Welcome to BTN²The
Biological Trivia NetworkRound Two
How to play• Each team needs 5 large (8.5 x 11) sheets to
indicate their choice:– One each marked A, B, C, D, and E
• For each question, raise the sheet corresponding to the choice you believe is correct
• You may change you answer at any time• The point value decreases with time• The teacher will award points to each group
based on when the correct answer was raised
