Chapter 4 Unit Test Review Solutions
Rules: • Lab Table Teams 1-6 • 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 point • Next 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: • Allow me to read the question fully before responding • First response - only response (cannot change answer)
