3. To see ink split into different colors
Purpose
To see ink split into different colors
The purpose is why we are doing the experiment.

4. Supplies
Filter paper or blotting paper cut into circles with 15cm diameter
Roll of Smarties
Small cup of water
Paper plate
Supplies are the things you will need to be able to do the experiment.

5. Safety Keep the experiment on the plate until it dries or you
might stain the table or your
hands!

6. Procedures Place the plate on a flat surface
Place the paper circle on the plate
Place a Smartie on the center of the paper circle
Dip your finger in the water
Slowly drip drops of water onto the Smartie until it is very wet and there is a circle of water around the Smartie about 5cm across
Wait
Procedures are the steps we take to perform the experiment.

7. Now you can eat your candy!!
Conclusion
You should see rings of color spreading out on the paper from the Smartie
Now you can eat your candy!!
The conclusion is what happens at the end of the experiment.

8. Explanation
Capillary Action-Water flowing through the fibers of the paper
Hydrophilic-Water loving; will dissolve in water
Hydrophobic-Water hating; will not dissolve in water
The ink in the Smartie dissolves in water. The different colors separate because they all weigh a different amount and move at different speeds. The heavier colors stay closer to the candy because they travel slower; the lighter ones move farther away because they travel faster.

9. Altenative Materials Use an M&M instead of the Smartie
Use a felt tip marker to make an ink dot on the paper instead of the Smartie
Alternative means different or other.
