Getting Ahead

BTEC Level 3 Extended Diploma in Forensic Science & Criminal Investigation at South Downs Campus

This course is intended to provide an educational foundation for those of you wishing to start a career as a Forensic Scientist, including roles such as Crime Scene Investigator, Forensic Psychologist, DNA Analyst, and roles within The Police Force.

You’ll dive deep into crime scene analysis, examine trace evidence, explore digital forensics, and understand criminal psychology – all within a practical, legal context. Our programme helps you build the critical thinking and analytical skills you’ll need for university study in Forensic Science or Criminology. It also lays strong foundations for career pathways in law enforcement and the justice system.

The content delivery is supplemented with practical activities to allow you to develop the associated technical skills for the workplace.

Welcome to your first forensic challenge! As future forensic scientists, you’ll learn that evidence is everywhere, often hidden in plain sight, and that every detail tells a story.

Your task is to capture a series of 5 – 10 photographs that tell an “unseen story” about something in your environment related to science, the human body, or photography itself.

For each photograph, you should provide:

  1. A Title: A creative title for your photograph.
  2. Scientific Explanation: A brief paragraph (approx. 50-100 words) explaining the scientific principles, anatomical features, or photographic techniques that are in your image.
  3. Forensic Connection: A short sentence or two explaining how this “unseen story” or the evidence it represents could be relevant in a forensic investigation.

 

Possible Themes & Ideas to Inspire You (Choose ONE theme for your set of photos):

Theme A: The Science of Decay & Change

  • Focus: Observe the natural processes of decomposition, erosion, or biological change.
  • Ideas:
    • A forgotten fruit: Photograph a fruit (e.g. apple, banana) over a week or two, showing its decomposition at different stages.
    • Weathered material: Capture close-ups of eroded stone, rusted metal, or peeling paint, highlighting the effects of natural forces.
    • Plant growth/decay: Document the life cycle of a small plant or the decay of leaves.
  • Forensic Connection: Understanding decomposition rates is important in forensic taphonomy (time of death).

Theme B: Human Traces & Biological Uniqueness

  • Focus: Explore the ways our bodies interact with the environment and the unique biological markers we leave behind.
  • Ideas:
    • A “hidden” fingerprint: Take a close-up photo of a latent print on a common surface (e.g., a glass, a polished table – you won’t see it perfectly, but you can use subtle smudges or reflections).
    • Hair diversity: Capture different types of hair (your own, a pet’s, a family member’s) up close, noting colour, texture, and other visible characteristics.
    • The ageing hand/face: Photograph the subtle lines, wrinkles, or veins that reveal age or individual characteristics.
    • Footwear patterns: A close-up of the unique wear pattern on the sole of your shoe.
  • Forensic Connection: Fingerprints are unique identifiers; Hair can provide DNA and racial characteristics; Facial features aid identification; Footwear impressions link suspects to scenes.

 

Theme C: The Art & Science of Photography as Evidence

  • Focus: Experiment with photographic techniques that forensic photographers use to capture detail, highlight features, or control light.
  • Ideas:
    • Macro photography: Use your phone’s macro mode to capture extreme close-ups of small details (e.g., fabric weave, insect wing, a grain of sand).
    • Lighting for detail: Experiment with side lighting or oblique lighting to reveal texture and shadows on a flat surface (e.g. dust on a table, writing on paper).
    • Depth of Field: Photograph an object with a very shallow depth of field (blurred background) to make a specific piece of “evidence” stand out.
  • Forensic Connection: Forensic photography relies on precise techniques to document evidence accurately, ensuring clarity, detail, and proper scale for court.

 

Submission Guidelines:

  • Content:
    • Your name and chosen theme
    • For each of your photographs:
      • The high-quality image itself
      • Title
      • The Scientific Explanation (50-100 words)
      • The Forensic Connection (1-2 sentences
  • Deadline: You will bring your photographs to Induction Week (first week of term).

 

Why This Work is Important:

This task isn’t just about taking pictures; it’s about developing the observational skills, critical thinking, and scientific curiosity that are absolutely essential for a successful career in forensic science. We look forward to seeing your unique perspectives!


My time at the college was definitely life changing, I have learnt a lot of new skills, and obviously it’s a completely new experience. The support was great, there was always people there to help and try make it as easy as they can for you. The college is really fantastic, it has helped me on the way to get to what I want to achieve within my career goals.
