In this activity, students in grades 3 to 6 learn about force and friction by examining how basic rim bicycle brakes work and discussing the advantages of various designs. They then use low cost materials to devise a simple braking system, suggest improvements to current bicycle brake designs, and present their recommended changes to the class.
