Which substance has the highest density?

• Oil

• Water

• Syrup

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball

Combination of two or more different kinds of substances that keep their own physical properties and can be easily separated.

• Solution

• Mixture

• Solubility

• Miscibility
