This curriculum was designed to help teachers teach their fourth-grade students about hearing and the effects of loud noises on hearing. The program describes the human ear and how it works, explains the health effects of noise, and offers ways for students to protect their hearing from unsafe noise levels. Students are taught how hearing is measured, the types and causes of hearing loss, and how to share this knowledge with other students through posters that they have designed. Four classroom sessions are described; overheads for each session are included. Concepts are explained using pictures, diagrams, and games. Children's pre- and post-program questionnaires are included as well as a teacher evaluation form and a letter to parents that explains the program. A hearing fact sheet is appended that offers analysis of the many sounds that surround people in their daily lives. A listing of materials needed for the program is included, such as folders, overhead projector, video machine, radio, anatomical ear model, and earplugs. Curriculum references and sources are listed.
