Two complete curricula are free to download: Curriculum A (30 weeks, ages 8–14) and Curriculum B (high-school engineering lab, grades 9–12). Student workbooks, the Teacher's Guide, and bundles are one-time PDF purchases. Project packs and hardware are sold separately.
Curriculum A (30-week plan) + Student Workbook A + Teacher's Guide. Three PDFs, one download. Curriculum A is also free below.
Curriculum B (high-school engineering lab) + Student Workbook B + Teacher's Guide. Three PDFs, one download. Curriculum B is also free below.
Both curricula, both student workbooks, and the Teacher's Guide covering A and B.
Printable student pages for Curriculum A (ages 8–14): build logs, data tables, and reflection prompts.
Printable student pages for Curriculum B (grades 9–12): lab notebooks, calculations, and design reviews.
Pacing, answer keys, safety notes, and assessment guidance for both curricula.
Complete digital pack: build guide, SVG/DXF cut files, first-principles lessons, Arduino sketch, BOM. Five-digit laser-cut birch plywood apprenticeship — keepable machine, not cardboard craft. Choose individual maker $12 or Homeschool / Co-op $39.
$39 = Homeschool / Co-op pack (sample path). $12 = individual maker pack. Same Hand core files; $39 adds the co-op facilitator addendum.
New · High school (grades 9–12). Build a barometric + IMU flight logger for a model rocket, predict apogee from thrust and drag, then compare the prediction with the logged flight.
New · High school (grades 9–12). Each pack is a digital guide with cut files, BOM, code, labs and teacher materials. Hardware is sourced separately (see the BOM on each pack page).
Individual $17 · Homeschool / Co-op $39 (one family, or a co-op of up to 10) · Classroom $59 (one teacher, up to 30 students). Buy on each pack page.
