    \r\n \t
  1. Obtain a bag containing 40 pieces of construction paper (20 each of 2 different colors) and 5 dice.<\/li>\r\n \t
  2. Separate the construction paper into 2 piles by color. Assign one color as A and one as B. This will represent the reaction A \u2194 B.<\/li>\r\n \t
  3. Set the B pieces of paper aside in the discard pile: We will begin with all A in our experimental pile (20 A, 0 B) as shown below. Notice the papers are organized in 4 rows with 5 pieces of paper each for easy tallying in your data section.<\/li>\r\n \t
  4. For each time stamp in the data section, you must roll for EVERY piece of paper. This means you will roll 20 times. For the first time stamp, you can ONLY roll for A since there are no B papers present. For each subsequent time stamp, roll for whichever paper you have. (You will roll for all 20 papers in the experimental pile EACH time). Pick up each piece of paper in order. Roll the dice to determine if it will react.<\/li>\r\n<\/ol>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n

    1. Roll for each piece of paper.\r\n
        \r\n \t
      1. If it is an A piece of paper:i. If you roll a 1-3, a reaction happens. Put each piece of A that reacts into the discard pile and replace it with a B in the experimental pile.ii. If you roll a 4-6, a reaction does not occur. Leave the A in the experimental pile.<\/li>\r\n \t
      2. If it is a B piece of paper:i. If you roll a 1, a reaction happens. Put each piece of B that reacts into the discard pile and replace it with an A in the experimental pile.ii. If you roll a 2-6, a reaction does not occur. Leave the B in the experimental pile.<\/li>\r\n<\/ol>\r\n<\/li>\r\n \t
      3. Once you have rolled for all 20 pieces of paper take a tally of what you have in your datasection. For example, your first time stamp may look like the image below. (This would be recorded as 15 A, 5 B in your data section). Then you can begin rolling again for a new time stamp using the rules above.<\/li>\r\n<\/ol>\r\n<\/div>\r\n<\/div>\r\n

For the first time stamp, you can ONLY roll for A since there are no B\u00a0present. For each subsequent time stamp, roll for whichever paper you have.

            1. For each A piece of paper:\r\ni. if you roll a 1-3, a reaction happens. Put each piece of A that reacts into thediscard pile and replace it with a B in the experimental pile.\r\nii. if you roll a 4-6, a reaction does not occur. Leave this A in the experimental pile.<\/li>\r\n \t
            2. For each B piece of paper:\r\ni. if you roll a 1-3, a reaction happens.

                      Experimental Procedure<\/p>\n

                        \n
                      1. Obtain a bag containing 40 pieces of construction paper (20 each of 2 different colors) and 5 dice.<\/li>\n
                      2. Separate the construction paper into 2 piles by color. Assign one color as A and one as B. This will represent the reaction A \u2194 B.<\/li>\n
                      3. Set the B pieces of paper aside in the discard pile: We will begin with all A in our experimental pile (20 A, 0 B) as shown below. Notice the papers are organized in 4 rows with 5 pieces of paper each for easy tallying in your data section.<\/li>\n
                      4. For each time stamp in the data section, you must roll for EVERY piece of paper. This means you will roll 20 times. For the first time stamp, you can ONLY roll for A since there are no B papers present. For each subsequent time stamp, roll for whichever paper you have. (You will roll for all 20 papers in the experimental pile EACH time). Pick up each piece of paper in order. Roll the dice to determine if it will react.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n
