Chromatography

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

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials;

1. Filter Paper

2. Container

3. Felts

4. Liquid

5. Ruler

6. Pencil

Process:

Step 1: You have get one filter paper the thinner version of you normal filter paper so water can soak faster through it.

Step 2: Rule two lines on the paper with a pencil. You have to put it vertically and at the top draw a a line 2 cm apart from the top of the paper ans at the bottom draw a 1 cm line apart from the bottom of the paper.

Step 3: Get some felts and they have to be water based felts make sure you get three felts of any colour of your choice but ideal is black, red and green so you can get a surprising reaction.

Step 4: On the paper put 3 different colour dots with you water based felts on the bottom 1 cm line, it can be in any order of colour you want also for best result make the dots big but not to big.

Step 5: Fold the 2 cm paper line making a flap you can fold it any side you want since the colour can go through both sides.

Step 6: Grab a container or in other words a cup and hang your  paper making sure the longer side is facing the inside of the cup. - Make sure the paper is just above the bottom of the cup.

Step 7: Pour such a little amount of liquid or water into the container/cup making sure the top of the water is touching only the end of the Filter paper.

With My experiment and my buddy Sheila was a success I was so surprised of what happened, we learning or experimenting what colours were inside a colour that really got us confused at the start but after the result of the our experiment started to get what Mr palmer and Whaea Jo was talking about. We used the colours black, red and green they are just ordinary colour but when we added water and the filter paper started to soak up the liquid and get to the colour. The colours started to change the black turned into a rainbow the the red turned into pink and the green turned into a yellow and blue colour it was so cool. While was soaking higher more colours started to appear and the colours also spread up with the water although the bottom of black and green disappeared and was only at the top. I would really recommend trying this at home and try this experiment again.

Skittles

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

Materials;

1. Skittles

2. Petri Dish

3. Water/Liquid

Process:

Step 1:  Get a Petri Dish or a flat plate that is curved up on the sides.

Step 2: Place how many skittle in any order and any colours you want it in.

Step 3: After places all you skittles in you have to add warm water to just nearly over under the top of the skittles.

Step 4: Wait… it will take a few seconds or minutes for all the beautiful colours flow to the middle.

Step 5: Observe and record, it is optional but you can record while you observe it.

Step 6: Photo and Share, This is also optional but it will be nice if you can take photo of it and share it on social media or a blog.

Findings: Today for science we were learning about Chromatography, we did two experiments on it one about rainbow paper and one about Skittles. The skittles one was really fun actually really delicious after the experiment we could eat the skittles but at first when we started the experiment. It was blant we couldn't see any improvement but when time passed by we saw so much colour it was pretty the colours started to join and after a few minutes it mixed into a colour nobody actually likes. We actually had to container. So we compared the both of them and one was mixed and the other one was not one was mixed because we were kind of moving it a lot probably if we didn’t that wouldn’t have happened. But overall it was really fun.
