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

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.

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

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.

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.

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.

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.
