Materials 2 clear plastic water bottles with lids 2 cups of water One-half cup of oil olive, cooking or vegetable oils will all work Liquid dishwashing soap Clock or timer Permanent marker Measuring cup Measuring spoon Food coloring optional Preparation Remove any labels from your water bottles.

Pour one cup of water into each bottle. Allow the bottle to sit on a countertop or flat surface while you observe the water and oil. Does the oil sink to the bottom of the bottle, sit on top of the water or mix with it? Does the oil sink to the bottom, sit on top of the water or mix with it?

Try not to shake the bottle as you add the dish soap. Make sure the bottle caps are screwed on tightly to each bottle. Holding a bottle in each hand, vigorously shake the bottles for 20 seconds. Set the bottles down on a flat surface with plenty of light. Note the time on your clock or set a timer for 10 minutes. Observe the contents of each bottle. Hold them up to a light one at time so you can clearly see what is happening inside the bottle.

Did anything change when you shook the bottles? And, yes. We like doughnuts. Thanks for asking. Amir Apr 29, Apr 29, Hannah Mar 14, Mar 15, That's great, Hannah! Don't forget to cite your sources!

While holding the glass over a sink in case you spill , shake the glass so that the two liquids are thoroughly mixed. Set the glass down and watch what happens. Do oil and water mix? The oil layer is on top of the water because of the difference in density of the two liquids. The density of a substance is the ratio of its mass weight to its volume.

The oil is less dense than the water and so is on top. The next experiment examines the miscibility and density of several liquids. Being careful not get syrup on the side of the glass; pour the syrup into the middle of the glass. After you have added the syrup or honey, tip the glass slightly and pour an equal amount of the dishwashing liquid slowly down the side of the glass. Does the dishwashing liquid float on top of the syrup or sink to the bottom?

Next mix a few drops of food coloring with water in one of the mixing cups.
