To enable students who are blind or visually impaired to identify increases in friction
Friction is a force that can be felt. Commonly used activities to demonstrate and experience friction in a regular class room work well for students with visual impairments. Carrying out hands on activities enable the student to feel the ease with which the rock slides along the bare table top, then to compare that feeling to pulling the rock over the gritty sandpaper.
Adapt a traditional spring scale by applying puff paint to the measurement lines.
