Chromatography

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. cup

3. water colour markers Black,green and red.

4. Hot water

5. Ruler

6. pencil

Process:

Step 1: get filter paper

Step 2: fold the paper 2 cm  

Step 3: add the colours by 1 cm

Step 4: put the filter paper in the cup while the edge hangs of outside of the cup.

Step 5: add hot water to where the colours are.

Step 6:watch the colours rise.

Findings: we found out that when they rise up some of the colours mix and made blue.

Reflection: What have I learnt from this experiment I learned that science can make amazing experiments.

Skittles

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

Materials;

1. Petri dish
2. skittles
3. water


Process:

Step 1: get a Petri dish
Step 2: add 5 skittles and put them around the sides of the container.
Step 3:Add water
Step 4: watch it make a pie chart


Findings: we found that when we put water into the petri dish with skittles it make half of the colours on the rainbow and we found out the it can make shapes.
Reflection: we learned that skittles can be used for projects/experiment.

What did the colours do? the colours made pie chart but rainbow.

Did the colours mix together? the colours didn't mix together.

Why or why not? the colours didn't because each food colour has the same amount of sugar dissolved from each skittle.

Extension:

What is another experiment you could do using chromatography and how would you do it. 

Title; Rainbow scratch paper art.

Aim: to make patterns on the paper.

Materials: Long filter paper, black acrylic( it can be any colour but it has to be dark) paint, packing tape, plastic cup, watercolour markers, hot water and maybe ruler and pencil to line up were you put the colours. 

Process: 
Step 1: get all the material you need.
Step 2: get your filter paper add how much colour's you want,fold the edge of the filter paper 2 cm.
Step 3: after the paper is fully covered of colours put the filter paper on the cup leaving the edge on the outside.
Step 4: add hot water to the cup.
Step 5: leave the paper until its dry.
Step 6: add the packing tape all around the paper, cut the paper were you folded.
Step 7: add a thin layer of black paint and make sure that there are no clear spots.
Step 8: make rainbow patterns by scratching them of with tiny tools.
