Hurumanu-Rainbow Paper

Aim: To separate colors 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. 2 felt pens

3. a ruler

4. a pencil

5. chromatography paper

6. Water

Process:

Step 1: Use a ruler to rule a line 1 cm from on the bottom of the chromatography paper with a pencil.

Step 2: Use two different colored water-based felt markers and add two reasonable sized dots.

Step 3: Place your paper into the cup before it touches the bottom of the cup.

Step 4: Bend the paper so it doesn't fall in.

Step 5: Add your water.

Step 6: Watch the color spread up the paper.

Hurumanu - Plants

AIM: TO LEARN ABOUT THE NATURE OF PLANTS

Carnivorous Plants

Plants fall into two categories:

1. Evergreen

2. Deciduous

Deciduous

Evergreen

Find three examples of each:

Evergreen: 

1.Magnolia 

2.Pine tree

3.Eucalyptus

Deciduous;

1.Oak 

2.Beech

3.Ashcv                    

LEAVES

Simple                                 Compound   

Activity: Choose a leaf and do a leaf rubbing. Once you have done the rubbing, cut it out and glue it on the tree.

Height- Experiment

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. Yourself

Steps:

1. Get a 1-meter ruler. 
2.  Stand against the wall.
3.  Get your classmate to measure your height
4.  write it down
5.  get the ruler and place your foot next to the ruler and measure from your heel to your toe how big your foot is.

Findings:

Name	Foot  (cm)	Height (cm)
Jasmine	25cm	156cm
Heaven	27.7cm	167cm
Lucy	27cm6	158cm

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.

Flight - Paper

FLIGHT

Aim: To learn about flight and aerodynamics. 

• In your groups of 3, you will make a paper plane and measure its distance and behavior.
• In groups of 3, you will make a water rocket and record its distance and behavior. 

Definition:

the action or process of flying through the air.

4 forces of flight:

1. Gravity   
2. Thurst
3. Drag
4. Lift  

Paper Plane:

Material:

1. Paper
2. paper clip

Steps:

1. create a paper plane.
2. Throw it.
3. Cut litte flaps into the wing's redo step 2

Findings:

Plane Type	Distance	Behavior
Normal	2.2m	curved
Ailerons	2.6m	looped
Paper clip	3.2m	swooped

Conclusion:
The normal plane type went the shortest length because of the science of gravity.
Ailerons Plane's length was 2.6
