Bridge+Project


 * NAME: Hari Demirev CLASS: 4**
 * BRIDGE PROJECT**


 * INVESTIGATE/PLAN

1.** What are the design specifications? (Write the assignment requirements here) **Your bridge should cross over an index card Your bridge should be 5 - 6 inches high Your bridge should 4 - 5 inches wide Your bridge should hold at least 100 pounds You get one handful of popsicle sticks **2.** List the information you gathered and where you gathered it from below: (List at least three) __**Information Where**__ **

Buckling is what happens when the force of compression http://science.howstuffworks.com/bridge1.htm overcomes an object's ability to handle compression

A clamp of some sort is a good idea when constructing http://www.instructables.com/id/Popsicle-Stick-Bridge/

To prevent buckling, it is necessary to make the element stiffer http://andrew.triumf.ca/andrew/popsicle-bridge/

**3.** Describe/draw at least three brainstorming ideas for you bridge:

1. I would make the bridge completely out of triangles that are double-layered. The top would also be made up of interconnected triangles.

2. I would make the bridge completely out of triangles but would also reinforce it with side beams and triangles on the side.

3. I would make the bridge solid or as solid as I could make it with the sticks that I was given. I would try to make it have the least air inside as possible.


 * 4.** Which solution are you going to use? (Choose from #3)

I am going to use my second idea.

5. List at least one success with your bridge: 6. List at least one troubleshooting problem with your bridge: 7. Did your solution solve the problem? 8. What worked well with your design? 9. What did not work well with your design? 10. What would you do differently next time? ** **
