Cell Division Review

Around the World- Rules•One person will stand behind the desk of another. • I’ll ask you a question. The first of the two people standing together to say the correct answer coherently wins and will move onto the next person.•After answering 5 Q’s consecutively, person will sit down at his challenger’s desk. The challenger will take his place and the game starts again with the two new challengers. •Winner: • Academic- Make your way around room and back to seat 3 times.•Honors- Make your way around room and back to seat once.
