During a science fair, students presented various projects to an audience of parents and teachers. One student, Jake, demonstrated a volcano that erupted with a mixture of baking soda and vinegar. After his presentation, Jake explained his project’s significance, emphasizing how understanding chemical reactions can help in fields like medicine and environmental science. The audience was impressed not only by the eruption itself but also by Jake's eloquent explanation of the underlying principles of chemistry and their real-world applications.
