Each person at your table needs a whiteboard, marker, and rag. You will also need a periodic table and a calculator If you find a dead marker, please THROW IT AWAY (don’t just put it back in the tub…)

Rules of the game For each question, one point will be awarded for a correct answer WITH WORK SHOWN AND CORRECT UNITS. If you are off task (doodling, on your phone, sleeping, etc) your team will lose a point The winning team will be given 1 extra credit point on their test Work together, ask questions, make sure you GET IT.
