An experiment follows the story that gives students the chance to see the principles they have just read demonstrated. The experiment uses a plastic bottle, cold and hot water, and matches to create environments in which clouds could form. Color illustrations accompany the text of the story. At the end of the Cloud Case is a students quiz with questions about facts covered in the Cloud Case. The quiz is graded online and results are sent by email to their teacher.
