What is FIRST ® LEGO® League Jr.?

Guided by adult coaches and FIRST LEGO League Jr. Core Values, students build models using LEGO® Education WeDo and create Show Me posters to present what they learned.

The program focuses on building interest in science, technology, engineering, and math (STEM) through a real-world challenge – to be solved by research, critical thinking, and imagination.

Each year, FIRST LEGO League Jr. presents a new and exciting Challenge to ignite the creativity of children age 6 to 10 and introduce them to the excitement of STEM and learn the skills linked to the engineering design process.

In the 2017-18 AQUA ADVENTURE Challenge, teams around the globe were asked to:


  • How they use water at home or in their community, the water’s journey, and how to improve a part of this journey.

Create and Test

  • Teams designed, built, programmed, tested, and improved a Team Model to show their chosen water use, the water’s journey, and their idea for how to improve a part of the journey.
  • Teams used the AQUA ADVENTURE Inspire Model (a LEGO® water pump) in their design. They also used LEGO® Education WeDo to build and program at least one motorized part of their Team Model.


  • Share what they learned by participating in an Expo. They could also opt to hold an open team meeting and present their LEGO model and Show Me poster to family and friends.
