Fun Liquids Experiment

In a earlier post, Liquids: Oil and Water Experiment, I showed how oil and water (both liquids) don't mix and will separate into 2 layers. In this activity we will try to make 3 layers of liquids.





Materials

  • recycled plastic bottles
  • water
  • food coloring
  • oil (baby oil or vegetable oil)
  • mystery liquids ???

Directions

  • First review that liquids are a state of matter. They keep their size but not their shape. They take the shape of their container.
  • Review that oil and water will NOT mix because the oil is lighter or less dense than the water.
  • Pour oil and water into a recycled plastic water bottle. 
  • Observe the liquids. (The oil will rise to the top.)
  • Brainstorm with the children other liquids that they could try to use to make a third liquid layer in the recycled bottle..
  • Have the children predict a liquid which they think will not mix with either the oil or water.
  • Have fun experimenting! 
Suggestions for Mystery Liquids: honey, molasses, shampoo, etc.

What liquids do the kids suggest? What have you used?  Please share your mystery liquids. Can you make a 4th layer?

      Thanks for sharing this idea. Will have to try it with the preschoolers next time I get to work with them. I've linked up to your post on my weekly favorites here: http://play2grow.blogspot.com/2011/04/weekly-favorites-for-april-17-2011.html
