Senior Final Exam: Conceptual
"Road Rally" Challenge |
With a total of seven stopping points or puzzles
on this overview, class members must work as teams to solve the riddles
and problems they encounter.
Each clue builds on the last until the final
destination is revealed. Each challenge must be solved before getting the
next "location" of the next puzzle. These puzzles can exist in the analog
or digital realms.
IF all seven challenges are not solved by the
teams, then the final password to get out of the written final exam will
not be gained and the team is obliged to finish solo with paper and pencil
what they could not achieve as a team. |
