Forensic Science Simplified Course

Lesson 1 • Ethics and Professional Standards

Defines impartiality, objectivity, and reporting obligations for forensic professionals. Prepares students to navigate conflicts of interest and bias in casework.

Lesson 2 • Legal Framework for Forensic Evidence

Explains admissibility standards, expert witness roles, and chain-of-custody requirements. Grounds technical work in the legal expectations practitioners must meet.

Lesson 3 • Scientific Method in Forensic Contexts

Applies hypothesis-driven inquiry to crime-related questions. Connects scientific reasoning to the reliability standards required in forensic reporting.

Lesson 1 • Scene Documentation Techniques

Teaches photography, sketching, and note-taking methods that create a permanent scene record. Accurate documentation supports reconstruction and courtroom presentation.

Lesson 2 • Evidence Packaging and Labeling

Details proper containers, labeling conventions, and packaging materials for diverse evidence types. Prevents contamination and supports chain-of-custody documentation.

Lesson 3 • Evidence Search Patterns

Introduces systematic search methods suited to different scene types and sizes. Ensures no area is overlooked and evidence is located efficiently.

Lesson 4 • First Responder Protocols

Covers immediate actions upon arrival, including scene safety and perimeter establishment. Sets the foundation for all subsequent evidence-collection activities.

Lesson 1 • Trace Evidence Collection Methods

Covers tape lifts, swabbing, vacuuming, and manual picking for trace recovery. Proper technique prevents loss or cross-contamination of minute materials.

Lesson 2 • Impression Evidence Examination

Covers casting, lifting, and comparison of footwear, tire, and tool marks. Links physical impressions to specific objects through class and individual features.

Lesson 3 • Glass, Soil, and Paint Analysis

Examines refractive index, elemental composition, and layer structure of common trace materials. Results place suspects or objects at specific locations.

Lesson 4 • Fiber and Hair Examination

Applies microscopy and chemical testing to compare fibers and hair samples. Findings establish contact between persons, objects, and environments.

Lesson 1 • ABO and Serological Typing

Explains blood group systems and their historical role in forensic casework. Contextualizes serology within the broader shift toward DNA-based identification.

Lesson 2 • Biological Evidence Preservation

Details drying, refrigeration, and storage protocols that maintain DNA integrity. Improper handling degrades samples and can invalidate downstream analysis.

Lesson 3 • Identification of Biological Fluids

Teaches presumptive and confirmatory tests for blood, saliva, semen, and other fluids. Accurate identification determines which samples warrant DNA analysis.

Lesson 1 • Forensic DNA Databases

Describes national DNA index systems, upload criteria, and hit confirmation procedures. Database searches link unknown profiles to known offenders or unsolved cases.

Lesson 2 • STR Typing and Capillary Electrophoresis

Explains short tandem repeat amplification and fragment separation by capillary electrophoresis. This is the primary method used in forensic DNA laboratories worldwide.

Lesson 3 • Mixture Interpretation

Addresses deconvolution of multi-contributor profiles using peak height ratios and probabilistic genotyping. Mixture analysis is among the most complex tasks in forensic DNA work.

Lesson 4 • Specialized DNA Techniques

Introduces Y-STR, mitochondrial DNA, and touch DNA analysis for challenging samples. Expands the analyst's toolkit beyond standard autosomal STR profiling.

Lesson 1 • Principles of Forensic Toxicology

Establishes dose-response relationships, pharmacokinetics, and specimen selection criteria. Provides the scientific basis for interpreting concentration data in casework.

Lesson 2 • Poison and Toxin Detection

Examines heavy metals, cyanide, carbon monoxide, and plant toxins using targeted analytical methods. Findings support cause-of-death determinations in suspected poisoning cases.

Lesson 3 • Forensic Chemistry of Controlled Substances

Identifies and quantifies seized drugs using color tests, spectroscopy, and chromatography. Purity and weight data directly affect legal charging decisions.

Lesson 4 • Alcohol Analysis Methods

Covers headspace gas chromatography and enzymatic assays for ethanol quantification. Connects analytical results to impairment thresholds used in legal proceedings.

Lesson 1 • Postmortem Changes and Time of Death

Covers livor mortis, rigor mortis, algor mortis, and decomposition stages for time-of-death estimation. Accurate estimation narrows investigative timelines significantly.

Lesson 2 • Medicolegal Death Investigation System

Describes the roles of medical examiners, coroners, and scene investigators in death cases. Clarifies jurisdictional responsibilities and case intake criteria.

Lesson 3 • Special Death Investigation Scenarios

Addresses infant deaths, fire fatalities, and decomposed remains requiring specialized protocols. Prepares students for complex cases beyond routine autopsy practice.

Lesson 4 • Manner and Cause of Death Classification

Distinguishes natural, accidental, homicidal, suicidal, and undetermined manners of death. Classification requires integrating pathological, toxicological, and scene findings.

Lesson 1 • Quality Assurance in Forensic Laboratories

Covers accreditation standards, proficiency testing, and corrective action procedures. Quality systems underpin the reliability of every report and testimony delivered.

Lesson 2 • Communicating Statistical Evidence

Explains likelihood ratios, random match probabilities, and verbal equivalents for non-expert audiences. Accurate statistical communication prevents juror misunderstanding.

Lesson 3 • Principles of Forensic Report Writing

Establishes structure, objectivity, and precision standards for forensic laboratory reports. Well-written reports reduce misinterpretation and strengthen evidentiary value.

Lesson 4 • Handling Cross-Examination

Develops strategies for responding to challenges on methodology, error rates, and bias. Confident, accurate responses protect the integrity of forensic findings.
