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. Enrolling in the lesson will give you complete access to the teacher training material and lesson documents. This includes content to help you prepare and deliver the lessons along with design tutorials so you become familiar with the process prior to teaching it in the classroom.

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 NGSS, CCSS and UK National Curriculum standards. A comprehensive list of standards met is included in the lesson platform.

Learning Criteria

In this project students will:
- develop their basic understanding of sound waves, frequency and amplitude
- understand and discuss the functional design of a whistle
- 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
- develop an understanding of 3D printers and how they operate
- manufacture a functional whistle through 3D printing

Equipment List

Each student will require:
1 x laptop/computer with mouse and internet access
1 x pen/pencil
The teacher will require:
1 x large format screen
1 x 3D printer and PLA filament (http://weareprintlab.com/products)

1 x laptop/computer with mouse, internet access and slicing software (or Polar Cloud) for the 3D printer

1 x frequency/amplitude measurement tool e.g. sound level meter
