On Monday, June 3rd, my class and I did a science activity. We had to do three different science experiments, but first we had to write a hypothesis. The experiments was about mixing colored sugar in different liquids. The liquids we used were oil, water, and vinegar.
The first experiment we did was mixing oil and colored sugar. My hypothesis was, if we put the colored sugar in the oil, then the sugar will sink to the bottom because sugar is heavier than oil and the sugar and oil will not mix. After we wrote our hypotheses, we mixed the the oil and the colored sugar together, and my hypothesis was confirmed. The sugar sunk to the bottom, and the sugar and oil separated.
The second experiment we did was mixing water and colored sugar. My hypothesis was, if we put the colored sugar in the water, then the color on the sugar will spread throughout the water, and the sugar will dissolve. Then, we mixed the water and the colored sugar, and my hypothesis was confirmed. The color in the sugar spread throughout the water, and the sugar dissolved.
The third and final experiment was mixing vinegar and the colored sugar. My hypothesis was, if we put the colored sugar in the vinegar, then the color in the sugar will spread throughout the vinegar, and the sugar will dissolve. My hypothesis for this experiment was similar to the hypothesis for the second experiment. Then, we mixed the vinegar and the colored sugar, and my hypothesis was confirmed. The color in the sugar spread throughout the vinegar, and the sugar dissolved after some time in the vinegar.
All of these experiments have a solvent and a solute. The solute for all of the experiments was the colored sugar. The solvent for all the experiments was the liquids. I learned many things from these experiments and I’m excited to do more in science.
