EOCT Challenge Rules of the Game 1. At the beginning of each turn, one team member shall roll the dice. 2. The sum of the numbers from dice is the number of points the question will be worth. 3. If the sum of the dice equals 7 then the team member may roll again to add extra points. 4. If the sum of the dice equals 11 then the team member may roll again and add half of the points. 5. Another team member will pick a question card. 6. The team will then have to answer the question correctly 7. If the team gets the points correctly then the question points will be added to the team’s total. 8. The team will be awarded 3 bonus points if they can provide an explanation for their correct answer (Teacher may use his/her discretion) 9. If the question is answered incorrectly the question points will be subtracted to the team’s total. 10. The selected opposing team can gain 3 bonus points if they can correctly answer the question. (Jump Ball Method) 11. The team with the most points at the end of the game wins! Questions Laboratory knowledge / Safety 1. List three (3) lab safety guidelines a. Always wear goggles b.
