Optimizing School Chair Comfort
Design a comfortable cushion to minimize pressure when sitting in school chairs. Students rate chair comfort and brainstorm improvements. The challenge is to create a portable cushion using provided materials. Following the engineering design process, groups sketch, test, and build their designs for evaluation.

TAKE A SEAT! MINIMIZING PRESSURE AND OPTIMIZING COMFORT IN SCHOOL CHAIRS
POLL THE CLASSROOM 1. Rate the comfort of your school desk chair on a scale of 1 (most uncomfortable chair I ve ever sat in) to 5 (most comfortable chair I ve ever sat in). 2. True or False: I am comfortable in my seat right now. 3. Improvement: Brainstorm with a partner 1 or more ways that the school desk chair could be improved.
THE PROBLEM As identified by our classmates, we can agree that our school desk seats are not as comfortable as they could be. According to this article in The Guardian : The average child spends 15,000 hours sitting on chairs during their school life. One in five of children suffer back pain and three students from every classroom will see a doctor before their 16th birthday with complaints of back pain. These chairs are mass-produced without comfort in mind.
THE CHALLENGE Your Task: Design a cushion that minimizes the pressure felt when sitting down. Criteria: Your cushion must be able to fit on a chair and on the capacitance sensor. Your cushion must be portable to take from class to class. Constraints: Your cushion must only use supplies provided by, or approved by, your teacher. Your cushion must be built within the allotted time.
ENGINEERING DESIGN PROCESS Sketch: Test: Build: Your group will first create a sketch and list of materials needed for your cushion idea. Each group will then test the success of their design using the capacitance sensor they built! Your group will create your cushion using materials in- class. Don t forget about the criteria and constraints while you are building! The sketch must be approved by teacher. Whose design will be the most successful?
