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.

Lily	28 cm	164  cm

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.

Aim: To look at the different types of fingerprints.

Materials: 

1.   ink 
2.   balloon
3.   finger

Steps

1. roll your thumb on the ink pad.  
2.   then place your thumb on the balloon.
3.   take your thumb off the balloon.
4.   then blow it up  and look.

Conclusion :

Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

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

Examples are:

1.  Water
2.  Oil
3.  Pool
4. 
   

Materials

1. Funnel x2

2. Container

3. Filter Paper

4. Dirty Water

5. Plastic Cups

6. Sand

7. Pebbles

8. Container

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

Step 1

Cut the bottle..... in to 1/4

Step 2

Put the top half upside down ....... inside the other half of the bottle

STEP 3

Add layers of .... sand then pebbles

STEP 4

Get 1 cup of dirty water ....... and pour it into the bottle

STEP 5

Pour dirty water into ...... upside down half of the bottle

Findings

Write a short sentence about the water every 1 minute. 

Include 'How much water has filtered through', 'How fast it is dripping through', and 'How clear the water is'.

Minutes                          1.                         2.                   3.                    4.                       5.
Drops per minute:  went very fast      went fast            medium          med/slow          slower
Water colour:         brown                    brown               light/dark brown     light/med brown CLEAR
 Conclusion: We cut a bottle in half, turned the to half upside down and put sand , then pebbles. After that we added dirty water, the water was supposed to turn clear but instead it still was dirty brown water. It took five minutes to at least turn lighter then it was at the start. We kept on putting the water back into the cup and then pouring it back into the bottle again and it worked well.
