- #2 Project Title and Team
- #3 The experiment titled 'COKE AND MENTOS' is a classic demonstration of a physical reaction between carbonated soda and Mentos candies. This project was created by Syed Zoraiz, Jon Cody Bill, and Omar Mohammad Nasef Ali Maklad. The purpose of this presentation is to showcase the steps, predictions, and outcomes of the experiment in a structured format. The experiment aims to explore the reaction dynamics, measure the height of the soda eruption, and analyze the behavior of Mentos when introduced into a carbonated environment. This introductory section sets the stage for understanding the scientific curiosity and teamwork involved in conducting the experiment.
- #4 Questions and Problems, Materials Required
- #5 Before conducting the experiment, the team formulated key questions to guide their observations: How high will the coke stream sprout into the air? How will the soda react with the Mentos? What will happen to the Mentos after being dropped into the soda? These questions are essential for setting clear objectives and understanding the expected outcomes. They also help in predicting the physical and chemical interactions that occur during the experiment. By focusing on these questions, the team ensures that the experiment remains structured and that observations can be linked back to the initial hypotheses.
- #6 The materials used in the experiment include: 2 liters of Coke, 5 Mentos candies, safety goggles for protection, a measurement stick to record the height of the soda eruption, a paper clip to tie the Mentos together, and a trash bin to support the soda bottle and prevent it from falling. Each material plays a critical role in ensuring the experiment is conducted safely and accurately. The Coke provides the carbonated environment, Mentos act as the catalyst for the reaction, and the measurement stick helps quantify the results. Safety goggles are essential to protect the eyes from any unexpected splashes.
- #7 Procedure, Predictions
- #8 The procedure begins with collecting all necessary materials and finding a safe outdoor location to avoid mess and ensure safety. The soda bottle is placed inside the trash bin for stability, and the measurement stick is attached to the bin for accurate height recording. Safety goggles are worn before starting the experiment. The bottle cap is unscrewed, and Mentos candies are tied together using a flattened paper clip. These Mentos are then dropped into the Coke bottle, initiating the reaction. Immediately after dropping the Mentos, the team steps back quickly to avoid getting soaked by the soda eruption. This sequence ensures both safety and successful execution of the experiment.
- #9 The team made several predictions before conducting the experiment: Carol predicted that the Mentos would dissolve completely in the soda. Anders believed that the Mentos would react with the bubbles, causing a rapid release of carbon dioxide. Carol also estimated that the soda stream would sprout approximately 54 cm into the air. These predictions reflect the team's understanding of the physical principles involved, such as nucleation sites on Mentos accelerating the release of carbon dioxide from the soda. Making predictions is a critical part of the scientific method, as it allows for comparison between expected and actual outcomes.
- #10 Experiment Outcome, Summary Paragraph
- #11 The experiment produced a dramatic and rapid eruption of soda, with the stream shooting higher than one meter into the air. The reaction was quick and intense, and most of the soda was expelled from the bottle, leaving only about half a liter behind. Contrary to one prediction, the Mentos did not dissolve completely; however, their outer coating partially dissolved during the reaction. These observations confirm that the reaction is primarily physical, driven by the rapid release of carbon dioxide gas from the soda when Mentos are introduced. The results highlight the importance of surface area and nucleation sites in accelerating gas release.
- #12 In summary, the Coke and Mentos experiment was an exciting demonstration of a physical reaction. The team carefully prepared the materials, selected a safe location, and followed the procedure step by step. The eruption was spectacular, exceeding initial predictions in terms of height and speed. The experiment provided valuable insights into the role of nucleation sites and the rapid release of carbon dioxide in carbonated beverages. It also emphasized the importance of safety measures, such as wearing goggles and conducting the experiment outdoors. Overall, the activity was both educational and enjoyable, reinforcing scientific principles through hands-on experience.
