Topic: Chromatography

What did students do?

Students folded filter paper as guided. Drew a small circle in the centre with marker and wrote the colour of the marker in the centre. For this activity they used black, brown and blue water based markers. The cone shaped filter paper was then dipped in the transparent glass with a little water so that only the tip of filter paper touched the water. Students observed colours separating from each other and flowing up the filter paper. Different markers were used by students. In the end when colours reached the outer edge of the filter paper they placed it on a paper and dried it.

What did they learn?

In this science experiment, students explored the chromatography (separating mixtures). They used filter papers to separate the various colours of black, brown, red, blue and green markers to see how each color was created alhamdulilah!
