Why are fireworks so colourful? What power does static electricity contain? What kind of microorganisms are found around us?
SUIS Qingpu High School students recently held a science fair event, and in addition to the fair, the event included a knowledge bee quiz, a trebuchet contest, and a sci-fi movie night. The most popular part of the event, though, was the science fair itself, an activity that brought every student into a wonderful world of unknowns!
In the “Build a Biodome” project, students created a climate control system in an enclosed bottle garden. They also programmed the microcontroller to optimize the environmental conditions for both plants and animal life.
In the “Flame Test” project, students demonstrated the beautiful flame colours of different metal ions. They also explored the reason why different metals have different flame colours. The fireworks we see on special occasions also use the same scientific principle.
In the “Static Electricity” project, students explored and demonstrated the basics of static electricity. They performed various demonstrations such as using static electricity to move objects.
In the “Build a Trebuchet” project, four groups built their trebuchets based on projectile motion. In the science fair week, they competed on accuracy and distance using their machines.
In the “Microbe Investigation” project, students investigated microbes from different places such as the toilet, canteen, classrooms, labs, and even human skin. Students also made cell models from various materials.
In the “Sand Casting” project, students put molten pewter into a kinetic sand mold to obtain small items with different shapes.
When students completed the explorations for their projects, they then attended a Science Q&A session where they were tested on what they had learned. Small prizes were awarded for the best answers.
Science is always changing our lives! It also inspires human curiosity and encourages us to keep exploring!
