YOUR LAB CHOICES
Flashing Lights: Concentration
Determination
• Using color to determine
concentration
• Using a standard curve
you will be able to
calculate the unknown
concentration by
interpolation.
Ice Cream Chemistry
• Colligative properties
• Study of the impact of amount
of solute on boiling point and
freezing point.
• Extra Credit – Research and
implement how colligative
properties are used to make
ice cream.
Battery Chemistry
• Batteries are powered
through
oxidation/reduction
reactions.
• You will be studying
this chemistry in your
lab.
• Recommended for
those going into AP
Master of Titrations
• You will be running
multiple labs that allow for
you to analyze and
determine the
concentration of an acid
and base.
• For those that enjoyed the
first titration lab.
Eat Your Vitamins!
• Vitamins are compounds
that are vital nutrients for
living organisms
• Many companies sell
vitamin supplements
• You will be investigating
whether the advertised
amount aligns with the
actual amount.
Swim with the Fishes
• Seawater contains
many different types of
compounds.
• Roughly 3.5% of the
seawater is various
compounds.
• Analyzing ions found in
seawater from Santa
Monica, CA.
Crazy for Le Chatelier
• Equilibriums have certain
ratios of products and
reactants that needs to be
maintained.
• Keq is the mathematical
value that describes this.
• Recommended for those
taking AP
Direct and Indirect Love of the Gas Laws
• Study of Boyles and
Charles Law
• Does the data show
these direct and
indirect relationships?
• Get to use dry ice!
Double Bubble Toil and the Ideal Gas
Law!
• When acids react,
bubbles of CO2 are
sometimes produced
• If you know certain
conditions then values
of this acid can be
calculated using
PV=nRT
Catching Fire
• Values like Cs and
ΔHfusion are often
given, but we can
experimentally
determine them.
• Running multiple
calorimetry
experiments.
Real Life Walter White: Making Compounds
from Aspirin
• Utilize organic
chemistry to synthesize
methyl salicylate
(wintergreen smell in
food) from aspirin.
• Large amount of
research will be
required
Real Life CSI
• Forensic science
required extensive
amounts of chemistry
• You will be using
chemistry to detect
unseen fingerprints
and for the presence
of arsenic/antimony.

Background Reading
• Read the excerpt and answer the
corresponding questions
• This will be used to inform your procedure
How Do I Make a Procedure?
• Make sure to read the uploaded handouts.
THESE WILL GIVE YOU A STARTING
POINT.
• Be as detailed as possible. No step is too
small to write down.
• Draw pictures if it is going to help you
visualize the lab that you are going to run.
• Don’t forget that you need to control
variables!
Develop a Procedure
• With your partner develop a procedure by
filling in the gaps to the procedure that
was given to you.
• Have Mr. Lance check it when you are
completed.
Closing Time
• AP list will be posted on my door
afterschool today
