• Chapter 3 and 4 The Atom

2
Rules of the Game

• Each group gets its own question.
• When the question is read, each group gets about
  15 seconds to discuss with group members.
• No notes or textbooks allowed during the
  activity!
• After Mrs. E calls time, all discussion must
  cease and Mrs. E will choose the student to give
  the response. Only that student may speak. If
  any other person in the group calls out the
  answer, the team will lose the point.
• If the group misses the question, the question
  goes to the next group. No discussion will be
  allowed in the next group. Mrs. E will select a
  member of the next group to give the answer.

3
Rules of the Game

• Initial questions rotate from group to group. If
  Group 1 gets a question wrong and Group 2 gets it
  right, then Group 2 still gets their own question
  in addition to the points from the missed
  question.
• Listen attentively to correct answers and as
  questions are explained! Talking during
  explanations or while another team is answering
  results in a 1-point deduction.
• Arguing with the referee (Mrs. E) will result in
  a 1-point deduction from your groups total.
• Regular Jeopardy 1 points each
• Bonus questions 3 point total

Grading

• All students who participate fully in this
  activity and contribute positively to their teams
  earn a 10 point out of 10 point lab grade.
• 1st place team earns 13 out of 10 points on this
  lab grade.
• 2nd place team earns 12 out of 10 points on this
  lab grade.
• 3rd place team earns 11 out of 10 points
