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. tow people 
2. one meter ruler

Findings:

Name	Foot  (cm)	Height (cm)
Makenzie	22 cm	145 cm
Sapphire	26 cm	179   cm
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.

Finger prints

Fingerprint characteristics

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.
5.   

Insert two pictures here of your fingerprints

Ink prints

Thumb print	Index finger print

Record the types of fingerprints from those in your group.

Name	Fingerprint 1 (Thumb)	Fingerprint 2 (index finger)
Maknzie	arch	arch
Skye	arch	arch

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.

Maths (DLO)!!!😃

Hey readers today's blog post is about rounding numbers here is a google drawing on how to round number.

skittles

Skittles

Aim: To separate colours from skittles by using the chromatography.

Materials;

1. skittles 
2. a plat or petri dish.
3. water
Process:

Step 1:get some skittles five works good.
Step 2:put the skittles round the dish the you picked.
Step 3:then put water in the dish and wait and look to see what happens.
Step 4:
Step 5:
Step 6:

Conclusion: What have I learnt from this experiment?
I learnt that when you put skittles in water they lose there colour and the water tastes like skittles and that the colour does not mix's with the other colours.

 

art the playground

Hey readers today's blog post is about art that we did at school it is a story about two bully's at a park.
Here is a pic of the story.









The next step are two finish the story.
Positive we liked that you labelled each box.
Helpful make the drawings and hand writing a bit better.
Thoughtful we like how you did the props so we know what they are.

Plum jam!!!

Hey readers today blog post is about the schools plum jam.

 I made this on a google drawing with pics of plums and jam the reason that we are doing this is because the year 7&8 at Hornby High made plum jam for our comity impact project they went out and picked plums and made jam and are sealing it for $3 I will update this post when i know when this takes place and where.
