- Complete the table by examining your own fingerprints with a hand lens and counting how many of each pattern type (Arch, Loop, Whorl, Composite) you have across all ten fingers.
- Compare your fingerprint patterns with a friend’s to identify any similarities or differences in their distribution.
- Conduct a class survey by collecting data from classmates on their fingerprint patterns, then add a new row to the table to record the total counts for each pattern across the entire class.
- Analyze whether your class results match general population statistics (e.g., arches common in African Bushmen/Central Europeans, whorls in Australian Aboriginal/Mongolian groups), and consider reasons for discrepancies such as small sample size or genetic diversity.
- Create a histogram using your class data to visually represent the proportion of each fingerprint pattern type among students.
- Write a summary based on your histogram describing which patterns are most and least common in your class.
- Read the provided paragraph explaining that fingerprints form in the womb during the third or fourth month, when foetal pads swell and skin wrinkles to create ridges; larger pads typically form whorls, medium pads form loops, and smallest pads form arches. Note that once formed, patterns remain unchanged except due to severe injury.
