Contest Details

Youth ages 8 to 18: Compete in our virtual building brick challenge series to show off your original builds with plastic building bricks like LEGO and MEGABLOKS! Each month, from October to December, we’ll offer a new build challenge to celebrate the launch of our new Creating with Building Bricks 4-H project. For our challenges youth create their own original builds following the month’s theme and size limits, then submit info on their build, along with photos of the build electronically. Each month, our favorite build (based on creativity, technical skills demonstrated, and alignment to theme) will be selected as the winner in 3 different age divisions:

• 8-10 year olds
• 11-13 year olds
• 14-18 year olds

Winners will receive prizes via mail. We’ll also select one random participant submission per month to receive some swag. There is no cost to enter, but youth MUST be currently enrolled Illinois 4-H club members to participate (enrollment for the 2025-26 4-H year starts October 1,2025!). 

Youth can only submit one build per month! All builds must be original (from the imagination of the youth who submits) and not built from a kit or inspired by the builds of others (including ones they see on the internet). Virtual builds are not permitted for this contest. Builds must be entirely from plastic building brick elements. Builds should also follow the copyright guidelines outlined in the Creating with Building Bricks project resource guide (pages 17 & 18). Youth who win their category one month will not be eligible for prizes any other month in the series. Age divisions go by 4-H age (youth age on 9/1/25).

December

• Theme: Habitat Build
• Build a LEGO habitat. A habitat is a small, diorama-style scene featuring 1 minifigure, built on an 8x8 plate base. Habitats are designed to be stackable. Habitat scenes show minifigures at work, home, and play! They are essentially individual "rooms" or spaces that can be connected to create a larger display.
• Size: Build must follow “habitat” rules, so it must fit on an 8x8 stud plate base and must have 2 walls that take up 1 stud each direction (if you don’t have a plate this size, you can build on a bigger plate or base plate and just keep your build contained to this size). Read these Habitat Tutorial Instructions from @brickfambuilds x bradyjoynerbricks or watch this Lego Habitat Tutorial YouTube video from Michael Shell for tips on how to create a habitat. Builds should only contain 1 habitat!
