water slush that could be treated fop separation.\nYour best best is distillation, still.  That is how crude oil (which does contain water) is treated anyway.

if u want to make a good sciences project and u want it easy take a cup and add watter and then grab a piece of cardboard and and cover the glass and then turn the cup upside down and then the water wont fall ok

Vegetable oil and isopropyl alcohol.  Put a little food coloring in to help differentiate between the two (it will only dissolve in the alcohol)

measure water, water temp and motor oil on glass, metal and plastics times 3 (using three different detergents three containers in which to clean them and report on how they each work how long it takes for them to work and the quality of the job.

Below is a website through Yahoo! just for science fair project ideas, etc.  I hope this helps.

Oil is less dense than water.
