Uncovering the Unseen: Young Investigators Solve Mystery at the Forensic Science Workshop
On February 22, 2025, seven young investigators, aged 6-11 years old, embarked on an experimental journey to uncover the unseen through forensic science at the latest workshop by Leave a Nest Singapore. Designed to spark curiosity and problem-solving skills, the workshop encouraged children to “look closely, discover details, solve problems” through hands-on experiments.
The young participants stepped into the role of junior forensic scientists to solve an exciting mystery: Who stole the cookies? Armed with scientific techniques, they pieced together clues, analysed evidence, and ultimately uncovered the culprit behind the missing treats.
Hands-on Investigation Begins
The session began with an interactive icebreaker led by workshop leader Addi. Through a fun “Finding Wally” activity, the students were introduced to the importance of paying close attention to details—an essential skill for forensic scientists.
Once warmed up, the mission of the day was unveiled. Three suspects were present when the cookies disappeared, and at the crime scene, a handwritten note and a mysterious fingerprint were found. The students had to analyse the evidence and identify the culprit.
Scientific Techniques in Action
The participants conducted two forensic experiments:
Paper Chromatography – Identifying the Ink
To determine which suspect’s pen was used to write the note, the young scientists performed paper chromatography on three different pens and compared the ink separation patterns. They discovered that black ink is composed of multiple colours and observed how water carries different ink components upward due to cohesion and adhesion. By analysing molecular weight differences in the ink’s separation, they were able to eliminate one suspect from the investigation.
Fingerprint Analysis – Unmasking the Culprit
Addi introduced the three main fingerprint patterns: loop, whorl, and arch. The students first examined their own fingerprints by pressing their fingers onto a glass surface, then used black powder to dust the surface, making the latent fingerprints visible. After carefully lifting the developed fingerprints with tape, they compared them under close observation.
The students also learned that fingerprints are unique due to factors such as genetics, skin growth rate, blood flow, and even pressure in the womb. Finally, they used the same dusting and lifting method to analyse the suspect’s fingerprint, matching it to the evidence and uncovering the cookie thief
Mystery Solved, Cookies Enjoyed!
With their combined forensic skills, the junior investigators successfully identified the culprit and solved the case. To celebrate their detective work, they enjoyed chocolate chip cookies!
This engaging workshop not only introduced children to fundamental forensic techniques but also reinforced the importance of observation, critical thinking, and scientific inquiry in everyday problem-solving.
