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.  1-meter ruler 
2. yourself

Steps:

1.  get the metre ruler and find out how high you are and your foot length
2.  write down the information on a chart
3.  foot size divided by your height = ? x 100 =?

Findings:

19.4444444444%

Name	Foot  (cm)	Height (cm)
kade	28cm	144cm
Joshua	28cm	152cm

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.

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.  dirt filter
2.  water filter
3.  oil filter 

Materials

1. filter paper

2.container

3.funnel 

4.Pebbles

5.sand

6.

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 

STEP 3

Add layers of filter paper sand and Pebbles

STEP 4

Get 1 cup of dirty water 

STEP 5

Pour the dirty water into the top

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.

Conclusion:

in conclusion, if I had multiple different layers I think it would work a heat load better.the water was still brown and Mickey when we first got it out of the machine.I might have a go at doing some other stuff with things to try to make it better.

FLIGHT

Aim: To learn about flight and aerodynamics. 

• In your groups of 2, you will make a paper plane and measure its distance and behavior.
• In groups of 2, you will make a water rocket and record its distance and behavior. 

Definition:


4 forces of flight:

1. lift         

2.gravity

3.drag 

4.thrust

Paper Plane:

Material:

1. paper
2. paper clip

3. ruler

Steps:
 

Findings:

Plane Type	Distance	Behavior
Normal	3.0	Spinning
Ailerons	2.0	Upwards,swooped-up and down
Paper clip	4.0	Straight line.

Conclusion:

In conclusion, I learned that the paper plane with the paperclip flies further because of the fourth the paperclip as pulling it 4.0 Straight line. I learned that ailerons slow the plane down to land 2.0 Upwards,swooped-up and down. the normal plane flew 3.0 Spinning. 

the plane with the ailerons flew the farthest.

Water Rocket

Findings:

( Record the distance and the flight behavior of your rocket.)

Fuel Amount	Test 1	Test 2	Test 3

Conclusion:

Fabrics

In Fabrics, I had a chance to make whatever I wanted so I had a look around I saw a basic cactus shape that gave me an Idea to make a 3D cactus. My first job was to draw the plan for it. My second job was to make a mock-up for all the pieces I needed. My third job was to cut the material up and sew all the pieces together Here are some tools and techniques. I used hand stitching, needle sewing, sewing machine and running stitch. My final job was to put on the Finishing Touches.

Aim: To see which chemical 
the mix creates the most gas.

Hypothesis: baking soda and vinegar 


Materials:

1.  3 Balloons
2. 3 bottles
3.   3 tsp baking soda,
4.  ½ cup vinegar
5.  3 tsp salt,
6.  ½ cup soda
7.  2 tsp yeast, 
8. 1 tsp sugar 
9. funnel
10. warm water

Steps:

1.  put all the liquid ingredients into the bottom of the funnel
2.  put all the solid ingredients into the balloon
3. quickly put the balloon on top of a bottle
4.  wait 20 minutes and measurer in cm.
5.  put information on the graph

My images:

Findings: baking soda and vinegar 

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	20cm	6/2cm	13cm
Bubbles	a few	a few	heaps

Conclusion: I found the baking soda and vinegar raised the most. the yeast and sugar rises of the slowest. the last thing I learned is that all these mixtures release carbon dioxide

STOP.WRITE.HEAR

This is my group storyboard of STOP.WRITE.HEAR

our next step for today to create all the models and characters for the set.

Aim: To separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Scenario

A crime has been committed. The police have a signed cheque and a letter from the same crime scene but it seems like the handwriting is different. They have 3 suspects but not enough evidence. They need to know if the letter and the cheque were written by the same person.

How do they tell if the pens used for both of these pieces of evidence are the same?

Rainbow paper

Materials;

1. cup

2. chromatography paper

3. water-based pens

4. water

Process:

Step 1: get chromatography paper one cm up the paper and pot water-based pen bots.

Step 2:  Get a cup to fill 1/2 cm of water on the bottom of it.

Step 3: wait for about 10 minutes.

Step 4: done should have a rainbow going up your paper

Conclusion: What have I learned from this experiment? black is the best color for doing this. purple is the second best color. there's such thing as chromatography paper.
