Welcome to TVO’s mPower! In this video, we are highlighting one of our creative online Grade 4 STEM Design Challenges, Sound School.
In this game, players apply their knowledge and understanding of the properties of sound to create the ultimate acoustic experience for an audience.
Players apply knowledge of number sense and algebraic reasoning when planning a sound system. A player is successful when they can balance speakers and baffles so the sound’s output reaches the optimal sound range.
Players tap on the purple speaker hot spots to set up speakers. Players consider speaker values and descriptions before making their selection.
Players tap the blue surface hot spots to manage the reflection and absorption of sound. Players consider surface values and descriptions before making their selection. Surface materials can be layered for extra absorption.
Once all the speakers and surface materials are set, players can test their design.
Players use the information on the sound meter to test their sound design. The goal is to hit the “sweet spot” on the sound meter.
Once the player designs a successful sound system, they are invited to give their design a title and to reflect on what they learned, their challenges or what they would do differently next time. From My Gallery, players can then share their sound system with their peers in the Class Gallery.
At the end of the game, players are presented with the STEM Maker Challenge, Sound Solution! Here they are challenged to design, build and test a device that makes use of the properties of sound and solves a problem in the player’s home, school or community. This offers an opportunity for players to apply problem solving, creativity, and innovation to a hands on challenge! They then can share a picture of their engineering in the Community Gallery and receive feedback from peers.
By the end of the game, students should be able to:
- apply knowledge of number sense and algebraic reasoning when planning a sound system;
- apply knowledge of the properties of sound to control sound; and
- design and test a sound system.
