Chromatography
The Aim of This Experiment:
To separate colours using chromatography.Materials needed:
- Skittles or M&Ms
- Petrie Dish or a plate
- H2o
Process and Method:
Step 1:
Get a Petrie dish, plate or even a saucer would work just as well (coloured white or transparent will give best results)
Step 2:
Grab your Skittles or M&Ms and arrange them around the edge of the surface with an even space between.
Step 3:
Pour your liquid in, which in this experiment, water, up to approx half the size of the Skittles or M&Ms.
Step 4:
Wait for the process, which could take a few seconds to happen.
Step 5:
Observe what is occurring and how chromatography is working in this experiment/situation.
Step 6:
Hopefully, you have used drinkable water in which case you can the candy.
Conclusion:
The different colours that are in the outside of the Skittles have separeted creating this wonderful effect on the surface that you have done this experiment in. Either a Petrie dish, plate or a saucer. Observing this has taught me more about how chromatography works and how much more it could work on many other compounds out there.
When one thinks about Kennedy's and Johnson's record on civil rights, then it probably isn't such a surprise finding out that these two presidents also spearheaded this national movement for our people with disabilities. study abroad
