Science experiments

Today in class we conducted 3 experiments with colored sugar, oil, water, and vinegar.

The 1st experiment we did was water and colored sugar, the solute was the sugar and the solvent was the water. Our hypothesis was: If we mix the water and colored sugar together the sugar will color the water, then the colored sugar would dissolve faster than in the oil. The first part of my hypothesis was confirmed because the colored sugar colored the water and the sugar lost its color, but the sugar did take a while to dissolve. The sugar all went down the bottom of the cup. The 2nd part of the hypothesis was unknown till the 2nd experiment.

In the 2nd experiment we mixed colored sugar water and oil together, the solute was the sugar and the solvent was the oil. Our hypothesis was: If we mix colored sugar and oil together, then the sugar will not color the oil, because it is thicker than water. The hypothesis was confirmed because the colored sugar did not color the oil. The sugar also did not dissolved in the water maybe because there is not enough water in the oil. In my 1st experiment, the 2nd part to my hypothesis was partially right, because the sugar dissolved in the water but not in the oil.

In my 3rd experiment we mixed vinegar and colored sugar, the solute was the sugar and the solvent was the vinegar. Our hypothesis was: If we mix colored sugar and vinegar together, then the sugar will not dissolve. Our hypothesis was denied because the sugar quickly dissolved into the vinegar a lot faster than the water. When the colored sugar dissolved it colored the water, but the vinegar made the color turn darker. These 3 experiment were really fun to do and I learned that liquids that are almost alike can have different effects on the same thing. I also learned that vinegar can change the color of things.
