Science

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. paper
2.  pens
3. water
4. cup 
5. 
6. 

Process:

Step 1: We had to get a cup.
Step 2: We needed to get some colours. 
Step 3:We needed to get some water from the teacher.
Step 4: We had to put the colours on the paper and put it in the cup and put some water in the cup and it will change colours.
Step 5:
Step 6:


Conclusion: What have I learnt from this experiment?

 Chromatography

What is a Chromatography.

Chromatography is a separating method scienist of a police use is  separates the material from the pattern. 

You can do a Chromatography at home if you like because it is a great thing to do and you will need materials for this. They are a cup so colours and and paper. And then you will need to put some water in the cup so the colours will turn colours when you put the water in. But if you put 3 colours on the papper it want work other ways . So this is what it is chromatography.

Today we are doing a blog post because it is our art that we are doing today. My group has two bully's and three nice people in my group and the two bully's are sapphire and lily the three good people the three people are kahciar makenzie and me. And me and they are playing on the on the playground. Because it was really cool to play on the playground and the bully's came along and the came and pushed me kahciar and Mackenzie of the playground.

The feedback that we got was.


We liked how you labled the people so we can see whos, who .
You  could probably do your handwriting a little bit better.
we like the way that you drew the props so that we can see what they are.
