What is Chromatography?

The word ‘chromatography’ is made of two words: chromo and graphy. The first word means colour and the second word means to write. The term has been derived from a Greek word. The technique is used to separate different components in a mixture by dissolving one substance, called the mobile phase, into another substance, called the stationary phase. 

In chromatography science experiment, the paper becomes the stationary phase, and water is the mobile phase. Another essential aspect of chromatography is that it depends on the mobile phase’s speed, flowing through the stationary phase.

How to Make Flowers using chromatography science experiment at Home?

Making flowers using chromatography science experiment is a great way to help children learn fast in a fun-filled manner. It becomes vital because kids love colours and find it interesting to combine colours to produce exciting results. Using these experiments, children can separate colours or merge colours, and learn how different hues intermix to form varied colours in the universe. This chromatography science experiment can be done by kids of all ages – across preschool, grade 1, 2, 3, and 4.

Making chromatography flowers at home can be treated as both a science or art project as per your choice. Parents and teachers can look for online resources and get ideas about the different ways chromatography can be used for conducting relevant chromatography science experiment at home and in the classroom.

Materials Required for Chromatography science experiment

  • Water
  • Tablecloth for protecting the table surface
  • Small syringes or cups filled with water
  • Coffee filters. Take white coloured filters. You can also use chromatography filters that are specially made for such science experiments for kids.
  • Secondary and tertiary coloured markers. Ensure that these are watercolour markers or water-based sketch pens.
  • Green-coloured pipe cleaners. You can alternately use twigs or small-sized sticks.
  • Clear tape

Steps to Follow for performing Chromatography science experiment 

Step 1

First, you need to crush and level out the coffee filters.

Step 2

Draw a circle on the filters using one colour. Make the circle bold and thick. You need to use secondary colours like black, green, red, orange, pink, yellow, purple, and brown. You can make half-circles with one colour, and the other half-circle with another colour.

Step 3

Next, you need to fold the filter in half, and then another half to form a cone.

Step 4

Use small, short glasses and fill them with drops of water. Now, open the cone top and let the tip of the cone into the water. Ensure that only the end dips into the water, and not the circled part. Alternatively you can add water drops to each of the coffee filter papers using a syringe. As the liquid spreads, kids will be delighted to observe the colour molecules’ separation as the water molecules spread across the filter.

Step 5

If you want the water to spread further, add one or two drops of water to the filter. The further the water spreads, the colour will also spread further, making it all look attractive. When the water reaches the edge of the filter, you can take the filters out.

Step 6

Now wait for the water to dry.

Step 7

Once the coffee filters are completely dry, you can use the filters for making chromatography flowers at home. The kids will be amazed at the vast expanse of colours that have separated and dried on the coffee filters. Cut the filters across the edges.

Step 8

Take some of the filter papers together and bundle them up to give them the shape of a flower. Ensure that you twist the bottom in a funnel shape so that the ends can be easily attached to the green-coloured pipe cleaners, and use the clear tape to fix the filter papers.

chromatography science experiment for kids is fun

Your bouquet of chromatography flowers at home is now ready! Kids would be proud of their work. It is a beautiful work of craft, prepared using the science of chromatography. Once kids have understood the concept, they can use it to make not only chromatography flowers at home, but also colourful butterflies, and various other vibrant and beautiful items.

Conclusion

chromatography experiment for kids

We are aware that different colour molecules mix to make one colour that our eyes can perceive. A single colour can be separated into the different pigments present in the colour with chromatography science experiment. We use coloured markers, and the ink of the features spread across the filters by using water. The eyes can visually see these separate pigments, as we have already discussed that paper chromatography uses water and paper. 

When water moves through the coloured paper, it distinguishes and separates the colours. Water molecules pass through different colours at different speeds. As the water moves and the first colour separates, we can see the colour distinctly. Then, the second colour separates, and likewise, it continues.
