UK Chemistry Olympiad
Age: 16–19
Registration: open
Deadline: 14 January 2026
Designed to challenge and inspire, the UK Chemistry Olympiad (UKChO) is a unique opportunity for students to push themselves further and excel in the chemistry field. Budding chemists will develop critical problem-solving skills, learn to think more creatively and get a chance to test their knowledge in new, real-world situations. They could even find themselves representing the UK at the prestigious International Chemistry Olympiad.
The UKChO consists of two rounds. In round one, students sit a written paper designed to test chemical knowledge through a written test with real-world chemistry problems. This is sat at school. In round two, between 25–30 of the top scoring entrants attend a residential weekend of of lessons and demonstrations on new topics from respected academics, teachers and technicians, followed by theoretical and practical assessments. Four entrants will then be invited to represent the UK and the International Chemistry Olympiad.
The UK Chemistry Olympiad is open to all secondary schools and colleges in the British Isles. However, the questions are aimed at students in their last year of study before higher education so we recommend that entrants should be at least 16.
TeenTech Awards
Age: 11–16
Registration: open for 2026
The TeenTech Awards encourage students to see how they might apply science and technology to real-world problems across several different categories, from food and retail through the future of transport to wearable technology. Students identify an opportunity or a problem, suggest a solution and research the market.
Students can work in teams of up to three people and there are lots of award categories. All submitted projects receive feedback and a bronze, silver or gold award. The event is well supported with training sessions for teachers and students, so everyone knows what to expect and what the judges will be looking for!
The best projects go forward to the TeenTech Awards Final for judging and the winning school in each category will receive a cash prize.
The UK CanSat Competition
