This is a great summative assessment project that all students love! Whether you are teaching students about sound, waves, music, energy, the human ear, or need an additional hands-on project this project has it all. This is an at home-project that requires students to design, build, and then eventually play their instrument in front of the class in order to be able to explain how sound is created and how energy is transferred.
The design journal students can complete at home in order to hold them accountable for their work and help with time management. The design journal forces students to brainstorm different ideas, draw different designs of what their instrument might look like, record references while they research, and record their "work time" at home, as well as reflect on the process as a whole. The journal is set up in the format of Investigate, Design, Plan, Create, and Evaluate. This project is open-ended and is great for promoting differentiation. I also included voting slips for students to use after the presentations are over as a way to earn extra credit and promote creativity in their work. Students can vote on the instrument they thought sounded the best and the instrument they thought was the most creatively designed.
