Exciting hands-on activities, engaging intellectual challenges, and surprising scientific experiments all came together to create the Science Fair “Science Journey Through Time” at The Dewey Schools Cau Giay.
The vibrant performance of Grade 5 TDSers to the lively tune of “ZOO-ZOO-PI-A” marked the official opening of the event. Carrying that energy forward, the Science Show experience zone led students from one surprise to another. Acting as the event’s “spark,” the “Smoke Gun” experiment captured students’ attention with the fascinating movements caused by air pressure. Taking on the role of young scientists, students observed phenomena, formed hypotheses, and explored the underlying causes. Through this hands-on approach, physics experiments became the starting point for understanding the world through a scientific lens.
The journey continued through a system of interactive stations designed as a “science map through time,” guiding TDSers to explore five civilizations: Ancient Egypt, Ancient Greece, Rome, Ancient China, and the Future World.
At each station, students combined play and learning by participating in a variety of practical challenges. From calculating centers of gravity to build pyramids using paper cups, to navigating space with compasses or controlling drones, every activity required observation, experimentation, and adjustment to find solutions. Minh Chau (Class 5 Casablanca) excitedly shared: “I loved making a lemon battery the most. I never thought a fruit could light up an LED. At first, I couldn’t connect the wires properly, but after carefully observing the positions of the copper and zinc strips, the light turned on. Suddenly, science felt so interesting and easy to understand.”
Ms. Bich Huong, parent of Hoai An (1 Bangkok), shared: “The event sparked my child’s curiosity about science. Instead of passively watching, my child began asking ‘why’ questions about the principles behind each phenomenon. What surprised me most was the change in daily habits—my child now actively uses the iPad to research and learn more about scientific topics encountered at school.”
✨ The Science Fair provided TDSers with enriching and enjoyable learning experiences. More importantly, it placed students within a “learning cycle”: from curiosity to experimentation, reflection, adjustment, application, and deep understanding. When a child becomes curious enough to ask “why,” and motivated enough to seek answers, that is when true learning begins.
