Half-Life of M&Ms Essay

IntroductionHalf-life is the time required for something to f all to one-half its sign value. The half life of a radioactive element is the time it takes for half of its atoms to declination into something else. M&Ms were chosen because they all have the homogeneous m mark on the on one side. In this science lab you pull up stakes go through predicting and counting the number of be mark-side up candies that should help understand that rates of decay of unstable nuclei and how it can be measured that the exact time that a certain nucleus will decay cannot be predicted and that it takes a very large number of nuclei to finger the rate of decay. PurposeTo stimulate the transformation of a radioactive isotope with M&Ms all over time and to graph the selective information and plug in it to radioactive decay and half-lives.Materials and SafetyMaterials* 200 pieces of M&Ms (trademark only)* Shoe Box* Pen/Pencil* Paper TowelSafety- No safety precautions neededProcedure1. Cou nt bulge 200 M&Ms. Place all 200 candies in the shoe box with the letter facing up 2. Cover the box and shake it modishly for 3 sec. This is 1 time interval. 3. Remove the lid and take out any atoms (candies) that have decayed, that is, that are now showing garner sides down. read on the data table the numbers of decayed and stay atoms. 4. Replace the cover on the box, and shake for another 3-sec time interval. Record the number of radioactive atoms remaining. 5. Keep repeating time interval trials until all atoms have decayed or you have r distributivelyed 30 sec on the data table 6. Repeat the whole experiment a bet on time, and record all data. 7. Average the number of atoms left at each time interval from both trial. Make a graph of your data showing the average number of atoms remaining versus timeConclusion1. later how many time intervals (shakes) did one-half life of your atoms (candies) decay? Trial 1- 1 interval Trial 2- 1 interval2. What is the half-life of your candies?3 secs3. If the half-life model decayed perfectly, how many atoms would be left after 12 sec? 12.54. If you increased the amount of atoms (candies), would the overall manufacture of the graph be altered? Maybe, the amount of M&Ms that are flipped over after shaking is always a gamble and you never recognize what youre going to get Graph of the average number of atoms remaining versus time.Conclusion8. After one shake, which is one time interval, almost half ouf our atoms decayed. 9. The half life of the cadies is three seconds. 10. If this experiment had been conducted perfectly, 12.5 atoms would be left. 11. No, overall the shape wouldnt change it would may become a slight disklike or steeper but the dominate shape of the line would not change 12. The experiment did not work perfectly. The percentages came pretty close to 50%. Some were way off, but for the most part they were close to 50%. From 3 to 12 secs was the closet to 50% than the other time intervals. From 18 to 30 secs the percentage started to steer father from 50%. I mean this happened because the less amount of candies or atoms the less chance the atoms will decay.
