1. 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?

2. You have to make a drug
No problem!!!

3. You have to make a drug

4. Drug + garbage + garbage + garbage + garbage + garbage + garbage
A + B  C
What really happens:
A + B  C and D and E…
Drug + garbage + garbage + garbage + garbage + garbage + garbage
20% Drug
80% Garbage

28. Gravity Separation 2 children of the SAME SIZE (same volume)
Kyle: 200 lbs
Tim: 100 lbs
Who will fall first?

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

30. Gravity Separation
Lowest density
Highest density

31. Gravity Separation C A B
Three substances in a centrifuge tube are subjected to gravity separation.
Substance A (1.4 g/cm3)
Substance B (3.0 g/cm3)
Substance C (0.2 g/cm3)
Label the result C A B
