Your Ninja trained their own AI models and built real machine-learning projects this week — there's a lot to celebrate!
The hardware and project files stay at the dojo. Your Ninja walked you through their favorite AI builds at our Friday Camp Celebration — keep that conversation going at home and ask them to retell their proudest moment of the week.
What We Covered This Week
Throughout the camp, Ninjas explored how AI actually works — not just how to use it, but how to train their own models — using Google Teachable Machine, Machine Learning for Kids, micro:bit V2 with CreateAI, Scratch, and AI art & music tools. Click any topic to expand.
What is AI? Smart Watch & First Models
Learned the 3-step ML process: Get Data → Train Data → Use Data
Trained a dance-recognizing AI with Google Teachable Machine — then tested it with other ninjas dancing (it usually broke!)
Met two big concepts: underfitting (not enough data) and overfitting (AI learns the wrong pattern)
Built a motion-tracking Smart Watch with a micro:bit V2 — trained classes for "exercising" vs. "not exercising"
Wrapped with an AI Art Prompt Battle using Craiyon — class voted on whose prompt produced the best image
Rock-Paper-Scissors: Supervised vs. Unsupervised
Warmed up with Quick, Draw! — Google's AI doodle game that demonstrates the data-then-prediction loop
Learned the difference between supervised learning (labeled training data) and unsupervised learning (find patterns without labels)
Built a webcam-controlled Rock, Paper, Scissors game in Scratch — trained Teachable Machine to recognize hand gestures
Took it further with an unsupervised version where the computer learns from opponent moves to play smarter
Neural Networks: Cargo Dash & Virtual Pet
Toured neural networks — input layer, hidden layers (where the calculations happen), and output layer
Compared neural networks vs. decision trees — two different ways AI makes choices
Built Cargo Dash — a Scratch game controlled by hand gestures through the webcam
Built a Virtual Pet that responds to voice commands — the AI listens, classifies what was said, and reacts
Generative AI: Ninja Storyteller & AI Art
Explored generative AI — AI that creates new things (images, text, music) instead of just classifying
Compared GANs vs. Diffusion models at a kid-friendly level — the two big approaches behind tools like Craiyon
Built a Ninja Storyteller — an AI that generates short stories from prompts
Practiced prompt engineering — the difference between a vague prompt and a great prompt
Wrapped with Say What You See — describing scenes so the AI can recreate them
AI Ethics, Final Project & Camp Celebration
Took on the AI Ethics module — copyright, responsible AI use, what AI can and can't do
Played a Kahoot AI review — revisited every concept from the week
Built a Final Project of their own design — their own ML model, their own training data, their own goal
Wrapped with an AI Music Showcase using Suno AI / AIVA — original AI-generated music to close the camp
Presented their Final Project at the Friday Camp Celebration — parents came to see every ninja's AI build
What's Next?
Want your ninja to keep building? Code Ninjas® West Katy's CREATE program turns the spark of camp into a year-round 9-Belt journey — from white belt to black, building real games week after week with their own Code Sensei®. New students can start with our Summer of Code promo: 2 months for $299, ages 8–14. Promotion ends June 30.
