CARDBOARD CHAIR DESIGN and CONSTRUCTION Moussa Ndiaye Shroder

CARDBOARD CHAIR DESIGN and CONSTRUCTION Moussa Ndiaye Shroder HS, Calculus Big Idea/Challenge Big Idea Reuse waste, CEEMS is funded by the National Science Foundation, grant # 1102990. Unit Activity Implementation Student Work and Results • Activity 1: Chair Design Essential Data Table 10 Reduce waste, and Save Money 9 8 7 • Activity 2: Sketches of the chair Challenge Build a cardboard chair that can seat 200 lbs. person without any fasteners and minimize the cardboard waste 6 pre-test 5 post-test 4 • Activity 3: Scale-Model of Chair 3 2 1 0 • Activity 4: Building Plan 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 The average score on the Pre Assessment was a 32% The average score on the Post-Assessment was 47% Unit Structure Guiding Questions • Activity 5: Building a Full-Scale Chair (The Challenge) • Why is recycling important? • How can I develop a protocol to select the best chair design for production? Standards • Activity 6: Presentation The College Board states that: Student should be able to determine antiderivatives, indefinite and definite integrals, use definite integrals to find areas of planar regions Objectives Student will ACS: Applications/ Career/ Societal impact • construct a scale model of their chair using index cards (A) Ability to use of Riemann sum to estimate the area of • construct their chair using cardboard • Evaluate the are of the cardboard using Riemann Approximation the cardboard being used (B) Automotive Engineering, Drafting and design engineering and Environmental engineering (C) Reduce waste, Save money, Reduce the use of energy Reflection and Conclusion This unit was a success • Students applied Riemann sum in the context finding surface area • Students met stated learning objectives • Students owned their projects and presented their designs with pride • The next time For the group of students that did not finish I will assign role each step along the way
