Heather is a principal assistant(校长助理). There are 20 classes in her school. Every day, she checks the numbers of students of every class.

One Tuesday, Heather walked into one of the classrooms. For her, nothing was different. But she didn’t know that the students and their teacher would have a fun surprise for her.

After she got into the room, music began. All students started to dance. Then, Heather quickly put her things down and joined them! They danced merrily. They had fun.

In fact, the students and their teacher had the party as an experiment(实验). Every time an educator(教育工作者) of the school walked into their room, they would start the music to see what the person would do.
