In this 4 lesson project, students will embark on a design journey to create their own functional 3D printed whistle. Lesson 1 begins with a presentation and discussion about sound waves, frequency and amplitude. The class will then go through a 3D modelling tutorial in Tinkercad to design and 3D print a whistle. The design tutorial will give students the necessary CAD skills to create their own unique whistle designs in the next part of the project. In lessons 2-3, students use research and sketching methods before they 3D model and 3D print their own whistle. In the final lesson, students will test their whistles, analyse their designs and consider any improvements.
The lesson can be incorporated into the study of physics, music, maths, computing and design technology and can be adapted for ages 8-16. The curriculum is aligned to NGSS, CCSS and UK National Curriculum standards. A comprehensive list of standards met is included in the lesson platform.
In this project students will:
develop their basic understanding of sound waves, frequency and amplitude
analyse a variety of oscilloscope sound wave readings
use various research methods to provide them with ideas to incorporate into their whistle design
use sketching techniques to design concepts of their whistle
use CAD software to design a functional whistle
manufacture a functional whistle through 3D printing
