This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Sound is an important part of our lives. Many people enjoy listening to music, and watching television would not be the same without sound. On the other hand, noise – loud or unwanted sounds – can make our lives miserable. The booklet provides an overview of the sources of sounds, how sounds interact with materials and how sounds and vibrations are detected. It includes the use of ultrasound waves to detect masses and movement under water, and the range and characteristics of human hearing.
The Sound booklet contains an illustrated overview of the topic with suggestions for teachers on how to introduce the ideas in the classroom, plus student activity sheets and notes for teachers and technicians.
The downloadable resources include:
• Student activities: zip files containing the activity sheets in PDF and editable Word formats.
• PowerPoint presentations: these contain a complete set of the images used in the booklet and activity sheets.
• Further resources include sample sound files and guidance on using sound analysis software.
