The Chemistry Hot Seat

• Break into groups.
• I will provide you with a question.
• Everybody in the group will write down the
  question and provide an answer for the question.
• One person is on the Hot Seat, I will check their
  answer first.

2
Scoring

• Scoring is as follows
• If the person on the Hot Seat answers the
  question correctly, your team will score 6
  points.
• If the person on the Hot Seat answers it
  incorrectly, I will check the remainder of the
  groups answers. You will score a single point for
  every correct answer provided.
• Note Group members are not allowed to share
  their answers.
