On Tuesday, June 25, witnesses gathered around what appeared to be the scene of a crime in the Keystone Secondary School hallway. Fortunately, this shocking scene that drew a crowd of onlookers was all fake and the school remained as safe as always. The fake blood was created with water, food coloring, and corn starch, a fake dummy victim made of foam and metal laid on the ground. This fascinating scene was just part of the Collaborative Sciences Project Exhibition, a culmination of collaboration between students in Grade 11.

Each piece of evidence carefully placed at the crime scene by the students – Cony Peng, Lena Wu, Lucy Wu, Oscar Zhou, and Tony He – represented one part of the comprehensive group work behind this Collaborative Sciences Project. The fake blood took hours of design work to perfect, the soil samples taken from different areas were carefully studied under a microscope using methodology from environmental science, chemistry was used to find the right chemicals to clean up the scene, and biology used to analyze the victim’s fake wounds. Even the images of possible suspects based on the clues and story the students had created were made using artificial intelligence and coding scripts from computer science. Each piece came together like a puzzle to create this look into the forensic science behind crime.

This was just one of the engaging topics student groups chose to work on for their projects this year. Another group, inspired by cinematic depictions of space travel, decided to study the possibility of creating a self-sustaining spaceship using various scientific approaches. The students, Jack Wang, Evelyn Zhang, Louie Wu, Julia Zhou, and Ella Dai, looked into the physics required for artificial gravity and nuclear-powered space flight, the biology and environmental science behind using aquaponics to create a whole ecosystem in space, the chemistry needed for oxygen and water recycling systems, the computer and data science that could support the ship ecosystem, and the best design for such a ship. Although ambitious, their project found that a lot of the science behind such concepts that are currently relegated to fiction may soon be possible in the not-so-distant future – perhaps even when they begin their own scientific careers.

While some groups were inspired to look to the future, others decided to travel to the past for their project ideas. Aileen Guan, Billy Song, Emma Gong, Feifei Chen, and Lucy An created a computer game featuring the extinct dodo bird, where players attempted to keep the bird alive both in the past and present, demonstrating how harmful effects on the environment from sources throughout all fields of science would likely cause the bird to go extinct a second time, even if it had miraculously survived until today. They decided to make a computer game for their project to disseminate this scientific information in a user-friendly and engaging manner. Their final product was on display at the exhibit, where players ran around a colorful environment and jumped over obstacles with a cute, pixel-art dodo bird.

Many other groups chose topics for their projects that were closer to home. Neo Ding, Henry Ye, Susan Huo, Elizabeth Xu, and Fiona Zeng researched sustainable solutions to the world’s pressing plastic problem, even creating their very own bioplastics that were biodegradable and made from used recycled kitchen materials. Their products were still drying out, but the bioplastic was already firm yet stretchy, similar to regular plastic but much more environmentally friendly both in creation and disposal. Harrison Pan, Shawn Shang, Annalucia Li, and Roseanne Huo designed and built a small-scale model of a next-generation greenhouse for sustainably growing tomatoes that could function both day and night and featured many unique ways to improve overall cultivation while still considering user experience of the gardeners. Ben Wang, Cyan Xing, Sophia Qi, and Oscar Chen did experiments testing the best way to provide clean drinking water for communities using water from the Keystone Eco-pond and several different purification methods including a control sample.

There were so many more unique and creative projects on display at the Collaborative Sciences Project Exhibition, each one demonstrating the thorough teamwork of the students and combining knowledge and skills from each area of science. While each student took on their project from one subject angle, the groups had to connect each subject into a greater project, learning from each other in the process. The skills the Grade 11 students gained through this project will stick with them through school and beyond, empowering them to work with others combining different fields and disciplines to create a more sustainable future.
