Today at school, my class and Ms. Boyer’s class switched rooms for a quick lesson. Ms. Boyer taught science and Ms. Robert taught math.
For the lesson, we did some experimenting with colored sugar and three liquids. We conducted three experiments. For each one, we combined colored sugar with either vinegar, oil, or water. Before the experiments, we made a hypothesis for each one. A hypothesis is the “science version” of an educated guess, kind of like an estimation. My group got to do only two experiments because we ran out of time. We chose to combine colored sugar with vinegar first and then oil. In both the experiments, my group’s hypothesis was confirmed!
For our first experiment, our hypothesis was, “If you combine one teaspoon of colored sugar and twenty-five milliliters of vinegar, then the vinegar will dissolve the sugar and it’ll turn green because of the vinegar’s acidity.” When we conducted the experiment, that’s what happened. The vinegar dissolved the sugar and turned green, which shows that our hypothesis was right. One thing my group noticed, though, was that it took a lot of mixing for the sugar to dissolve completely.
In our second experiment, our hypothesis was, “If we combine one teaspoon of colored sugar and twenty-five milliliters of oil, then the oil will reject the sugar because sugar and water mix and oil rejects water.” And again, when we conducted the experiment, that’s what happened. The oil rejected the sugar and the oil also turned green when the sugar was combined. One thing that my group noticed was that the sugar sank to the bottom because it was denser than the oil.
I thought that conducting these experiments was very fun because whenever my group made a hypothesis, I really wanted to see how the experiment would turn out and whether we would be right. I hope we have another lesson of MESSY SCIENCE!
