Today in science we finally got to conduct experiments about mixtures and solutions. We had three experiments to do. First we mixed colored sugar with oil. 

In order to do this we had to mix food dye with sugar. We measured 4 teaspoons of sugar with three drop of pink food dye. The food dye mixed in with sugar very easily, but we did need to press it against the sugar at the beginning. Once we made our sugar we wrote our hypothesis. Our hypothesis was if we mix one teaspoon of sugar and oil then it will gradually dissolve and maybe color the oil. Once we conducted the experiment we learned that our hypothesis was wrong. The sugar mostly went to the bottom leaving a thin layer at the top and the oil was in the middle. The oil kept it’s original form and didn’t change when mixed with the sugar. In this solution the sugar was the solute and the oil was the solvent.

Our next experiment to conduct was mixing one teaspoon of sugar with water. Our hypothesis was, if we combine one teaspoon of sugar with water than the sugar will dissolve in the water and the water will change color. When we tested this experiment we learned that our hypothesis was right. The sugar started to dissolve in the water soon after we combined them. We left this solution for an hour and when we came back the sugar was completely dissolved. The water also turned pink, just as we thought. In this solution the sugar was solute and the water was the solvent.

Our final experiment to conduct was adding one teaspoon of sugar with vinegar. Our hypothesis was, if we add one teaspoon of sugar to vinegar then the sugar will partially dissolve and color the vinegar. We then confirmed our hypothesis, the sugar partially dissolved and colored the water. In this solution the sugar was the solute and the vinegar was the solvent.

Overall these science experiments were really fun and I learned a lot!
