Dilutions from a dizzolved crystal

For science last week, we diluted a potassium permanganate crystal in water.  We are learning about dilution and dissolving. To do this we used a measuring cylinder to measure out all of our water. We only got a small amount of the crystal as we were going to use the same water and some extra water to show how it dissolves. From the photo I took, you can tell that the first tube has the most concentrated liquid while the last tube has the most diluted. This is because of the process of dilution. I this photo, you can see that every time, the liquid is more diluted! I like that the process is shown in this photo.

For this experiment, we first mixed in a small amount of Potassium Permanganate with approximatley 100 millilitre's of water. We then added 9 millilitres of this solution into a test tube, and added 1 millilitre of water. After this we proceeded to repeat the process of taking 1 millilitre of the last solution into the next test tube and add 9 millilitres of water. In the diagram below, it shows our results and how the solution looked after being diluted each time

Test tub 1 was the most concentrated solution because it contains the largest amount of solute.  Number 6 was the diluted one because it had contained the smallest amount of solute than other test tubes.
