In the lab, a pupil is conducting an experiment to see how different temperatures affect the dissolving rate of sugar in water. As they pour the water and add the sugar, they watch closely to see what happens, paying attention to any changes in how quickly the sugar dissolves. They also make sure to write down everything they see, keeping track of the time it takes at different temperatures. After looking over their results, the pupil looks for patterns, noticing that the sugar dissolves faster in warm water than in cold.
