Enrichment Activities
Activity Days
In addition to our regular curriculum programs - Higher Education Studies and VCE subjects - we also offer full-day enrichment programs (Activity Days) for high-ability students around Victoria.
Algorithmics – The CHES Coding Challenge
In semester 1, students learned computational and algorithmic thinking to tackle a series of increasingly complex real-world problems. Working collaboratively across three sessions, students developed problem-solving strategies and explored key programming concepts while strengthening their logical reasoning and algorithm design.
Next dates: Friday 11 September and Friday 30 October
English Language – Language Under the Microscope
Students explored the nature of language, examining questions such as what makes human communication unique, how English has evolved, and the role of grammar, spelling and new forms of digital communication. The workshop provided an engaging introduction to the kinds of ideas explored in VCE English Language.
Next date: Friday 6 November
Extended Investigation – Beyond the Obvious: Don't Believe Everything You Think
Students who attended the first workshop learned how to develop research questions, evaluate evidence, and apply critical thinking frameworks to investigate complex issues. The day provided a practical introduction to the skills and mindset developed through VCE Extended Investigation.
Next dates: Friday 28 August and Friday 30 October
Specialist Mathematics – Mathematical Thinking
Designed for high-ability Years 9 and 10 students, this activity day challenged participants with rich, open-ended mathematical problems that encouraged creativity, rigorous reasoning and collaborative investigation. No advanced mathematical knowledge was required—just high levels of numeracy, curiosity and a willingness to embrace challenging problems.
Next dates: Friday 28 August and Friday 6 November
CHES Students Shine in VCAA Plain English Speaking Award (PESA)
CHES is proud to recognise the outstanding participation of our students in this year’s VCAA Plain English-Speaking Award (PESA). The competition challenges students to demonstrate excellence in public speaking through both a prepared speech and an impromptu speech. In the impromptu section, students are given an unseen topic and just four minutes to prepare before delivering a clear and persuasive three-minute response. The experience provides a valuable opportunity for students to strengthen their communication skills, think critically under pressure, and present ideas with confidence and clarity.
We congratulate all participating students for their enthusiasm, commitment and willingness to challenge themselves through this enriching program. Special congratulations go to Hayley K, who was named the CHES heat winner and went on to represent the school at the VCAA State Semi-Finals.
Programs such as PESA play an important role in developing students’ confidence, oral communication skills, speech-writing abilities and critical thinking, while providing opportunities to connect with like-minded students from across Victoria.
Many thanks to Amy Lee, CHES Leading Teacher of Enrichment, for her expert coordination.
Model United Nations
As part of Harmony Week, CHES partnered with UNAA Victoria to deliver both onsite and online Model United Nations (MUN) experiences, bringing together students from across Victoria to engage in global dialogue, debate and diplomacy.
Our onsite Model United Nations welcomed students from a wide range of schools who represented countries with confidence, respect and impressive diplomatic skill. With Adrian Morrice serving as Secretary General, delegates participated in thoughtful discussions on international issues, negotiated amendments, and debated complex topics including nuclear energy. Highlights included creative references to World of Warcraft and a memorable moment when the Saint Kitts and Nevis delegation successfully passed a new amendment.
Throughout the day, students demonstrated the ability to listen carefully, challenge ideas respectfully, and collaborate with maturity and purpose.
CHES also proudly hosted our inaugural Online Model United Nations, enabling students from regional and remote Victoria to take part in the experience. Led by Carlisle Richardson in the role of Secretary General, delegates explored the theme of space, stepping confidently into their roles as country representatives. Students representing Lithuania, Uruguay and India stood out for their strong diplomatic skills as they articulated national perspectives, engaged in respectful debate and negotiated complex issues with clarity and confidence.
Both events showcased the enthusiasm, critical thinking and communication skills of participating students, while highlighting the value of bringing young people together from diverse backgrounds to discuss issues of global significance. Through Model United Nations, students gain valuable experience in public speaking, negotiation, collaboration and leadership—skills that will serve them well in their future studies and beyond.
CHES extends its thanks to UNAA Victoria, Adrian Morrice and Carlisle Richardson for their leadership and support in delivering these outstanding Harmony Week experiences.
