Domain I covers Scientific Inquiry, Processes & Safety — 10% of the TExES Science 7-12 (236) exam and the foundation every other domain builds on. This KAB Strategic Certification Readiness Lab manual breaks down all 3 official competencies (lab and field safety, the nature of scientific inquiry, and the history and impact of science) in plain English, with real-world analogies, common-mistake call-outs, and practice questions with full rationale — not just an answer key.

No jargon walls. No guessing which answer TEA is actually looking for. Just the exam, explained the way you wish someone had explained it the first time.
