FIRST® LEGO® League Season Challenges
Every year, FIRST® LEGO® League releases a new Challenge based on a real-world, scientific theme.
Starting with Discover, children are introduced to the fundamentals of STEM while working together to solve fun challenges and building models using LEGO® DUPLO® bricks.
As participants progress into Explore, children will take their background knowledge of STEM and put it into practice as they work in teams to design and build robots using the LEGO® Education SPIKE Essential.
Once they are ready to move into a competitive setting, they join Challenge and apply their STEM skills combined with critical thinking to work with a team, build a robot, and compete in an exciting, mission-based robotics game.

Family Engagement
Families who participate together in FIRST LEGO League discover the power of curiosity, creativity, and problem solving, building the foundation for life-long confidence in STEM learning.

Building Instructions for the UNEARTHEDTM Season
How do I build the Mission Models?
- Sort the LEGO element bags (found in your Challenge Set box) by bag number. They are labeled.
- Match the bag numbers with the corresponding bag numbers below.
- Open the correct pdf files and have an awesome time assembling the models. We strongly recommend opening one set of bags at a time so elements are not mixed up.
- Have fun!
