  1. The Parabolic Bridge Project: Use of Parabolas in Bridge Design by Dr. K. VanFleet

  2. Pre-Project Educational Requirements Students must have knowledge of the following algebraic concepts: • solving quadratic equations and inequalities by factoring and through the use of the quadratic formula • graphing both quadratic equations and quadratic inequalities

  3. I. Technological Component Kinds of Bridgeshttp://bridgepros.com/learning_center/ Beam Arch Suspension Pontoon

  4. I. Technological Component How Bridges Work http://dmoz.org/Kids_and_Teens/School_Time/ Science/Technology/Buildings_and_Bridges/ Article by Michael Morrisseyhttp://www.howstuffworks.com/bridge.htm click on arch bridges, suspension bridges

  5. I. Technological Component Flaws in Bridge Building • article by Michael Morrissey • http://www.howstuffworks.com/bridge.htm • additional bridge • forces • use of iron • solid surfaces

  6. I. Technological Component Engineering as a Career http://www.teachingtools.com/Slinky/engineers.html

  7. I. Technological Component West Point Bridge Designer Students as Engineers use computer software to design and test bridge stability Components: Arch or Suspension Types of metal Thickness of metal Stability Expense

  8. I. Technological Component Review quadratic inequalities, which would be suitable for use in the design of a suspension or arch bridge. • http://matti.usu.edu/nlvm/nav/frames_asid_109_g_4_t_2.html?open=activities

  9. II. Creative Component Each student must choose one of the following: a) Build a Model of a Bridge OR b) Create a 3-D Poster of a Bridge

  10. II. Creative Component A) Build a 3-D Model Guidelines • Type: Arch or Suspension Bridge • Materials: toothpicks, popsicle sticks, wire, glue • Required Length: 1 foot • Required Width: min. 2 ½ in. up to a max. of 6 in.

  11. Guidelines Create a 3-D poster of an arch or suspension bridge Materials: 1 full-size sheet of poster paper Requirements: a) a quadratic inequality representative of the bridge design, b) colorful, c) attached decoration to create 3-D effect such as moss, pebbles, etc. II. Creative ComponentB) Create a 3-D poster
