Science Experiment on Diffusion - Skittle Rainbow


Age: 9-13 years old

Objective(s):

To demonstrate the concept of diffusion, which is the movement of substance from a region of higer concentration to a region of lower concentration.


Materials:

1. Skittles
2. 1 plate
3. Water

Directions:

1. Line up the skittles on a white plate as shown below.

2. Add some water in the centre so that the water just touch the skittles.

3. Observe what happen for a few minutes. What did you see?

Additional Information:

My niece and nephew are here with us for holidays. We tried this today with my niece, who is on vacation to Denmark, as part of the homework assigned by her school for the school holidays. It was simple, fun and easy to carry it out :-) I am going to do this Science experiment with our Little FECS as well :-)
