Hair/Fiber/Fingerprint Re-Test is a Grade 11 science worksheet that reviews foundational forensic science and textile concepts through 15 questions: 14 multiple-choice items and one multiple-select item. Students identify the three basic fingerprint patterns, define hair structures such as the cuticle, recognize the telogen phase, and classify hair without a follicle and fibers as class evidence. They also distinguish fibers, yarns, textiles, natural fibers, and synthetic fibers, including classification questions about polyester and fiberglass and a burn-test application. This free printable worksheet with an answer key helps teachers check whether students can recall terminology, interpret fingerprint pattern images, and apply classification rules to forensic materials. It works well as a review or re-test after instruction on hair, fiber, textile, and fingerprint evidence. The varied question formats reveal whether students can recognize visual patterns, select accurate definitions, and distinguish closely related evidence categories.

This Grade 11 science worksheet uses 14 multiple-choice questions and one multiple-select question to review fingerprint pattern identification, hair anatomy and growth phases, forensic evidence types, and fiber and textile classification. Students identify arches and whorls, define the hair cuticle, distinguish class evidence from other evidence types, and classify materials such as polyester, natural fibers, fiberglass, and synthetic fibers.
Use the worksheet after direct instruction as a structured review: begin with the fingerprint pattern items, then model the difference between a fiber, yarn, and textile before moving to hair anatomy and evidence classification. Ask students to explain why hair without a follicle and fibers are classified as class evidence, and have them justify their natural-versus-synthetic choices using the worksheet’s examples, including polyester and the burn-test item.
Students may confuse a fiber with a yarn or textile, or misidentify the pictured arch and whorl patterns. Watch for students labeling hair without a follicle or fibers as individual evidence, treating polyester as natural, or selecting multiple material categories when the polyester item requires only the synthetic description. The answer key also identifies fiberglass as natural, so review that classification if students apply a different rule.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 15 items. Grade printable submissions by scanning student work with the Wayground for Teachers app, or use the digital quiz to collect responses electronically.
Use the worksheet’s Advanced Settings to adjust font spacing and font size so the fingerprint identification items and classification choices are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language while preserving its multiple-choice and multiple-select format.
