Toothpick Bridge Design Project Toothpick Bridge Design Project OBJECTIVE: In design teams of 3 or 4 people you will design and draw a plan for an original truss bridge. After your bridge has been designed, you will create a model of that bridge using only toothpicks and glue. Once the models are finished, there will be a Final Challenge to see which bridge design can hold the most weight!! Goals 1. As a team design a Bridge using a simple truss as a starting template. 2. Draw that design as a plan on graph paper. 3. Build the bridge you designed using only toothpicks and glue. 4. Test how much weight the bridge can hold. What is a Simple Truss?? A simple skeletal structure for a bridge. Comprised of many small beams that together can support a large amount of weight and span great distances. All beams in a truss bridge are straight. It spreads the weight the bridge has to hold. How to design a Bridge Each team will receive a handout outlining the different kinds of trusses used in bridge design. Use one of these basic models and design a way to improve upon it. Be Creative! Remember you want your bridge to hold the most weight! Plan Guidelines You will use graph paper to draw a plan of the bridge you design. The bridge cannot be longer than the graph paper (the maximum length of the bridge will be 11 inches). The bridge cannot be more than 3 inches in height. The bridge cannot be more than 3 inches in width. Your Plan must Include: 2 Side View Drawings of your bridge plan. 1 Top View Drawings of your bridge plan.
