The feet can measure the height

Hurumanu - The feet can measure the height.


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:  To use forensic science techniques to measure the height of a criminal.

Material:

  1.  measuring tape
  2. yourself

Steps:

  1.  Get your measuring tape.
  2.  Get your self and some one else.
  3.  Then your buddy to measure you.
  4.  
  5.  

Findings:


Name
Foot  (cm)
Height (cm)
Sam25 centre metres151 centre metres
Odin24 centre metres150 centre metres
Elias25 centre metres152 centre metres

15 is the number used by investigators to determine a persons height based on their feet. This is because 15% of a persons height is the length of their foot.

Find out what percentage of your height is your feet. To do this you need to:
Divide the length of each person's foot by his/her height then multiply it by 100. 

15 is the number used by investigators to determine a persons height based on their feet. This is because 15% of a persons height is the length of their foot.

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are:

  1.  Pool
  2.  Oil 
  3. Water

Materials

2. scissors
3. Filtering paper
4.Pebbles
5. Dirty water
6.Sand
7.
8.

Process - ( use verbs or doing words in each step )


Step 1

Cut the bottle in half

Step 2

Put the top half upside down in the other half

STEP 3

Add layers of  sand

STEP 4

Get 1 cup of dirty water 

STEP 5

Pour the dirty water into the funnel

Conclusion:
My groups first attempt with filtering the water didn't go so well because we mightn't of put the filtering paper in the bottle properly But the second attempt our water that we experimented with came out nearly perfect see through
