![]() Sound waves follow the laws of wave behaviour, so they are a useful introduction to wave properties.īy the end of this free resource students will know that sound is produced by objects vibrating and they will understand that sound is a longitudinal wave. Sound is a longitudinal wave of compressions and rarefactions of the material (a rarefaction involves particles in the material being more spread out than usual). Generally, the denser the material, the faster the sound will travel. Sound travels at different speeds in different materials. Many animals make sounds, either for communication or for location. Sounds are vibrations travelling through materials. This is a quick and simple activity that will take approximately 15 minutes. For example, to make ‘silent’ devices to broadcast sound or data between two points. Students could consider how sounds outside the normal spectrum could be used to develop new products. music) about pitch, frequency, amplitude etc.Īs an extension students could produce a display from low to high frequency, showing where the sound ranges used by different animals lie. Use the handout to discuss different sounds and what they might have learned in other lessons (e.g. This activity can be simplified (particularly for less able students) by creating a discussion on why different animals have different hearing ranges and their experience of phenomena such as the Doppler effect. Soundwaves follow the laws of wave behaviour, so they are a useful introduction to wave properties. Make sure students understand sound is a longitudinal wave of compressions and rarefactions of the material. The teacher will first distribute a copy of the ‘Animal Sounds’ handout, which can be downloaded below, to each student. This is so that a student can understand how sound waves travel.Īctivity: Understanding the equation for a sound wave ![]() This engaging STEM activity is aimed at KS3 students and deals with how animals use sounds and how sounds change in natural phenomena. This topic presents students with communications of the past, present and future, helping them to understand the principles that form the basis for these developments. From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. More artists and collaborations will be announced soon, so stay tuned!.įor further inquiries please contact. Other contributing artists include the Red Hot Chili Peppers and The Avett Brothers who have donated stunning signed prints from "Under The Bridge" and "I And Love And You".Īll featured artwork has been created and signed to support the incredible work of Looking Out Foundation and War Child UK with proceeds going directly to The Story Campaign fund. Every piece is hand signed by Brandi and Tim. Current titles include "The Story", "Turpentine", "Josephine" and "The Joke". The collaboration between the Looking Out Foundation and Soundwaves Art creator, Tim Wakefield, features original and limited edition Soundwaves Artwork created from the audio recordings of songs by the incredible Brandi Carlile. The work of the Foundation is made possible by collaborating musicians who give their time to sign artwork to benefit incredible causes. The Foundation and its partners bring Tim Wakefield's truly unique and collectible artwork to music and art lovers alike. ![]() Soundwaves Art Foundation's mission is to find and collaborate with organizations that make a lasting impact on society's greatest challenges.
