Chapter 4 Unit Test Review

SolutionsRules:Lab Table Teams 1-6

Round Robin - One representative from each lab table will come to a buzzer to receive a question on the board

Each correct response results in 1 point

Rules Continued:Incorrect answer: Same question goes to any other person remaining that did not buzz in before - awarded 1 pointNext question will go to another set of lab table representatives

Outside talking amongst lab tables during a round results in deduction of point

Rules Continued:First response - only response (cannot change answer)
