DNA Forensics

The application of genetic testing for legal purposes

DNA forensics is a branch of forensic science that focuses on the use of genetic material in criminal investigation to answer questions pertaining to legal situations, including criminal and civil cases.

CSI - The Experience Web Adventure

Description: This is a game-like activity where kids can follow the experts from the TV show CSI to learn about how forensic science helps solve crimes.

Labs & Experiments

Crime Scene Investigation (CSI) with Powdery Mildew Fungi

Description: This exercise can be used to stimulate the investigative nature of your students as they use forensic plant pathology techniques with powdery mildew cleistothecia (the sexual stage of powdery mildew fungi) to prove their innocence in a mock murder investigation.

Teacher Resources

DNA - A Molecular Identity (Lesson Plans/Lesson Activities)

Description: This lesson plan engages students in learning what DNA is and about different DNA profiling techniques. Students examine three real cases where DNA evidence was an essential component and evaluate the benefits and possible misuses of DNA information.

Entomology in Action (Lesson Plans/Lesson Activities)

Description: Lesson plans and teaching aids on entomology

Forensic Entomology (Lesson Plans/Lesson Activities)

Description: Lesson plans, work sheets, and teaching aids on forensic entomology

Forensics (Lesson Plans/Lesson Activities)

Description: This module teaches shows students how DNA is analyzed by forensic scientists in order to link a DNA sample to a particular individual. To do this, forensic scientists use powerful molecular biology techniques such as PCR, restriction digests and gel electrophoresis. To learn more about DNA and how it is used by forensic scientists, students will isolate their own DNA from saliva. Using their new-found understanding of DNA and forensics techniques, students will help solve the case of the missing mascot.

Using QR Codes in Forensic Science (Lesson Plans/Lesson Activities)

Description: In this lesson, students use mobile technology and knowledge of forensic science to research a crime case.


Can Science Stop Crime

Description: A NOVA program on how science is being used to identify criminals and anticipate crimes before they happen
