Oil and Water Do Not Mix!

We've been discussing how some items can mix together like water and food coloring!  Today we are discussing how some things do not mix together!

In a shallow pan put just enough water to fill up the bottom of the pan.  
Put in drops of food coloring  Move the water just a bit to see how the colors combine together to make different colors.

Then add a 1/2 tablespoon of vegetable oil to the pan.  Students will observe the colors moving around and the water and oil with separate and even cause areas of the pan to not have any water of the bottom.

Using a cardstock paper, place it on top of the liquids.  The students loved the effects.
