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. ruler  
2. feet 
3. your self

Steps:

1.  get ruler
2.   yourself MEASURE
3.  MEASURE you foot
4.  record it on chart

Findings: 

In my shoe my foot is 23.

Name	Foot  (cm)	Height (cm)
Me	20	143
shania	22	174
kineka	22	174

Divide the length of each person's foot by his/her height. then multiply it by 100. 

Consuelo 

shainia foot is 22 and her HEIGHT is 174.

kineka foot is 22 and her HEIGHT is 174.

MY foot is 20 and my HEIGHT is 143.

they are the same HEIGHT and foot size 

borax crystals,sugar crystals,salt crystals

Borax crystals

Aim: To learn about a saturated solution and how to make crystals.

Hello welcome to my blog today in home room sciences we are going to make borax crystals.

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three you will make three different types of crystals and compare the results.

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) a cup 

2) warm water

3)string

4)populace strike

5)pip cleaners

Process

Step 1:get borax

Step 2:get a Popsicle stick.

Step 3: then sire it up till no borax

Step 4:get some pip wire make i in to star

Step 5:get peg and peg the star

Step 6:pot the peg in and be careful

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) a cup 

2) warm water

3)string

4)populace strike

5)pip cleaners

Process

Step 1:get sugar

Step 2:get a Popsicle stick.

Step 3: then sire it up till no sugar

Step 4:get some string

Step 5: then tie it to a Popsicle stick.

Step 6:pot the string in the water

Salt Crystals

Salt crystals time lapse video

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) a cup 

2) warm water

3)string

4)populace strike

5)pip cleaners

Process

Step 1 get salt

Step 2:get a Popsicle stick.

Step 3: then sire it up till no salt

Step 4:get some string

Step 5: then tie it to a Popsicle stick.

Step 6:pot the string in the water

What crystals worked out best and why?:

Conclusion:

________________________________________________________________________

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	\salt is made with the water from the ocean. And then it will come in a little pool and then the sun boils it an then the water dry up. the salt will be left at the bottom.
Sugar	sugar is made by raw sugar canes and raw sugar is made by sugarcane. and is put in a sugary water
Snowflakes	snow flake is made by the rain and cold air and the rain freeze and then snowflake\ are made.
