Objective

By the end of this lesson, you will be able to understand the basic principles of biology and how they relate to criminology.

Materials and Prep

• Pen and paper
• Internet access for research
• Textbook or online resources on biology
• Curiosity and enthusiasm!

Activities

1. Research and discuss the role of DNA in forensic science.

   Use the internet or your textbook to find information about how DNA analysis is used in criminal investigations. Write down key points and examples that you find interesting.

2. Explore the concept of fingerprints and their uniqueness.

   Take your own fingerprints using an ink pad or pencil lead. Examine the patterns and ridges on your fingers. Research why fingerprints are considered unique to each individual and how they are used in crime scene investigations.

3. Investigate the field of entomology and its role in forensic science.

   Learn about the study of insects and how they can provide valuable information in criminal investigations. Research the stages of insect development and how they can be used to determine the time of death in a crime scene.

Ninth Grade Talking Points

• "Biology is the study of living organisms and their interactions with each other and their environment."
• "Forensic science is the application of scientific knowledge and techniques to investigate crimes and analyze evidence."
• "DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for the development and function of all living organisms."
• "DNA analysis can be used to identify individuals, establish family relationships, and solve crimes by comparing DNA samples found at crime scenes with known samples."
• "Fingerprints are unique patterns of ridges and valleys on the fingertips that are formed during fetal development and remain the same throughout a person's life."
• "Fingerprint analysis is a common method used in forensic science to identify suspects and link them to crime scenes."
• "Entomology is the scientific study of insects, including their biology, behavior, and ecological roles."
• "In forensic entomology, insects found on or near a body can provide valuable evidence to determine the time of death, the presence of drugs or toxins, and other relevant information in a criminal investigation."
