Science relies on creative thinking. As the famous American philosopher and educator John Dewey once said, "The great advances of science have come from new and bold imaginations."

Haidian Kaiwen’s Science Fair has arrived, eagerly anticipated by our students! The events are novel, engaging, and educational, aiming to foster creativity and scientific literacy. Throughout the fair, fresh, bold, and innovative ideas left everyone in awe, showcasing the limitless power of innovation!

For this Science Fair, each team meticulously planned their projects, from selecting a theme, researching scientific principles, to designing and conducting experiments. Every group worked collaboratively, advancing their projects methodically. Now, let’s open our curious eyes and step through the doors to the magical world of science!

01

"Facemask on Pig’s Skin"
Authors: Simon Huang, Daniel Shen, Alex Xiao, Kayden Yang

In today's society, more people use facemasks for hydration and beauty. Our group chose this topic because skincare products, especially moisturizing masks, are widely used. We selected pigskin for our experiments due to its structural similarity to human skin, including the epidermis, papillary, dermal, and reticular layers.

02

"Change in Color: Apple Slices during Oxidation"
Authors: Candy Chu, Katie Hu, Sophie Liu, Eva Shen

Oxidation is a common phenomenon in daily life. For instance, apples contain polyphenol oxidase (PPO), which reacts with oxygen in the air, causing enzymatic browning when the apple is cut. The appearance of food affects our taste perception, as the visual cortex in our brain is activated by seeing appealing food. Our experiment focused on preventing rapid food oxidation to maintain its visual appeal.

03

"Bacteria in Everyday Life"
Authors: Simon Huang, Daniel Shen, Alex Xiao, Kayden Yang

According to The Paper, 13.6% of the 2019 global deaths were related to 33 common bacterial infections, amounting to 7.7 million deaths. Given the right nutrients, temperature, and humidity, bacteria can grow at an alarming rate. Our bodies, akin to microbial factories, produce 100 to 100 trillion bacteria daily. This experiment identifies the most bacteria-laden spots in daily life, such as keyboards, toilet seats, and door handles, promoting health awareness.

04

"Origin of Life"
Authors: Krystal Zhang, Elly Cui, Felix Chen, Summer Wang

How did life originate on Earth? Was it sheer luck and magic that created humans and other life forms? This question sparked intense debate about the origins of life. Some believe life arose from chemical combinations on early Earth, while others think it was a blend of luck and time. Guided by the question "How did life begin on Earth?" our group expanded our research, exploring the unknown past.

05

"Time Travel"
Authors: Mumu Zhang, Alan Lian, Fiona Cai, Martin Ma

Time travel is often considered a fantasy, akin to jumping into a "time machine" to revisit the past. Humans have long imagined using time travel to achieve unattained dreams. For most, time travel involves different perspectives of time. Einstein’s theories of special and general relativity describe space and time. According to Einstein, time may flow differently for different observers. Our research aims to verify the feasibility of time travel by connecting relativity and time flow, supported by explanations of relativity, time dilation, and space-time relationships.

06

"Medicines and their Expiration Dates"
Authors: Ashley Liang, Annie Wu, Shawn Wei, Jessica Yang

Some medicines remain effective even after expiration, but due to various factors, some must be used cautiously. Before delving into this topic, we explain what happens when medicines expire. For most medications, using them post-expiration may reduce their efficacy in treating certain conditions. Key factors affecting a medicine’s effectiveness include storage conditions and the medicine's form. Solid medicines are generally stable, whereas liquid medicines may harbor bacteria post-expiration.

07

"Earthquake Resistant Architecture"
Authors: Ian Chen, Albert Du, Emma Han, Philip Wang

Earthquake-resistant architecture is crucial for safety, especially in quake-prone areas. Building codes dictate that earthquake-resistant structures must withstand the maximum anticipated earthquake at their location, aiming to minimize loss of life by preventing structural collapse. We attempted to create models of earthquake-resistant buildings and simulated how they withstand quakes, observing how different structures bear the forces.

08

"Claw Crane"
Authors: Jennifer Xing, Jenny Li, Cynthia Zhao

Claw crane machines are popular entertainment devices that provide fun through simple operation. We aimed to understand the principles of hydraulics using everyday examples. Utilizing the nature of liquid pressure transfer, we measured mass based on the principle of balanced liquid levels and pressure equality, integrating these concepts with the mechanics of claw crane machines.

09

"Pyrotechnic Colorant"
Authors: Angela Liu, Martina Ding, Candy Wu, Jinzhao Che

Imagine fireworks shooting into the night sky, bursting into a rainbow of colors. This beautiful scene is a result of the mechanism behind pyrotechnic colorants. Based on the principle of flame coloration, various colors can be produced. Flame colors, typically red, blue, orange, yellow, or white, depend on the chemical additives used.

10

"McDonald’s Reaction with HCl Acid"
Authors: Cathy Chen, Lydia Hong, Zoey Liu, Mia Zhang

In this experiment, we immersed McDonald's food in acid to observe its effects on food quality. We chose this topic to explore how our stomachs digest food, examining the relationship between different foods and digestion.

11

"Chicks Hatch without Shells"
Authors: Tracy Cui, Selina Mi, Selina Wang, Cheryl Zhang

Eggshells, like a mother's womb, protect fragile new life. It’s commonly believed that hatching without a shell is impossible. Based on research into shell-less hatching, we created a sterile environment to simulate the hatching process. Our experiment tested how different calcium lactate levels affect egg development, potentially applying shell-less hatching methods to daily livestock farming.

12

"Birth of a Tsunami"
Authors: Carly Hu, Leo Yin, Linda Zhang, Bruce Mu, Angela Mu

Tsunamis are massive waves caused by undersea earth movements or volcanic eruptions, generated by waves colliding at specific frequencies. By showcasing the impact of different terrains and dikes on seawater, and scaling down tsunami simulations, we gain a closer understanding of tsunami mechanisms.

More Exciting Moments

At this Science Fair, students combined academic knowledge with practical applications, experiencing the fun of science in a more realistic way. This ignited a strong interest in academic research among Haidian Kaiwen students. We hope every student carries this invaluable experience throughout their academic careers, always keeping their love for science close to their hearts!

Haidian Kaiwen’s middle school science curriculum references the Next Generation Science Standards (NGSS). Developed in 2013 to improve science education, NGSS spans the entire K-12 system, covering the breadth of elementary science, middle and high school physics, chemistry, biology, geography, and general technology standards in China. Overall, science is divided into three parts: life science, earth science, and physical science. Life science includes topics like plants and animals, ecosystems, cells and genetics, reproduction, the human body, and diseases; earth science covers earth’s structure, rocks, energy, climate, earth changes, and astronomy; and physical science encompasses chemistry and physics.

Our science teachers employ exploratory learning methods, focusing on Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts. Inquiry-based learning is a student-centered teaching approach, diverse in its execution. Unlike traditional teacher-led instruction, it emphasizes the process of exploring new knowledge, finding solutions, and planning actions, with students taking the lead and teachers guiding them. Cross-disciplinary learning integrates knowledge, treating students as central figures who construct meaning and correct their understanding through organized, planned inquiry-based learning, unlike traditional education where subjects are isolated and unrelated.
