SafetyNET TIJ Scale Electric Car

Description

TIJ students design and create a scale model electric car that travels the length of a hallway in a straight line. Project is appropriate for grades 9 and 10, to be completed over 15-20 70 minute periods. Project scope – This is a suburban school with a class size of approximately 20. I believe it would work in a larger class or in a rural setting also. There are some specific safety issues with this project so experience with making circuit boards safely in a classroom (generally now done by the teacher because of risk with chemicals and UV light exposure) is essential. Students can complete 'design' points, however, likely legally in most boards, it's preferred that the teacher handles the chemicals for circuit board creation. You will need to investigate what other teachers in your board are doing for electronics projects like these. I've provided options for both a wood body and a vacu-formed body creation depending on the resources you have access to. This project is an excellent starting point for Grade nine students as it does not require any of the large stationary machines. Once the design process is complete the students can begin construction using the band saw or scroll saw. I have found both tools to be a lower risk factor as compared to the table saw for example, and as a result they are busy creating their project. Those who are self directed and comfortable with the building process can progress independently allowing the teacher to spend time with those who need more assistance. On the design side it allows for either a high level of creativity with the creation of their own body blank or plug or use one of the previously created moulds. This is a project that go either way and still be successful for a wide range of student’s abilities. In the broad spectrum of looking at this project the goal is to: Introduce and practice the design process, Problem solving – with gearing, performance issues,etc., Practice measurement and layout skills, Intro to tool use and building process, Follow safe practices and procedures when using materials, tools, and equipment.
