Entry Events
Events that will be used to introduce the project to studentsSuperhero Silent Shields Workshop
Students are introduced to the world of superheroes and their gadgets through a surprise comic book. Their task is to become 'Sound Superheroes' and create noise-canceling devices as their superhero shield, relating directly to their interest in popular superhero films. This concept encourages imaginative problem-solving and inquiry into how sound waves can be manipulated.The Sound Wave Escape Room Challenge
A classroom transforms into an escape room where students must solve puzzles related to sound waves to 'escape'. Each puzzle involves understanding how noise-canceling technology works, fostering their inquiry skills. This exciting and hands-on entry invites students to rethink how sounds can be controlled or used as an advantage to achieve a goal.Portfolio Activities
