Marshmallow Sorter
The 16-session plan
Meet the Marshmallow Sorting Machine Explore how AI can recognize different marshmallow colors or types. See how Arduino can physically sort them.
Choose the Sorting Challenge Select two or three visually different marshmallow categories. Decide where each category should be sorted.
Build the AI Dataset Create the categories in Teachable Machine. Capture many images of each marshmallow type.
Train the Marshmallow AI Train the first model and test individual marshmallows. See which colors or shapes are easiest for AI to recognize.
Make the AI More Accurate Add images from different angles, positions, and lighting conditions. Retrain and compare the results.
Frequently asked questions
Who is this project a great fit for?+
BlueRobins projects are designed for curious students in Grades 3-12 who want to build. No prior experience is needed — mentors start wherever your child is and grow the challenge as they grow.
What does a typical session look like?+
Your child meets 1-on-1 with their mentor every week over Google Meet. Programs run 16 sessions of 45 minutes each. Sessions are hands-on from minute one — building, designing, coding, writing, experimenting — with the mentor coaching live, asking great questions, and unlocking the next step.
What will my child build by the end?+
A finished project they're proud of and can show the world. Across 16 sessions, your child turns an ambitious idea into a working app, prototype, research write-up, portfolio, or published artifact. Every student finishes with a completion certificate signed by their mentor.
Why a free trial first?+
So your child can meet their mentor, get a feel for the project, and leave the call excited. The trial is a complimentary 1-on-1 free trial session — no credit card needed. After the trial, you decide if it's the right fit. Most families know within the first 15 minutes.
