Step 1 Add Oil to Water.

. Use a cotton bud to move the oil around surface of the water. Keep the card between the containers to let the liquids settle. Slowly and gently remove the playing card. Made in partnership with the National Science Teaching Association.

The oil will float on top of the water. Set the oil in place over the container holding the water. Watch the oil fall and rise. Its just mesmerising to watch how colour patterns formed in this experiment.

Use a salt shaker to pour salt over the mixture. You will notice that the oil will not mix with the colored water. Add cooking oil to almost fill the glass. Since oil is less dense than water it will remain on top of the colored water.

Drop a small amount of oil onto the water. The following easy-to-set-up experiment involves mixing equal parts oil and water and then adding a drop of food coloring. A liquid that has a greater density will sink. Fill a glass about two-thirds full with tap water.

A liquid that is less dense than water will float on the water. Then distribute the materials. We used baby oil here but other oils will also work. Begin the first oil.

Small cups or bowls these are my favorites for drinking art and ice cream Pipettes or syringes like the ones left over from little kid medicine In small cups clear is best put 12 cup or so of oil. You only need three simple ingredients a minute to set it up and you will hav. Now for the really neat part. Although this experiment uses the same volume of oil as water the two liquids have different masses and therefore different densities.

The oil even a little drop will spread out over the water surface and break up into many little blobs. Fill the bowl with water to an inch or two below the rim. Begin by filling a shallow dish with oil. Pour some baby oil into the cups with a dropper.

Mixing Oil with Water Once materials are ready and the new vocabulary terms have been introduced to the students create groups of three or four students. Half fill the clear container with water. Continue adding salt to keep the movement going. This will happen very quickly.

Now watch what happens. Oil I use vegetable oil because its cheap Water. Even if you shake the container cover it first the oil and water will separate again. Density is a measure of how much of a substance is contained in a specific volume of liquid.

Add a couple of drops of food coloring and stir. The water-based drop remains intact until it sinks through the oil and contacts the water at which point the color at last disperses. Ad Science lessons videos for grades K-8. Start by adding a few drops of food color to different cups of water.

Place it on a table and have everyone crowd around it. Next to them put a few cups of water dyed with food coloring. Stir it and observe the color dissolve into the water. In a cup combine 3-5 drops of food coloring with water and mix using one cup for each color of water that you wish to make.

Lift the oil container turn it upside-down and line it up directly over the water-filled container.
