This is an interactive Powerpoint presentation suitable for grades 3 and up. It gives an overview of how hearing works, how hearing loss occurs, and how it can be prevented. Emphasis is on noise-induced hearing loss, particularly caused by personal listening devices. The presentation includes a "Guess the Decibel Level" game, and a fun but challenging quiz at the end. See my profile for bookmark templates for students to decorate and add facts from the presentation. This presentation is great to use during Better Speech and Hearing Month!
