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 Tinkercad software. The models are 3D printed, tested, analysed and can be improved in an iterative process. 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, design technology, art and design, physical education, computing and maths. The material 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 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
