The Feet can Measure the Height.

The bones of the feet can tell a lot about a person. What do feet reveal about a person's height? Forensic anthropologists team up with law enforcers to help solve crimes.

Bones of the feet can reveal an interesting fact about an individual. Let's combine math with forensics to see how.

• Aim: Based on someones feet size we can measure their height.
• Hypothesis: A rough estimate of our height.
• Method: 

1. Have the students in your group remove their shoes and measure their height.
2. Measure the length of the adult's left foot from the wall to the tip of the big toe.
3. Examine the numbers. Do you see a pattern?
4. Divide the length of each person's left foot by his/her height. Multiply the quotient by 100. What do you get? You may also want to use the calculator on a computer for this activity

• Equipment:

1. One Metre Ruler
2. 30cm Ruler.
3. Calculator.

• Results: I found out my foot size, (22cm) was 15% of my heght, 146.
• Summary: The Police investigators and forensic scientists use 15% of a person's foot length because it is equal to their height.
• Conclusion: By knowing what a person's foot size is we can determine their approximate height.
