Aim: To separate colours by using the process of chromatography.
Materials:
1. Skittles
2. Water
3. Petri dish
Process:
Step 1: Get your petri dish
Step 2: Now get your skittles (Put them in the petri dish in a star shape! If you don't the effect won't be as good).
Step 3: Now get some water and pour it in the petri dish. (Also make sure that you don't drown the skittles in water).
Findings: Me and my group started off with 5 skittles (They were in a rainbow order. You can put the skittles in any colour order you want but different colours look more nicer). Then we put them in a star shape, then we re-ordered them in a rainbow order. Finally we put the water in the petri dish and watched the result!
What did the colours do? The colours all come to the middle of the petri dish. At the end they mix together. Our final colour turned out to be Orange.
Did the colours mix together? Yes, the colours do mix a tiny bit when coming into the middle. They all mix at the end.
Reflection
I actually really enjoyed this experiment because we got to learn about Chromatography! I had never really learned about Chromatography before and enjoyed learning about it. We also got to eat the skittles at the end! I also learnt that when the experiment has ended you should NOT drink the water.
Ka pai, awesome job Shreya! Thank you for emailing me your blog link, I really enjoyed looking at your work. You have earned your next point.
