A bubble by any other name would be just as round, as Rivendell and Pre-K students discovered last week. As part of a math experiment, students in Eve Wood’s class designed three-dimensional pyramids out of strings, straws and candy, and made a prediction about what shape a bubble would create once the form was dipped into soap solution. No matter what shape was in the center of the pyramid, the bubble still came out round, leading to a brief exploration of surface tension, which creates the smallest area for a given volume of air, i.e. a circle.
Later, they had to explain their theory to Pre-K students, and “basically it turned into bubble games,” says Pre-K teacher Michelle Black.
