Student worksheet
The main packet. Quick checks, guided application, and extended reasoning, with answer space built in. Prints in black and white, roughly 95 minutes of work.
Free teaching materials for classrooms that may not have specialist staff or spare prep time: an AI course that shows the arithmetic, and four full years of high school chemistry.
Program 01, new. Thirty-three lessons, beginner to advanced.
Thirty-three lessons, beginner to advanced. Most writing about artificial intelligence either flatters the reader or drowns them. This one teaches the mechanism: the formula, the worked arithmetic, and the measured number from the paper that reported it.
Program 02. K–12 chemistry.
Most classroom material about science is written either for specialists or for nobody in particular. It assumes equipment a school may not have, background a student may not have, or preparation time a teacher certainly does not have.
We start from those constraints. Every worksheet prints in black and white, works without a device, and can be taught by someone who is not a subject specialist. Each packet names its standards, its running time, and what it assumes students already know.

What each week contains.

The main packet. Quick checks, guided application, and extended reasoning, with answer space built in. Prints in black and white, roughly 95 minutes of work.

Harder problems for students who want them, written in the style of olympiad and contest questions but tied to the same week's topic.

A short read that puts the week's chemistry somewhere real. No prerequisites, no problem set, meant for students who ask why this matters.
Every packet is checked before release.
