Transcript of light ice & heavy water

Light Ice Heavy Water
Baby Oil
Vegetable Oil
Ice Cubes (2)
Food Coloring (optional)
Clear, empty container (drinking glass)
NOW LET'S WATCH
THE DEMO!!!!!!!!!!!!!!!

Period 4

Background Information
Materials
Procedures
1. Put 2-3 drops of food coloring at the bottom of the glass
2. Fill half of the glass up with vegetable oil
3. Fill the rest of the cup with baby oil
4. Carefully place the ice cubes in the glass

Science Behind
the Demo
-Water is more dense than the vegetable oil and baby oil
-Water sinks to the bottom
-Ice is less dense than water, causing it to float.
-Density: Mass/volume
-Anything less dense than water will float
-Anything more dense than water will sink
-Water is less dense when frozen than when it is at liquid state
-polar molecules:
-non-polar molecules: the electrons are distributed more symmetrically and there is no abundance of charges at opposite sides because all charges cancel each other.
- Water and the oils do not mix because water is a polar molecule, and the oils are non-polar.
