  2. Group 2 Group 4 Project

  3. How does it take to start and finish the rate of reaction where a substrate (mentos) are placed in different types of soft drinks? Will the amount of the substrates affect the reaction? And will the temperature affect the explosion? Research Question

  4. Hypothesis

  5. There are many factors that can affect the reaction of the explosion: • Temperature of the soft drink • Different type of sodas • The amount of mentos General Hypothesis

  6. Amount of mentos will affect the duration of the reaction Different sodas will affect the height of the reaction explosion Bio & Chem’s Hypothesis

  7. Cold temperature will lessen the reaction Hot temperature will ignite a higher reaction Constant room temperature will act as a medium of the reaction Physics hypothesis

  8. Variables

  9. Pandu and Akhsa Chemistry’s Variable

  10. Mentos – during the three trials, amount of metos will be different due to the reason that it is needed for chemistry to see which amount (5 piece, 10 piece, or 15 piece) has the greatest reaction Independent Variable

  11. The duration of the reaction when different amounts of Menthos react with sodas Dependant Variable

  12. Size of Menthos- Each piece of mentos will have same shape and size. This will allow equal chance for every soda to have a reaction. Temperatures- The liquid will be placed under the same room temperature 24*C to keep a steady reaction not to boost or slow down the reaction, more than the mentos will. Volume- The Liter (L) of the solution will be the same (1,5 L) so everything would be equal in having the opportunity to react. Control Variable

  13. Jazzlyn and Vidi Biology’s Variables

  14. Type of Soda – The different type of soda will provide different height of the reaction. By changing the soda’s, there will be different amount of sugar that will contribute to the reaction of the CO2.. This will help to the extent whether each soda will have different height and duration of the reaction. Independent Variable

  15. The effect of the different sodas on the reaction with Mentos. This will show a trend of the reaction rate, in order to draw a general conclusion whether the different amount of mentos will affect the soft drinks. • The duration of the reaction Mentos give to the different sodas. This will determine whether the type of the soda will affect the rate of the reaction. • The height of the mentos explosion. This will determine whether the amount of the mentos really affects the height of the explosion rate. This variable is essential to gather a constant range of data’s. Dependent Variables

  16. Sizes of Mentos - each package of this candy when sold will be weighted to a specific number, meaning each piece that is presented in the round but flat form has the same size. This will allow equal chance for every soda to have a reaction. • Temperatures – the liquid will be placed under the same room temperature (24°c) to keep a steady reaction not to boost or slow down the reaction, more than the Menthos will. • Volume – the liter (L) of the solution will be the same (1,5 L) so everything would be equal in having the opportunity to react. ControlLED Variable

  17. Alif and Adika Physics’ variables

  18. Temperature – different temperature can affect the time and height of reaction Independent variable

  19. Time of reaction – to show that if that temperature affects time of reaction Height of reaction – to show that temperature affects the height of reaction Dependent variable

  20. Amount of mentos – 5 Type of mentos – mint Type of soda – coke zero Volume of soda – 425ml Controlled variable

  21. General MAterials

  22. 5 Rolls of Mentos Mint • Bucket • Stopwatch • 20 cm Ruler • 9 different 1.5 Litres soft drinks • 3 Coca – Cola Zero • 3 Regular Sprite • 3 Fanta Orange Materials

  23. 9 Coca Cola Zero (425 mL sized) • Thermometer 2x • Refrigerator • Ice Cubes 500 mL • Waterbath • 500 mL Beaker • 500 mL of water • Hotplate Materials Exclusive for Physics

  24. General Procedure

  25. Prepare all materials Place one bottle of 1.5 Liters of soda on a flat surface Prepare the mentos (depending on the amount could range from 5, 10, & 15 mentos) Place the ruler at the neck of the bottle Open the bottle Quickly insert the mentos Start counting the stopwatch Measure the height with the ruler Record the data Repeat for 3 trials to get optimum data. General Procedure

  26. Prepare all the 9 mini Coca Cola Zero • Put 3 drinks inside a frige and cool it until 15*C • 3 will need to be heated by using a water bath • Fill 500 mL of water in the 500 ml beaker • Heat the water filled beaker by using a hotplate • Place thermometer • Wait until the water bath is 60*C • Then place the Coca-Cola Zero inside of it for 10 minutes Physics Procedure

  27. 4. While waiting for the heating and cooling process place 5 mentos inside of the “room temperature” Coca Cola Zero 5. Measure the height and time when the reaction occur 6. Repeat the step with the cold and hot coke zero Physics Procedure Cont’d

  35. Physic’s Processed Data

  36. TIME From the Graph above, we can see that as the temperature of the Coke Zero increases, than the time of the reaction from start to finish will be shorter. From the graph, we can also see that the random error is big; we can see this from the points that are not close to the best fit line. This random error is probably caused by the errors we make when we are doing the methods.

  37. HEIGHT From the first graph, we can see that as the temperature increases, than the height of the reaction also increases. However this data of the two variables are not directly proportional to each other. This can be proven as we see from the graph when the best fit line doesn’t intercept the origin which is 0.

  38. Conclusion

  39. Sprite has the highest average amount of explosion Fanta has the longest duration of the reaction Coke is in between of the two Reaction occurs because of the Nucleation process where CO2 fuse with the pores of the mentos to create the bubbles or foam Soft drinks with mentos is currently safe to enter your digestive system. Bio’s Conclusion

  40. Nucleation occurs when the mentos reaches the surface of the soda. The more mentosis inserted to the soda it is where the most and the fastest reaction is from When less mentos is inserted to the soda it is where the least and the longest reaction occurs Chemistry’s Conclusion

  41. Pressure is what helps an explosion occurs, not only that but the CO2 placed inside the bottle needs to go somewhere when opened or when reacting with mentos. Higher temperature means higher pressure Therefore, the higher the temperature is, the higher the height of reaction and the faster the time of reaction While, the lower the temperature is, the height would also be low and the time would be then longer than the usual. Physics Conclusion

  42. Overall Evaluation

  43. The strength of this experiment for all three discipline is that it turned out to be successful. With a table filled with results and by bringing all the specific and right materials. Not only that but the group collaborated well and accepted ideas from other members. Everyone overall did their job equally. The weakness is that we didn’t completely have the right procedures to do this experiment because of underestimating that it would be easy. So there were a slight miscommunication and lack of materials at first even in the end we were able to overcome it. What we would need to improve if were to do this again is one use a camera that would catch all the specific detail that an eye could not. Secondly, use gloves because the experiment could get messy. Then, we should bring an apparatus that could help us put the mentos in quickly and tidily not like how we did it before. Evaluation

  44. Many children are curious and do not know the real effect of combining soft drinks with mentos, even adults. That is why rumors have it that people could die consuming these two product together. So we did this experiment to research the real situation and also to help the society raise awareness. Giving better knowledge to whom who does not understand the effect of soft drink combined with mint candies. Impact to society
