Chemical Caper
Objective To identify the maximum number of substances (elements and compounds) and show an understanding of the periodic table. Cash will be earned with all correct answers. The team which has earned the most cash at the end of the game will win.
Participants Teams of up to six.
Materials Game sheets, game money, periodic table, question sheet, pencils and paper are supplied. Each team may bring a non-programmable calculator if desired, but no other help is allowed (including coaches).

All cell phones must be put away to prevent disqualification.
Rules

Teams must pick up an envelope from the Clue Table. The envelope should contain all materials listed above the game sheet and $300.00 of game money.  
Do not open the envelope until you are at your team table and are instructed to do so.

Part A -- Identifying the Element or Compound   

1. Each team will send ONE team member to the CLUE table to purchase an unknown substance by randomly pulling a numbered disk from the bag to identify which substance they must identified. Only ONE team member may be in line at a time, all other team members must remain at the team table.
The substance will cost between $10.00 and $25.00 of game money.

2. The team member must then re-enter the line to Purchase a CLUE. No purchase can be made without showing the CLUE disk first.

3. A team member may then purchase one CLUE at a time. Each CLUE will cost between $10.00 and $50.00 each. Each clue will be given verbally to the player. It will be communicated to the team verbally as well since nothing can be recorded at the CLUE table. At the team table, members can use the master sheet for recording the clues and listing the substances.

4. Once teams have identified their substance, they may send ONE team member to propose the identity for the substance. Each guess will cost $25.00.

5. If the substance has been correctly identified the team will earn the sum of $300.00.

6. If the substance has been incorrectly identified the $25.00 is lost and the team member must return to the line to purchase more clues or submit another proposed identities at and additional $25.00 or the team member can return to the team table to re-evaluate.
At any time, teams can abandon that particular substance and purchase a new one.

7. The game will last for 30 minutes and will conclude with the transaction in progress at the end of 30 minutes. ALL SUPPLIES MUST be returned in the envelope to avoid disqualification.

NOTE:
1. Calculators are allowed.
2. The quantitative clues are often approximate only, and may have up to ± 10% error. (This reflects the reality of measurement errors in experimental work due to equipment, impurity of samples, technique etc.)

Part B – Showing understanding of the periodic table.

1. Each team will find a periodic table and question sheet in their team envelope. No outside materials may be used.

2. Teams can complete the questions to be awarded a cash value for each correct answer.         

3. Questions will vary, however they will be based on information obtained from the periodic table at the grade 9 level.
Here are some example:

  • Draw the Bohr-Rutherford diagram for Hydrogen.
  • How many atoms in a carbon dioxide molecule? (C2O)
  • What elements make up a carbon dioxide molecule?
  • Which family is Hydrogen?
4. The completed question sheet should be placed back in the team envelope at the end of the game.
Judging

Part A
The total amount of money the team has at the end of the game.

Part B
Each correct answer is awarded a cash value.

Final Score = Part A plus Part B

Student Information Sheet of Physical Properties
1 Cost of substances and clues will be given at the time of purchase.
2 Quantitative values are ± 10% to reflect measurement errors and technical limitations of equipment normally associated with grade 9 quality apparatus.
3 Substances may be either elements or compounds.
4 A wild card clue may give physical, chemical or other information
5 Generally, the better clues cost more; however some quantitative clues may have No Data Available and are given as "NDA".
6 Substances will be chosen randomly.
