Mobility Aids

The Mobility Aids project will introduce students to the definitions and classes of disability. Students will then be challenged to identify accessibility issues within their school, home or local area and design a solution to the issue. While the project is intended to be a single lesson with printing following the lesson, the project can be extended to a second lesson, if required, by testing the printed designs and suggesting future improvements.
