OneSchool Global Trio Pioneers New Insights into Supercool Water Behavior

In a remarkable feat for young scientists, students from OneSchool Global's campuses in Sydney, Australia, and Hastings, New Zealand, have published their original research on supercooled water in the Japan Journal of Research. This achievement underscores the power of student-led inquiry in unraveling fundamental physics principles. The paper, titled 'On The Survival Curve of Repeated Nucleation of a Single Volume of Supercooled Water,' authored by Thomasin Fooks, Kelsie Kennard, Makana Senior, and their mentor Dr. Peter Wilson, explores the probabilistic nature of ice formation in supercooled states. For aspiring researchers eyeing careers in physics or materials science, this story highlights pathways from high school labs to professional research jobs.

Supercooled water, also known as supercooling, refers to liquid water chilled below its normal freezing point of 0°C (32°F) without solidifying into ice. This metastable state occurs because freezing requires nucleation—a random event where water molecules align to form an ice crystal embryo. Without impurities or agitation to trigger nucleation, the water remains liquid, defying intuition. The students' work delves into repeated nucleation cycles, plotting a 'survival curve' that quantifies how long a water sample resists freezing under controlled supercooling conditions.

Meet the Young Researchers Behind the Publication

Thomasin Fooks and Kelsie Kennard, both from OneSchool Global Sydney, teamed up with Makana Senior from the Hastings campus in New Zealand. These high school students, participating in the school's innovative STEM Scholars Program, conducted experiments that caught the attention of international peers. Their collaboration exemplifies global connectivity in education, bridging Australia and New Zealand through shared virtual platforms.

Makana Senior's contribution from Hastings adds a distinctly Kiwi perspective. OneSchool Global Hastings, a modern composite school serving the Hawke's Bay region, fosters self-directed learning that prepares students for university-level challenges. Parents and educators in New Zealand often seek environments that nurture curiosity, much like those leading to higher education career advice resources.

Unpacking Supercooling: The Science Explained Step-by-Step

To grasp the students' innovation, consider the supercooling process. Pure water in a clean container can supercool to -10°C or lower before freezing spontaneously. The key is homogeneity—no nucleation sites like dust or scratches.

• Step 1: Distill water to remove impurities, ensuring ultra-pure samples.
• Step 2: Place in a sealed vial or test tube, often with a thermocouple for precise temperature monitoring.
• Step 3: Cool gradually in a controlled freezer or Peltier device to avoid mechanical shock.
• Step 4: Observe supercooling depth (ΔT below 0°C) until nucleation triggers rapid freezing (latent heat release warms to 0°C).
• Step 5: Thaw completely, repeat cycles, and record nucleation temperatures statistically.

The students extended this by hundreds of cycles on the same water volume, revealing patterns in nucleation probability. This builds on classic experiments while adding novel statistical analysis.

The Experimental Breakthrough: Survival Curves in Action

The core finding is the 'survival curve'—a plot showing the probability a water sample survives N supercooling attempts without freezing. Modeled exponentially, it reflects nucleation's stochastic nature. For instance, after 10 cycles, survival might drop to 37% (e^{-1}), aligning with Poisson statistics.

Using simple lab gear like a programmable freezer and data logger, the team documented spreads in freezing temperatures, challenging assumptions of uniform behavior. Real-world implications span atmospheric science (supercooled clouds causing aircraft icing) to biology (cryopreservation of cells without ice damage).

In New Zealand's context, where variable weather drives interest in cloud physics, such research resonates. Universities like the University of Canterbury study similar phenomena, offering bridges to postdoc opportunities.

STEM Scholars Program: Catalyzing Global Student Research

Launched in 2024 by Dr. Peter Wilson, OneSchool Global's Secondary Teacher and Adjunct Professor at institutions including the University at Albany, the STEM Scholars Program engages dozens of students weekly. With 43 participants from 35 campuses in its inaugural year, it focuses on themes like water-ice dynamics.

Fortnightly Zoom sessions enable cross-country collaboration, from proving the Mpemba effect (hot water freezes faster due to supercooling) to hydrophobic coatings. Dr. Wilson's guidance—'explore how the world works'—transforms curiosity into publishable science, rare for high schoolers where fewer than 1% achieve journal publications.

Dr. Peter Wilson's Mentorship: From Classroom to Journal

Dr. Wilson, with expertise in nucleation dynamics, co-authored the paper, validating student data. His dual role in K-12 and adjunct academia exemplifies mentorship pipelines to higher education. Quotes from him emphasize: 'To be published at such a young age is fantastic... their curiosity shines.'

For New Zealand educators, this model inspires integrating research into NCEA science, boosting enrollment in STEM fields where completion rates hover around 47% per OECD data.

Why This Matters: Applications of Supercooling Research

Beyond academia, supercooling enables ice-slurry cooling for athletes, extended food shelf-life without freezing damage, and organ preservation. Recent advances preserve red blood cells at -13°C for weeks, per Nature studies. The students' survival curve informs scalable systems, potentially aiding NZ's biotech sector.

Challenges and Triumphs in Student Publishing

High school publications are scarce; predatory journals abound, but peer-reviewed ones like Japan Journal of Research (open-access multidisciplinary) demand rigor. The trio navigated revisions, statistics, and ethics, gaining skills for university labs.

In NZ, disparities exist—low-decile schools lag in STEM by 2.5 years—but programs like this level the field, preparing for competitive university jobs.

Implications for New Zealand's STEM Landscape

Hastings' success spotlights regional potential. With NZ prioritizing STEM via initiatives like COMET Auckland, such stories recruit talent to unis like Victoria University of Wellington. Future outlooks: students pursuing physics degrees, contributing to climate modeling where supercooling affects precipitation.
