Ink & Paper Analysis in Document Forensics

Transform your classroom into a high-tech forensic laboratory! Ever wondered how a single drop of ink or a stray paper fiber can solve a multi-million dollar forgery case? This comprehensive, no-prep unit on Ink & Paper Analysis in Document Forensics gives your students the tools to become real-life forensic document examiners.

This is far more than a simple worksheet. This is a complete, scaffolded investigative journey that challenges students to move beyond memorization and into genuine critical thinking and scientific analysis. Students will step into the role of a trainee at the Forensic Science Laboratory, learning the core principles of document examination and then applying them to solve complex, multi-layered case studies.

From the chemistry of ink separation to the history hidden in watermarks, this unit covers the essential techniques used by experts to uncover forgeries, date documents, and expose lies written on paper.

This All-Inclusive Unit Contains Three-Parts in One PDF:

The Investigator’s Manual (Part 1): 10 pages of detailed, engaging reading passages covering four critical pillars of document analysis:
Thin-Layer Chromatography (TLC) of Inks
Paper Fiber Analysis & Microscopy
Document Dating Techniques (Chemical Aging)
Watermark Examination
2. The Student Workbook (Part 2): A 20-page, 10-worksheet training module that

builds skills progressively. Activities include:

Foundational terminology and concepts.
Procedural competency for TLC labs.
Calculating Retention Factors (Rf values).
Analyzing microscopic and chemical test results.
Synthesizing evidence in two capstone case studies: “The Forged Will” and “The Historical Artifact.”
3. Visuals & Teacher Resources (Part 3): Everything you need for seamless instruction and assessment!

3 High-Quality Visual Anchor Charts: Perfect for lab reference and classroom display (TLC Mechanics, Examination Protocol, Document Dating Timeline).
A Comprehensive 12-Page Answer Key: Detailed solutions and explanations for all 10 worksheets, saving you valuable prep time.
Perfect for in-class instruction, sub plans, homework, or a capstone project, this resource is designed to be flexible, engaging, and rigorously scientific. Equip your students with the analytical skills they need to succeed in STEM and beyond!
