Chromatography Skittles...

Skittles

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

                               

Materials:

1.  5 Skittles

2.  Petri dish

3.  Water.

Process:

Step 1:  Get one Petri dish or plate to put the skittle on and place the Petri dish on the floor.

Step 2: After you have your Petri dish on the floor get 5 Skittle any colour you like it’s optional.

Step 3: When you have your Skittle spread them out inside of the Petri Dish and spread the Skittle evenly.

Step 4: When you’ve done them get a warm water and pour the water inside of the Petri dish.

Step 5: When you’ve put the water wait a minutes or a second to see the beautiful colours flow in the middle, and wait for the reaction in the end.

Step 6: When you put all of the things inside take a picture of it and share them to your group.

In our Science we were learning about Chromatography ( Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates), we did two experiments in our science today and that is Rainbow Paper and the Skittle. The skittle experiment was really fun and doing the experiment with a group. When we did the experiment there is 5 skittle placing inside of the Petri dish when we pour the warm water the colours from the skittle started spread out and the colour was a lighter shade it was so cool when we were done I was allowed to eat the skittles when we were done the experiment and I was in a group with Sheila and Rieya, and we see that the colours are trying to combined together in a few minutes and one of them are mixed and the other one in not mixed because me and my group always touching it and the colour are combined together and we kinda don’t like the colour when we mixed it. But this experiment is overall fun.
