Presentation transcript:

A Story… You and your Chem class go on vacation to Hawaii. Unfortunately, the boat hits a rock and sinks. You escape to a deserted island. Some people are hurt and bleeding. Two hours later, two crates wash ashore and break on the beach, spilling all over the sand Sugar Chemistry lab equipment Smirnoff How will you survive until rescue comes?

You have to make a drug No problem!!!

Gravity Separation This method works on DENSITY Density = mass/volume High density materials will sink faster

Gravity Separation Lowest density Highest density
