Improving and consolidating existing authentication systems in schools [P]
Create a Facial Recognition Door Lock With Raspberry Pi [C]
Person Identification by Voice Spectral Analysis [E]
Determine which characteristic of typing is most unique and will yield a better biometric: times in between keystrokes or length of time keys are held down. [P] [P]
Compare two colors (monochrome and contrast) and see which one is better for iris pattern analysis. [E]
2D and 3D Biometric: Recognizing Humans by Their Ears [E]

Forensic Entomology

A Forensic Study on the Effects of Seawater on the Growth Rate of Local Sarcophagid and Calliphorid Larvae [E]
Maggot Mass Temperature and ADH (Accumulated Degree Hours) [E] [E]

Bloodstain Pattern Analysis (BPA)

Simulate a crime scene using fake blood, and predict where the blood-shedding event occurred, using blood-spatter analysis. [E]
Learn about forensic science by performing balloon spatter experiments. [E]
Determine which blood substitute would best match the spatter patterns and drop stain patterns of real blood, so that a blood substitute may be used in an active investigation. [E]
Determine whether the materials used or the heights from which blood is dropped affect the diameter of the resulting spatter. [E]
Determine whether the materials on which the blood is dropped or the heights from which it is dropped affects the diameter and shape of the resulting spatter. [E] [E] [E]

Forensic Anthropology

Study the science of mummification by mummifying a hot dog using baking soda. [E]
How did the Ancient Egyptians Mummify? [P] [P]
Identification by Dental Structures [E]
Identification by Hair Analysis [E]
What environmental factors favor decomposition by soil microbes [E]
Forensic Determination of Crime Suspects by Lip Prints and Chromatography [E] [P] [P]

Forensic Chemistry

Crime Scene Chemistry: The Kastle-Meyer Test for Blood [E]
Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance [E]
Investigate how temperature affects the blue glow created by the chemical luminol. [E]
How ink can help forensic scientists to catch criminals. [E]
Demonstrate paper, gas and liquid chromatography (forensic chemistry). [E] [E] [E]

Lineup Identification

Testing for Bias in a Photo Lineup [E]
Find the most accurate type of criminal identification lineup (sequential lineup, sequential lineup field, simultaneous lineup, simultaneous lineup field). [E] [E]
Determine if the method of identification used in a photo line up, simultaneous method (viewed all at once) vs. the sequential method (viewed one at a time), affects the accuracy of the eyewitness identification. [E]

Eyewitness Identification

Examining whether gender, distance from subject, and delay in recollection time affect the accuracy of eyewitness reporting. [E]
Eyewitness Accuracy in Children [E]
Find out which is a more effective method of crime solving, eyewitness accounts or handwriting analysis. [E]
Find out how accurate observation is done by eyewitness. [E]
Confidence and Accuracy in Eyewitness Identifications [E]


Fingerprint Science Fair Projects & Experiments


Determine whether or not memories change over time, leading to wrongful convictions. [P]
Measure the rate of heat loss from an orange (representing a body) and see how it depends on the temperature of the surroundings. [E]
Cryogenic Roses: Can ice be used to preserve once-living things? [E]
