Six classes, six teachers—just navigating middle school is a voyage of discovery for early adolescents. Students are offered a confusing array of choices, many in science. Sometimes it seems teachers spend too much science class time teaching organization, caution, and control. But these skills—critical to making science experiences exciting and safe—are also important science processes. These years offer wonderful opportunities to capture students’ energy and channel it toward the excitement of scientific exploration. But everything teachers do in middle school science classrooms must recognize the developmental level of our young scientists and their penchant for risk-taking that we must temper sufficiently to promote safety.
