In this 4 lesson project, students will embark on a design journey to create a functional 3D printed whistle for their sports department. Lesson 1 begins with a presentation and discussion about sound waves, frequency and amplitude. The class will then go through a 3D modelling tutorial to design and 3D print a whistle. The design tutorial will give students the necessary CAD skills to create their own unique whistle, which is developed as part of an engineering design process in lessons 2-4.
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 ISTE, 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 a basic understanding of sound waves, frequency and amplitude
analyse and understand a variety of oscilloscope sound wave readings
use various research methods to provide them with design ideas to incorporate into their whistle design
use sketching and technical drawing techniques to develop concepts of their whistle
use CAD software to design a functional whistle to accurate dimensions
manufacture a functional whistle through 3D printing
