Lesson focuses on how engineers design tire treads to increase safety and reliability. Students are presented with the challenge of designing a new tire tread that will be safe when driving in rainy conditions. Student teams will design and construct a sample tread out of clay, then test and evaluate the effectiveness of the design, evaluate their results, and present their findings to the class.
8 – 18
- Learn about engineering design.
- Learn about planning and construction.
- Learn about teamwork and working in groups.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- problem solving
Students learn how tire tread patterns are developed and changed over time to achieve safety and efficiency in a range of driving conditions. Students work in teams to develop a new tread pattern to prevent hydroplaning in heavy rain — first on paper and then by building a clay model. Teams evaluate their own systems and that of other students, and present their findings to the class.
