Description

What FIRST LEGO League Explore is

FIRST LEGO League runs a new theme every season, and this set ties into SUBMERGED, which focuses on ocean exploration and the technology researchers use to study life underwater. The Explore division is aimed at younger children who are not yet building the motorised robots seen in the senior FLL categories. Instead, teams put together a themed model and talk through what they learned about the topic, so the set works as a hands-on way into a real scientific subject rather than as a standalone playset.

667 pieces, two minifigures

The build totals 667 pieces made from 271 different parts, a mid-sized count that keeps a build session engaging without becoming a marathon project. Two minifigures add a bit of storytelling to the finished model, useful for teams that want to present a small scene alongside their explanation of the topic. The parts list on this page breaks every element down by colour and quantity, which is handy for checking what a team already owns before starting a session.

A colour scheme built for underwater tech

White, black, orange and medium azure make up most of the set, a combination that reads as equipment and safety colours rather than decoration. It suits models of research gear, vehicles or structures more than scenery, which fits the SUBMERGED brief of showing how people and technology operate below the surface. Builders who want to match or swap specific elements can check exact colour counts in the parts list rather than guessing from photos.

Who the set suits

This is a good fit for children just starting with FIRST LEGO League, for classroom groups exploring an ocean or environmental science unit, or for families who enjoy themed building outside any competition. No robotics experience is required, and the set stands on its own as a building project even without entering an event. Anyone assembling several FLL sets over the years can use the parts list here to plan colours and pieces across models.
