JUNEureka 2026: Secrets of the Sunken is running at Science Centre Singapore from 29 May to 28 June.
The Science Centre frames the activity around Ocean Recon Cadets, or ORCa, giving the June holiday programme a mission-led ocean-science hook for visitors aged nine and above.
What The Quest Is About
Instead of treating ocean science as a display-only topic, JUNEureka turns it into a challenge with characters, clues and a search for secrets below the surface.
That format is useful for older primary-school children because it gives them something to solve while still touching on marine environments, observation and scientific curiosity.
- Dates: 29 May to 28 June 2026.
- Venue: Science Centre Singapore.
- Recommended age: 9 years and above.
- Theme: Secrets of the Sunken.

Why It Works For The Holidays
The best school-holiday activities do more than fill time. They give children enough structure to stay engaged while leaving room for discovery.
JUNEureka fits that brief because the official page presents the programme as a quest rather than a lecture. It can sit alongside other Science Centre exhibits if you want a longer visit.

Planning Notes
Science Centre Singapore can get busy during school holidays, so build in time for ticketing, food and moving between zones. Families combining this with Snow City or Omni-Theatre should check session times before arrival.
The strongest way to use JUNEureka is to set one mission for the child before starting. Ask them to notice one creature, one technology clue and one question they want answered. That turns the quest into a learning trail instead of just a sequence of stations.
If you are visiting with mixed ages, let the older child lead the clue-solving while younger siblings handle simpler observation tasks. That keeps the group together without forcing every child to engage with the same level of detail.
