					                             CHEMISTRY SCAVENGER HUNT

Remember, this is a team effort (teams no more
than four). Find as many items as you can.
Finding all 50 would be a tremendous feat!!! All
samples should be in an appropriate container
(solids in a ziploc bag and liquids in a plastic
bottle), and each container should have attached
to it a 3 inch by 5 inch index card with the
following information: team members name,
question #, answer to questions asked about the
substance or required calculations. No substance
can be used for more than one item on the
scavenger list. The entire collection should be in
a box decorated to represent your team and
included the name of each member of your team.

ITEMS FOR SCAVENGER HUNT

Scavenger Hunt Grading Criteria: Worth 125 points. Grade will be determined by the % of
items correctly identified and labeled and team effort. To get credit for correctly answering
a problem all calculations must be shown. The Team that finds the most items receives
additional extra credit. Items must be turned in a box decorated to represent the team.
