Grade 3-5: AI teammates beat the Ender Dragon, a 9.8-second cube robot & 7 billion passkeys

This week on TechCheck for grades 3–5: university students in New Zealand built a robot that solved a 4x4 cube in 9.806 seconds, and Guinness still has to confirm it (word of the day: MECHATRONICS); four AI agents wrote their own code, split up jobs by chatting, and beat Minecraft's Ender Dragon after 27 hours (AGENT); Canada's new Children's Privacy Code says location tracking should start off and profiles should be private, and teens helped write a kid-friendly version (PRIVACY); INTERPOL's new campaign says Wait. Validate. Don't Take the Bait. (DEEPFAKE); and about 7 billion passkeys now let people sign in with a face, finger or PIN (PASSKEY). Vocabulary-rich and discussion-ready.
