Lesson Overview

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.

Subject Areas

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

              Enrolling in PrintLab Classroom will give you complete access to the teacher training material and downloadable lesson documents.
