After all the hard work of bringing in materials and making our poster board, we finally presented it on the day of the science fair! I would like to reflect and share how my group's project went. Our project was the reaction between coke and mentos. Our independent variable was the coke. Our dependant were the different flavors of mentos. Our constants were the meter sticks, the coke and the mentos.
The only thing that I knew about my topic before we started researching was what actually happened in the experiment. These are the things that I wanted to find out-
- What caused the reaction?
- What ingredients are in mentos that cause the explosion?
- How high can the explosions really go?
Throughout the resarch process, I learned so many cool things about our project. For example, suprisingly enough, the reaction is actually a physical reaction, not a chemical. Also, to answer one of my earlier questions, it is not an ingredient in mentos, it is actually the tiny pores in the mentos that make the carbon dioxide go in them and make the coke flow more easily out of the bottle. So, during my research all of my questions were answered. A new question I have the I did not research is if the type of soda/fizzy drink affects the explosion. My plan for my future science expirement is to work alone. I think that I will work alone because I might be less distracted and more focused on only my project. One of my favorite parts of this expiriment, not counting the fair, was probably preparing the board and doing the actual expirement. I feel like one of my core value strengths are being innovative and being innovatine while making this posterboard was really important. Doing the actual experiment was actually really cool too, because we where able to see that coke and mentos could really go up 3 meters! One of the more frusturating things in my group was disagreeing about certain things. We had problems sometimes with having an odd number of people because it sometimes felt like there was an odd one out. If I could change anything, I might have changed the script lines, because sometimes in certain presentations, there was someone who had less lines than others. During the science fair, I tried to project my voice as much as possible, because I know that that is one of the things I struggle with. I know that our collaboration was as big a challenge as anything else because there was an odd number of us, and we had to evenly divide and conquer. We also ran into quite a few disagreements as a group, but were aable to overcome them by calmly talking them out. In the end, I was kind of half satisfied, half not satisfire with my topic. I liked it because it was intersting and there was a lot to learn about, but I disliked it because there were a lot of different groups doing it, so it was not really origional. When we were about to present, I felt kind of nervous, but then I realized that I knew all the information. I liked the QR code system because it was really organized and it was not handwritten, although there were some irrevivent comments, not really focusing on the project as much.
Overall, this was a great experience and I am so excited for next year!
