Lesson Overview

In this 2 part lesson, students will design and manufacture an assistive bottle opener to help users with arthritis or a weak grip to open screw cap bottles. The lesson teaches about the concepts of simple machines and lever principles, before students design their models in CAD software (Tinkercad & Fusion 360 tutorials included). The models are 3D printed, tested, analysed and can be improved in an iterative engineering design process.

Subject Areas

The lesson can be incorporated into the study of physics, design technology, art and design, physical education, computing and maths (aligned to NGSS, CCSS, ISTE and UK National Curriculum standards). The material can be adapted for ages 8-16. Information on how to adapt the project is included in the lesson plan.

In this project students will:

  • Develop an understanding of levers and simple machines

  • Explore how simple machines exert a bigger force at the expense of smaller movement

  • Communicate design ideas for an assistive bottle opener using 3D, mathematical and computer-based tools

        • Use 3D printing to manufacture a functional assistive tool

        • Test, evaluate and suggest refinements to their manufactured product

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