The Applied Health Sciences theme has three main topics, namely forensic science, sports science and dental science.
After attending forensic science STEM applied learning lessons, students’ perspective widens. No longer limited to perceptions formed when watching the Crime Scene Investigation (CSI) television series. In order to relate the skill sets learnt to real life scenarios, students work on a car crash or murder case study.
Forensic materials to work on during a car crash scene.
In the car crash scenario, students are expected to document the scene by analysing the skid and yaw marks, examining the headlights, identifying fabric traces and conducting alcohol test on driver. As such, students get first-hand experience working like the forensic scientists and engineers. They shall eventually determine if the car crash was an accident so as to identify the culprit.
Other activities are crime scene processing, detecting blood traces and fingerprints. They have fun conducting facial biometrics profiling, DNA profiling and teeth imprinting. Not to forget collecting footwear and fingerprinting evidences, blood typing/splattering, digital microscopy and chemical analysis. There are also engineering hands-on activities that include building UV counterfeit detector, lie detector and burglar alarm from scratch.
With regard to sports science STEM focus, it is a hybrid of health and sports science. Students learn to measure body fat, lung capacity and VO2 max (the maximal amount of oxygen an athlete can consume when exercising at the maximum capacity). They will also learn to appreciate the reasons for the need to replenish salt and water after a strenuous exercise. They will understand how muscles and centre of gravity work when they exercise.
Demonstration of a heart rate sensor.
One of the hands-on projects students get to do is building heartbeat sensors to measure heart rates when engaged in different activities. Another fun project is to study the different features of sports shoes by cutting them into halves! Other project may include a series of progressive lessons equipping students with Scratch for Arduino- a simplified programming software.
In order to create solutions for better lives, students build an occupational therapy device by combining basic wiring and connection skills. A device that requires head/spine injury patients to use cognitive/spatial reasoning skills together with some hands/fingers repetitive movements to encourage hand-eye coordination and left/right brain interactions.
Another real-life example is the loss of limbs. One solution is to build a muscle-controlled prosthetic hand to improve people’s quality of life.
Building a muscle-controlled prosthetic hand.
In the dental science area, students are introduced to four main topics- biofilm and plaque, saliva, toothbrush design and forensic dentistry. In the biofilm and plaque topic, students observe oral bacteria under the microscope. After conducting the Gram staining experiment, bacterial species can then be differentiated into two different types. The types are Gram-positive and Gram-negative bacteria. In the dentistry forensic aspect, some hands-on activities include documenting lip prints and bite marks. From these activities, students get to experience and witness how every individual’s forensic traces are unique.
