Puxi Campus G2-3: A Celebration of Discovery at the Science Fair

November 24, 2025

The Grade 2–3 Science Fair filled our classrooms and hallways with excitement as students explored a wide range of hands-on experiments and demonstrations. The event transformed the school into a lively space of curiosity, where young scientists eagerly investigated the world around them through engaging and interactive activities. In the weeks leading up to the Science Fair, students followed the full scientific process to prepare their projects. They began by selecting a question, forming a hypothesis, conducting experiments, recording their procedures, and analyzing their results. After several weeks of investigation, they compiled their findings into posters or videos, which they proudly presented during the fair.





Students rotated through an impressive variety of experiments, each designed to spark wonder and deepen scientific understanding. Among the highlights were skittle color diffusion, dancing raisins, bouncy eggs, asteroid impact simulations, and the cookie dunk comparison test. Children also explored air and water challenges, tried balloon blowing investigations, observed floating and sinking predictions, experimented with pencil resistors, and learned about vibration and pitch. Visual illusions, demonstrations of tooth decay, and several other creative stations kept students thinking, questioning, and experimenting throughout the day.



One of the standout features of this year’s fair was the participation of our dedicated parent volunteers. Their demonstrations offered students an extra layer of excitement and real-world connection. Children gathered around to watch a dramatic baking soda volcano eruption, why mixing primary colors in paint differs from digital mixing, light-based color blending, a floating table experiment and learned how zinc and copper plates in salt water could power a small model car—an eye-opening introduction to how electric vehicle batteries work.


In addition to the experiments, students enjoyed Science Fair Bingo, searched the hallways for hidden beakers in a school-wide scavenger hunt, and visited a gallery walk of famous scientists. These activities added an extra element of fun and encouraged students to move, interact, and continue their learning between stations.





The Science Fair was a wonderful celebration of curiosity, creativity, and hands-on learning. As laughter and excitement filled the building, it was clear that students not only learned a great deal but also developed a deeper appreciation for how science shapes the world around them. The day was a joyful reminder of the power of inquiry—and the limitless possibilities that science brings to our classrooms.
